Circular economy (CE), also referred to as circularity, is a model of resource production and consumption that involves sharing, leasing, Reuse, repairing, refurbishing, and recycling materials and products, to extend product life cycle for as long as possible. The concept aims to tackle global challenges such as climate change, biodiversity loss, waste, and pollution by emphasizing the design-based implementation of the three base principles of the model. The main three principles required for the transformation to a circular economy are:
Circular economy is defined in contradistinction to the traditional linear economy. The idea and concepts of a circular economy have been studied extensively in academia, business, and government over the past ten years. It has been gaining popularity because it can help to minimize carbon emissions and the consumption of raw materials, open up new market prospects, and, principally, increase the sustainability of consumption. At a government level, a circular economy is viewed as a method of combating global warming, as well as a facilitator of long-term growth. Circular economy may geographically connect actors and resources to stop material loops at the regional level. In its core principle, the European Parliament defines the circular economy as "a model of production and consumption that involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended." Global implementation of circular economy can reduce global emissions by 22.8 billion tons, equivalent to 39% of global emissions produced in 2019. By implementing circular economy strategies in five sectors alone: cement, Aluminium, steel, , and food, 9.3 billion metric tons of equivalent (equal to all current emissions from transportation) can be reduced.
In a circular economy, business models play a crucial role in enabling the shift from linear to circular processes. Various business models have been identified that support circularity, including product-as-a-service, sharing platforms, and product life extension models, among others. These models aim to optimize resource utilization, reduce waste, and create value for businesses and customers alike, while contributing to the overall goals of the circular economy.
Businesses can also make the transition to the circular economy, where holistic adaptations in firms' business models are needed. The implementation of circular economy principles often requires new visions and strategies and a fundamental redesign of product concepts, service offerings, and channels towards long-life solutions, resulting in the so-called 'circular business models'.
The circular economy is a framework of three principles, driven by design: eliminating waste and pollution, keeping products and materials in use, and regenerating natural systems.
Other definitions and precise thresholds that separate linear from circular activity have also been developed in the economic literature.
In a linear economy, are turned into products that are ultimately destined to become waste because of the way they have been designed and manufactured. This process is often summarized as "take, make, waste". By contrast, a circular economy aims to transition from a 'take-make-waste' approach to a more restorative and regenerative system. It employs reuse, Sharing economy, repair, refurbishment, remanufacturing and recycling to create a closed-loop system, reducing the use of resource inputs and the creation of waste, pollution, and carbon emissions. The circular economy aims to keep products, materials, equipment, and infrastructure in use for longer, thus improving the productivity of these resources. Waste materials and energy should become input for other processes through waste valorization: either as a component for another industrial process or as regenerative resources for nature (e.g., compost). The Ellen MacArthur Foundation (EMF) defines the circular economy as an industrial economy that is restorative or regenerative by value and design.
Circular economy strategies can be applied at various scales, from individual products and services to entire industries and cities. For example, industrial symbiosis is a strategy where waste from one industry becomes an input for another, creating a network of resource exchange and reducing waste, pollution, and resource consumption. Similarly, circular cities aim to integrate circular principles into urban planning and development, foster local resource loops, and promote sustainable lifestyles among their citizens. Less than 10% of economic activity worldwide in 2022 and 2023 is circular. Every year, the global population uses approximately 100 billion tonnes of materials, with more than 90% of them being wasted. The circular economy seeks to address this by eliminating waste entirely.
The concept can be linked to various schools of thought, including industrial ecology, biomimicry, and cradle-to-cradle design principles. Industrial ecology is the study of material and energy flows through industrial systems, which forms the basis of the circular economy. Biomimicry involves emulating nature's time-tested patterns and strategies in designing human systems. Cradle-to-cradle design is a holistic approach to designing products and systems that considers their entire life cycle, from raw material extraction to end-of-life disposal, and seeks to minimize waste and maximize resource efficiency. These interrelated concepts contribute to the development and implementation of the circular economy.
In the end half of the 19th century, an early major effort to promote ideas now labeled the circular economy was headed by the Society for the Encouragement of Arts, Manufactures and Commerce now. As documented by economic geographer Pierre Desrochers, RSA contributors argued that the profit motive, long-distance trade, and actors now largely absent from present-day discussions (e.g., waste dealers and brokers) promoted the creation of ever more value out of manufacturing and other residuals.
In the 1968 book General System Theory, biologist Ludwig von Bertalanffy, considers growth and energy for open and closed state systems. This theory was then applied to other areas, such as, in the case of the circular economy, economics. Economist Kenneth E. Boulding, in his 1966 paper "The Economics of the Coming Spaceship Earth", argued that a circular economic system is a prerequisite for the maintenance of the sustainability of human life on Earth. Boulding describes the so-called "cowboy economy" as an open system in which the natural environment is typically perceived as limitless: no limit exists on the capacity of the outside to supply or receive energy and material flows.
In the 1981 book Jobs for Tomorrow: The Potential for Substituting Manpower for Energy, Walter R. Stahel and Geneviève Reday-Mulvey lay the foundation for the principles of the circular economy by describing how increasing labour may reduce energy intensive activities.
Simple economic models have ignored economy-environment interrelationships. Allan Kneese in "The Economics of Natural Resources" indicates how resources are not endlessly renewable.
In the 1990 book Economics of Natural Resources and the Environment, Pearce and Turner explain the shift from the traditional linear or open-ended economic system to the circular economic system.
In the early 2000s, China integrated the notion into its industrial and environmental policies to make them resource-oriented, production-oriented, waste-oriented, use-oriented, and life cycle-oriented. The Ellen MacArthur Foundation was instrumental in the diffusion of the concept in Europe and the Americas.
In 2010, the concept of circular economy started to become popular internationally after the publication of several reports. The European Union introduced its vision of the circular economy in 2014, with a New Circular Economy Action Plan launched in 2020 that "shows the way to a climate-neutral, competitive economy of empowered consumers".
The original diffusion of the notion benefited from three major events: the explosion of raw material prices between 2000 and 2010, the Chinese control of rare earth materials, and the 2008 economic crisis.L'
Of particular concern is the irrevocable loss of raw materials due to their increase in entropy in the linear business model. Starting with the production of waste in manufacturing, the entropy increases further by mixing and diluting materials in their manufacturing assembly, followed by corrosion and wear and tear during the usage period. At the end of the life cycle, there is an exponential increase in disorder arising from the mixing of materials in landfills. As a result of this directionality of the entropy law, the world's resources are effectively "lost forever".
Circular development is directly linked to the circular economy and aims to build a sustainable society based on recyclable and renewable resources, to protect society from waste, and to be able to form a model that no longer considering resources as infinite. This new model of economic development focuses on the production of goods and services, taking into account environmental and social costs. Circular development, therefore, supports the circular economy to create new societies in line with new waste management and sustainability objectives that meet the needs of citizens. It is about enabling economies and societies, in general, to become more sustainable.
However, critiques of the circular economy suggest that proponents of the circular economy may overstate the potential benefits of the circular economy. These critiques put forward the idea that the circular economy has too many definitions to be delimited, making it an umbrella concept that, although exciting and appealing, is hard to understand and assess. Critiques mean that the literature ignores much-established knowledge. In particular, it neglects the thermodynamic principle that one can neither create nor destroy matter. Therefore, a future where waste no longer exists, where material loops are closed, and products are recycled indefinitely is, in any practical sense, impossible. They point out that a lack of inclusion of indigenous discourses from the Global South means that the conversation is less eco-centric than it depicts itself. There is a lack of clarity as to whether the circular economy is more sustainable than the linear economy and what its social benefits might be, in particular, due to diffuse contours. Other issues include the increasing risks of cascading failures which are a feature of highly interdependent systems, and have potential harm to the general public. When implemented in bad faith, touting "circular economy" activities may be used for reputation and as impression management for public relations purposes by large corporations and other vested interests; constituting a new form of greenwashing. It may thus not be the cure-all many had hoped for.
The circular economy includes products, infrastructure, equipment, services and buildings
The organization Circle Economy reported that global implementation of circular economy can reduce global emissions by 22.8 billion tons, 39% of global emissions in the year 2019. By 2050, 9.3 billion metric tons of equivalent, or almost half of the global greenhouse gas emissions from the production of goods, might be reduced by implementing circular economy strategies in only five significant industries: cement, aluminum, steel, plastics, and food. That would equal to eliminating all current emissions caused by transportation.
The circular economy is grounded in the study of feedback loop-rich (non-linear) systems, particularly living systems. The contemporary understanding of the circular economy and its practical applications to economic systems has evolved, incorporating different features and contributions from a variety of concepts sharing the idea of closed loops. Some of the relevant theoretical influences are cradle to cradle, laws of ecology (e.g., ), looped and performance economy (Walter R. Stahel), regenerative design, industrial ecology, biomimicry and blue economy (see section "Related concepts").
The circular economy was further modelled by British environmental economists David W. Pearce and R. Kerry Turner in 1989. In Economics of Natural Resources and the Environment,
In the early 1990s, Tim Jackson began to create the scientific basis for this new approach to industrial production in his edited collection Clean Production Strategies, including chapters from preeminent writers in the field such as Walter R Stahel, Bill Rees and Robert Costanza. At the time still called 'preventive environmental management', his follow-on book synthesized these findings into a manifesto for change, moving industrial production away from an extractive linear system towards a more circular economy.
Considered one of the first pragmatic and credible sustainability , the main goals of Stahel's institute are to extend the working life of products, to make goods last longer, to reuse existing goods, and ultimately to prevent waste. This model emphasizes the importance of Service economy rather than products, an idea referred to as the "functional service economy" and sometimes put under the wider notion of "performance economy." This model also advocates "more localization of economic activity".Clift & Allwood, "Rethinking the economy", The Chemical Engineer, March 2011
Promoting a circular economy was identified as a national policy in China's 11th five-year plan starting in 2006. The Ellen MacArthur Foundation has more recently outlined the economic opportunity of a circular economy, bringing together complementary schools of thought in an attempt to create a coherent framework, thus giving the concept a wide exposure and appeal.
Most frequently described as a framework for thinking, its supporters claim it is a coherent model that has value as part of a response to the end of the era of oil price and materials and, moreover, contributes to the transition to a low-carbon economy. In line with this, a circular economy can contribute to meeting the COP 21 Paris Agreement. The emissions reduction commitments made by 195 countries at the COP 21 Paris Agreement are not sufficient to limit global warming to 1.5 °C. To reach the 1.5 °C ambition, it is estimated that additional emissions reductions of 15 billion tonnes of per year need to be achieved by 2030. Circle Economy and Ecofys estimated that circular economy strategies may deliver emissions reductions that could bridge the gap by half.
One prominent thinker is Walter R. Stahel, an architect and economist who is "generally regarded as the father of circular economy" and industrial sustainability. Having also been credited with coining the expression "Cradle to Cradle" (in contrast with "Cradle to Grave", illustrating our "Resource to Waste" way of functioning), in the late 1970s, Stahel worked on developing a "closed loop" approach to production processes, co-founding the Product-Life Institute in Geneva. In the UK, Steve D. Parker researched waste as a resource in the UK agricultural sector in 1982, developing novel closed-loop production systems. These systems mimicked and worked with the biological ecosystems they exploited.
Another report by WRAP and the Green Alliance (called "Employment and the circular economy: job creation in a more resource efficient Britain"), done in 2015 has examined different public policy scenarios to 2030. It estimates that, with no policy change, 200,000 new jobs will be created, reducing unemployment by 54,000. A more aggressive policy scenario could create 500,000 new jobs and permanently reduce unemployment by 102,000. Estimating Employment Effects of the Circular Economy The International Labour Organization predicts that implementing a circular economy by 2030 might result in an additional 7-8 million jobs being created globally. However, other research has also found that the adoption of circular economy principles may lead to job losses in emerging economies.
On the other hand, implementing a circular economy in the United States has been presented by Ranta et al. who analyzed the institutional drivers and barriers for the circular economy in different regions worldwide, by following the framework developed by Scott R. In the article, different worldwide environment-friendly institutions were selected, and two types of manufacturing processes were chosen for the analysis (1) a product-oriented, and (2) a waste management. Specifically, in the U.S., the product-oriented company case in the study was Dell, a US manufacturing company for computer technology, which was the first company to offer free recycling to customers and to launch to the market a computer made from recycling materials from a verified third-party source. Moreover, the waste management case that includes many stages such as collection, disposal, recycling in the study was Republic Services, the second-largest waste management company in the US. The approach to defining the drivers and barriers was to first identify indicators for their cases in study and then to categorize these indicators into drivers when the indicator was in favor of the circular economy model or a barrier when it was not.
On 2 March 2022 in Nairobi, representatives of 175 countries pledged to create a legally binding agreement to end plastic pollution by the end of the year 2024. The agreement should address the full lifecycle of plastic and propose alternatives including reusability. The agreement is expected to facilitate the transition to a circular economy that will reduce GHG emissions by 25 percent, according to the published statement.
It is estimated that the waste sector can achieve net zero emissions in the coming decades by improving and adopting circular approaches to municipal solid waste systems. Circularity is growing in national focus. It was one focus of the 2024 COP 29 United Nations Climate Conference hosted in Baku, Azerbaijan. During the annual conference, a Joint Resolution declaring the intent of the Republic of Azerbaijan to focus on global and regional collaboration focused on efficiency and circularity was established and signed.
It has been argued that emerging technologies should be designed with circular economy principles from the start, including solar panels.
Recycling should therefore "reduce environmental impacts of the overall product/service provision system assessed based on the life-cycle assessment approach".
One study suggests that "a mandatory certification scheme for recyclers of electronic waste, in or out of Europe, would help to incentivize high-quality treatment processes and efficient material recovery".
Digitalization may enable more efficient corporate processes and minimize waste.
Circular business models, as the economic model more broadly, can have different emphases and various objectives, for example: extend the life of materials and products, where possible over multiple 'use cycles'; use a 'waste = food' approach to help recover materials, and ensure those biological materials returned to earth are benign, not toxic; retain the embedded energy, water, and other process inputs in the product and the material for as long as possible; Use systems-thinking approaches in designing solutions; regenerate or at least conserve nature and living systems; push for policies, taxes and market mechanisms that encourage product stewardship, for example 'polluter pays' regulations.
Circular business models are enabled by circular supply chains. In practice, collaboration for circular supply chains can enable the creation, transfer, and/or capture of value stemming from circular business solutions. Collaboration in supply chains can extend to downstream and upstream partners, and include existing and new collaboration. Similarly, circular supply chain collaboration allows innovation into the circular business model, focusing on its processes, products, or services.
In 2020, PACE released a report with partner Circle Economy claiming that the world is 8.6% circular, claiming all countries are "developing countries" given the unsustainable levels of consumption in countries with higher levels of human development.
PACE is a coalition of CEOs and Ministers—including the leaders of global corporations like IKEA, Coca-Cola, Alphabet Inc., and DSM, governmental partners and development institutions from Denmark, The Netherlands, Finland, Rwanda, UAE, China, and beyond. Initiatives currently managed under PACE include the Capital Equipment Coalition with Philips and numerous other partners and the Global Battery Alliance with over 70 partners. In January 2019, PACE released a report entitled "A New Circular Vision for Electronics: Time for a Global Reboot" (in support of the United Nations E-waste Coalition).
The coalition is hosted by a Secretariat headed by David B. McGinty, former leader of the Human Development Innovation Fund and Palladium International, and board member of BoardSource. Board Members include Inger Andersen, Frans van Houten, Ellen MacArthur, Lisa P. Jackson, and Stientje van Veldhoven.
Strategic management is the field of management that comes to the rescue allowing companies to carefully evaluate CE-inspired ideas, but also to take a firm apart and investigate if/how/where seeds of circularity can be found or implanted. Prior research has identified strategic development for circularity to be a challenging process for companies, demanding multiple iterative strategic cycles. The book Strategic Management and the Circular Economy defined for the first time a CE strategic decision-making process, covering the phases of analysis, formulation, and planning. Each phase is supported by frameworks and concepts popular in management consulting—like Concept map, value chain, VRIO, Porter's five forces, PEST analysis, SWOT analysis, strategic clock, or the internationalization matrix—all adapted through a CE lens, hence revealing new sets of questions and considerations. Although yet to be verified, it is argued that all standard tools for strategic management can and should be calibrated and applied to a CE. A specific argument has already been made for the strategy direction matrix of product vs market and the 3 × 3 GE-McKinsey matrix to assess business strength vs industry attractiveness, the BCG matrix of market share vs industry growth rate, and Kraljic's portfolio matrix.
Complex and certified engineering systems, however, include many of the smaller products encountered on a daily basis, for example bicycles and household appliances. Implementing the principles of circularity requires all engineering design teams to take a lifecycle approach to the product.
As with the traditional engineering lifecycle, this approach can be applied to all engineering systems, with the depth of activity tailored depending on the complexity of the product. and can incorporate multiple inter requiring planning, substantial resource consumption, and prolonged service lifetimes.
The matrix captures the value stream for various suppliers, providing increasing levels of complexity in products and services. It is important to note that these suppliers will change throughout the life cycle. In the design phase of the complex engineering system, traditionally, the system-level suppliers would only be those suppliers who are integrating the engineering system itself. Later in the life cycle, the initial systems-level suppliers will be joined by other suppliers operating at a systems level, who may deliver products and services that facilitate the operation and usage of the initial engineering system.
The primary challenge within organizations will be a mindset shift and establishment of these innovative methodologies. Despite these hurdles, the implementation of this engineering lifecycle approach holds enormous potential for both consumers and businesses. This is especially true when a collaborative, through-life service approach is applied, highlighting the vast economic opportunities that can arise from embracing circularity in engineering lifecycles.
A circular textile economy is in response to the current linear model of the fashion industry, "in which raw materials are extracted, manufactured into commercial goods, and then bought, used, and eventually discarded by consumers" (Business of Fashion, 2017). 'Fast fashion' companies have fueled the high rates of consumption which further magnify the issues of a linear system. "The take-make-dispose model not only leads to an economic value loss of over $500 billion per year but also has numerous negative environmental and societal impacts" (Business of Fashion, 2018). Such environmental effects include tons of clothing ending up in landfills and incineration, while the societal effects put human rights at risk. A documentary about the world of fashion, The True Cost (2015),Ross, M (Producer), & Morgan, A (Director). (2015, May). The true cost Motion. United States: Life is My Movie Entertainment. explained that in fast fashion, "wages, unsafe conditions, and factory disasters are all excused because of the needed jobs they create for people with no alternatives." This shows that fast fashion is harming the planet in more ways than one by running on a linear system.
It is argued that by following a circular economy, the textile industry can be transformed into a sustainable business. A 2017 report, "A New Textiles Economy",Ellen MacArthur Foundation, A new textiles economy: Redesigning fashion's future, (2017, http://www.ellenmacarthurfoundation.org/publications ). stated the four key ambitions needed to establish a circular economy: "phasing out substances of concern and microfiber release; transforming the way clothes are designed, sold, and used to break free from their increasingly disposable nature; radically improving recycling by transforming clothing design, collection, and reprocessing; and making effective use of resources and moving to renewable input." While it may sound like a simple task, only a handful of designers in the fashion industry have taken charge, including Patagonia, Eileen Fisher, Nathalia JMag, and Stella McCartney. An example of a circular economy within a fashion brand is Eileen Fisher's Tiny Factory, in which customers are encouraged to bring their worn clothing to be manufactured and resold. Similar initiatives are also found in Europe, where outdoor garment companies facilitate a textile return systems that encourage customers to bring back used garments for repair, redesign, resale, or recycling In a 2018 interview,The Glossy Podcast. (2018, May 30). Eileen Fisher on 34 years in sustainable fashion: "It's about constantly learning"
Circular initiatives, such as clothing rental start-ups, are also getting more and more highlight in the EU and in the US as well. Operating with circular business model, rental services offer everyday fashion, baby wear, maternity wear for rent. The companies either offer flexible pricing in a 'pay as you rent' model like Palanta does, or offer fixed monthly subscriptions such as Rent The Runway or Le Tote.
Research on the circular economy has highlighted the role of the informal sector in extending product life cycles. An Indian researcher from the Indian Institutes of Technology (IIT) has shown that street vendors contribute significantly to circular economy practices through the refurbishment and resale of second-hand clothing. However, the primary motivation for these vulnerable groups is not environmental sustainability, but livelihood generation. This phenomenon has been conceptualized as a livelihood-driven circular economy within the textile industry.
Both China and Europe have taken the lead in pushing a circular economy. McDowall et al. 2017 stated that the "Chinese perspective on the circular economy is broad, incorporating pollution and other issues alongside waste and resource concerns, while Europe's conception of the circular economy has a narrower environmental scope, focusing on waste and resources and opportunities for business".
Construction is very important to the economy of the European Union and its state members. It provides 18 million direct jobs and contributes to about 9% of the EU's GDP. The main causes of the construction's environmental impact are found in the consumption of non-renewable resources and the generation of contaminant residues, both of which are increasing at an accelerating pace. In the European Union alone, people and companies generate more than 2 billion tonnes of garbage year, or 4.8 tonnes per person, mostly from the building, mining, and manufacturing sectors. Each individual in Europe generates half a tonne of municipal garbage annually, less than half of which gets recycled.
Cement production accounts for 2.4% of worldwide CO2 emissions from industrial and energy sources.
Decision making about the circular economy can be performed on the operational (connected with particular parts of the production process), tactical (connected with whole processes) and strategic (connected with the whole organization) levels. It may concern both construction companies as well as construction projects (where a construction company is one of the stakeholders).
Urban decay can be deconstructed, hereby creating new construction elements that can be used for creating new buildings and Land recycling.
Modular construction systems can be useful to create new buildings in the future, and have the advantage of allowing easier deconstruction and reuse of the components afterwards (end-of-life buildings).
Another example that fits the idea of circular economy in the construction sector on the operational level, there can be pointed walnut husks, that belong to hard, light and natural abrasives used for example in cleaning brick surfaces. Abrasive grains are produced from crushed, cleaned and selected walnut shells. They are classified as reusable abrasives. A first attempt to measure the success of circular economy implementation was done in a construction company. The circular economy can contribute to creating new posts and economic growth. According to Gorecki, one of such posts may be the Circular economy manager employed for construction projects.
Some car manufacturers such as Volvo are also looking at alternative ownership models (leasing from the automotive company; "Care by Volvo"). Riding the wave of change in the automotive industry with circular economy
Research related to the Dutch industry shows that 25% of the Dutch companies are knowledgeable and interested in a circular economy; furthermore, this number increases to 57% for companies with more than 500 employees. Some of the areas are chemical industries, wholesale trade, industry and agriculture, forestry and fisheries because they see a potential reduction of costs when reusing, recycling and reducing raw materials imports. In addition, logistic companies can enable a connection to a circular economy by providing customers incentives to reduce costs through shipment and route optimization, as well as, offering services such as prepaid shipping labels, smart packaging, and take-back options. The shift from linear flows of packaging to circular flows as encouraged by the circular economy is critical for the sustainable performance and reputation of the packaging industry. The government-wide program for a circular economy is aimed at developing a circular economy in the Netherlands by 2050.
Several statistics have indicated that there will be an increase in freight transport worldwide, which will affect the environmental impacts of the global warming potential causing a challenge to the logistics industry. However, the Dutch council for the Environment and Infrastructure (Dutch acronym: Rli) provided a new framework in which it suggests that the logistics industry can provide other ways to add value to the different activities in the Dutch economy. Examples of adding value in innovative ways to the Dutch economy are an exchange of resources (either waste or water flows) for production from different industries and changing the transit port to a transit hub concept. The Rli studied the role of the potentials of the logistics industry for three sectors, agriculture and food, chemical industries and high tech industries.
These risks can be mitigated by addressing three specific issues that will also depend on the local context. These are contaminant monitoring, collection, transport, and treatment, and regulation and policy.
The Netherlands, aiming to have a completely circular economy by 2050, intends a shift to circular agriculture as part of this plan. This shift plans on having a "sustainable and strong agriculture" by as early as 2030. Changes in the Dutch laws and regulations will be introduced. Some key points in this plant include:
The EU has seen a huge potential for implementing a circular economy in the furniture sector. Currently, out of 10,000,000 tonnes of annually discarded furniture in the EU, most of it ends up in landfills or is incinerated. There is a potential increase of €4.9 billion in Gross Value Added by switching to a circular model by 2030, and 163,300 jobs could be created.
A study about the status of Danish furniture companies' efforts on a circular economy states that 44% of the companies included maintenance in their business models, 22% had take-back schemes, and 56% designed furniture for recycling. The authors of the study concluded that although a circular furniture economy in Denmark is gaining momentum, furniture companies lack knowledge on how to effectively transition, and the need to change the business model could be another barrier.
Another report in the UK saw a huge potential for reuse and recycling in the furniture sector. The study concluded that around 42% of the bulk waste sent to landfills annually (1.6 million tonnes) is furniture. They also found that 80% of the raw material in the production phase is waste.
Organizations such as Zero Waste Scotland have conducted studies to identify areas with reuse potential, allowing equipment to continue life in other industries, or to be redeployed for oil and gas.
What gives entities the ability to achieve 'net zero' carbon-emissions, is that they can offset their fossil fuel consumption by removing carbon from the atmosphere. While this is a necessary first step, global smart grid technologist, Steve Hoy, believes that in order to create a circular economy we should adapt the concept of 'True Zero' as opposed to 'net zero', which is eliminating fossil fuel consumption entirely so that all energy is produced from renewable sources.
Current growth projections in the renewable energy industry expect a significant amount of energy and raw materials to manufacture and maintain these renewable systems. "Due to the emissions attributed to fossil-fuel electricity generation, the overall carbon footprint of renewable energy technologies is significantly lower than for fossil-fuel generation over the respective systems lifespan." However, there are still linear trajectories when establishing renewable energy systems that should be assessed in order to fully transition to a circular economy.
A study estimates losses of 61 metals, showing that use spans of, often scarce, tech-critical metals are short. A study using Project Drawdown's modeling framework indicates that, even without considering costs or bottlenecks of expansion of renewable energy generation, metal recycling can lead to significant climate change mitigation.
On 17 December 2012, the European Commission published a document entitled "Manifesto for a Resource Efficient Europe".
In July 2014, a zero-waste program for Europe has been put in place aiming at the circular economy. Since then, several documents on this subject have been published. The following table summarizes the various European reports and legislation on the circular economy that have been developed between 2014 and 2018.
In addition to the above legislation, the EU has amended the Eco-design Working Plan to add circularity criteria and has enacted eco-design regulations with circular economy components for 7 product types (refrigerators, dishwashers, electronic displays, washing machines, welding equipment and servers and data storage products). These eco-design regulations are aimed at increasing the reparability of products by improving the availability of spare parts and manuals. At the same time, the European research budget related to the circular economy has increased considerably in the last few years: it has reached 964 million euros between 2018 and 2020. In total, the European Union has invested 10 billion euros on Circular Economy projects between 2016 and 2019.
One waste atlas aggregates some data about waste management of countries and cities, albeit the data is very limited.
The "Circularity Gap Report" indicates that "out of all the minerals, biomass, fossil fuels and metals that enter the world economy, only 8.6 percent are reused".
The European Commission's Circular Economy Action Plan has resulted in a wide range of projects, with an emphasis on waste and material sustainability, as well as the circularity of consumer items. Despite a huge number of EU legislative measures, the European Union's circularity rate was 11.5% in 2022 and is slowing down currently.
The European environmental research and innovation policy aims at supporting the transition to a circular economy in Europe, defining and driving the implementation of a transformative agenda to green the economy and the society as a whole, to achieve a truly sustainable development. Research and innovation in Europe are financially supported by the program Horizon 2020, which is also open to participation worldwide.See Horizon 2020 – the EU's new research and innovation programme: http://europa.eu/rapid/press-release_MEMO-13-1085_en.htm Circular economy is found to play an important role to economic growth of European Countries, highlighting the crucial role of sustainability, innovation, and investment in no-waste initiatives to promote wealth.
The European Union plans for a circular economy are spearheaded by its 2018 Circular Economy Package. Historically, the policy debate in Brussels mainly focused on waste management which is the second half of the cycle, and very little is said about the first half: eco-design. To draw the attention of policymakers and other stakeholders to this loophole, the Ecothis, an EU campaign was launched raising awareness about the economic and environmental consequences of not including eco-design as part of the circular economy package.
In 2020, the European Union released its Circular Economy Action Plan.
The Action plan was also a way to integrate a policy framework, an integration of existing policies and legal instruments. It includes notably some amendments. As a matter of fact, the implementation of this new plan was supported by the European Economic and Social Committee (EESC). This support included in-depth consultation.European Economic and Social Committee (2017). Circular Economy : One year after adoption, working together for the future (s. d.).

Other notable countries are Italy, the United Kingdom, Austria, Slovenia, and Denmark.
Outside the EU, countries such as Brazil, China, Canada, the United States and especially Japan are working on the shift towards it.
Most countries that are in the lead in the field of circular economy are European countries, meaning that Europe in general is in the lead group at the moment. The reasons behind this are numerous. First of all, circular economy is a field that is, at the moment mostly advanced in the developed countries, thanks to, between others, technology. The efforts of the European Commission are also non negligible, with documents such as the Commission staff working document "Leading the way to a global circular economy: state of play and outlook" or the new action plan for circular economy in Europe, being one of the main blocs of the green deal.
Even if Europe as a whole is a good actor in the field, some European countries are still struggling to make the shift faster. These countries are mostly the eastern European countries (Romania, Hungary, Bulgaria, Slovakia, etc.) but also in some fields Portugal, Greece, Croatia and even Germany.
In 2018, the newspaper Politico made a ranking of the (by then) 28 European countries by making an aggregation of the seven key metrics of the commission for each country. The advantage here is that it gives a general view of how countries work towards circular development and how they compare to each other but the main drawback is that, as mentioned in the article, the seven metrics all have equal weight and importance in Politico's calculations, which is not the case in real life. Indeed, it is said in the same article that the countries that score the highest in CE are not necessarily the greenest according to the Environmental Performance Index. For example, Germany, which scores 1st in the Politico ranking, only scores 13th worldwide in the EPI and is behind 10 European countries.
Policymakers' views expanded from a focus on recycling to broad efforts to promote efficiency and closed-loop flows of materials at all stages, from production to distribution to consumption. As part of its efforts to enhance the circular economy, China is attempting to decrease its reliance on mining for its mineral supply. Academic Jing Vivian Zhan writes that promoting the circular economy helps China to avoid the resource curse and helps to alleviate overreliance on extractive industries.
A major barrier to achieving a circular economy in China is poor enforcement of regulation, particularly at lower levels of government.
Since 2020, Europe's new green deal plan focuses on "design and production from the perspective of the circular economy", its main objective is to ensure that the European economy keeps these resources as long as possible.
The action plan of this circular development is mainly based on different objectives. They are:
From 2019 to 2023, the European Investment Bank funded €3.83 billion to co-finance 132 circular economy initiatives across many industries. Circular economy initiatives with a higher risk profile have secured finance through risk-sharing instruments and EU guarantees.
The Luxembourg added in 2019 Circular economy in their data-driven innovation strategy, considering it now as a crucial field for innovation in the next years. It is present in most sectors of the country's development plan even if it is still only at the beginning of its development.
More initiatives are starting to emerge, however, to develop better in the field:
In 2024, the Scottish Parliament passed the Circular Economy (Scotland) Act 2024, which would require the setting of targets and providing updates to the strategy to achieve those targets as frequently as 5 years or more frequently than that.
In 2023, the Senedd banned single use plastics, which would require the setting of targets and providing updates to the strategy to achieve those targets as frequently as 5 years or more frequently than that.
The European Circular Bioeconomy Fund invests in early-stage companies with developed innovations that are searching for funds to broaden their activities and reach new markets. It specifically invests in:
Corvellec and Stål (2019) are mildly critical of apparel manufacturing circular economy take-back systems as ways to anticipate and head off more severe waste reduction programs:
Research by Zink and Geyer (2017: 593) questioned the circular economy's engineering-centric assumptions: "However, proponents of the circular economy have tended to look at the world purely as an engineering system and have overlooked the economic part of the circular economy. Recent research has started to question the core of the circular economy—namely, whether closing material and product loops do, in fact, prevent primary production."
There are other critiques of the circular economy (CE). For example, Allwood (2014) discussed the limits of CE 'material circularity', and questioned the desirability of CE in a reality with growing demand. The problem CE overlooks is how displacement is governed mainly by market forces, according to McMillan et al. (2012). It's the tired old narrative, that the invisible hand of market forces will conspire to create full displacement of virgin material of the same kind, said Zink & Geyer (2017). Korhonen, Nuur, Feldmann, and Birkie (2018) argued that "the basic assumptions concerning the values, societal structures, cultures, underlying world-views and the paradigmatic potential of CE remain largely unexplored".
It is also often pointed out that there are fundamental limits to the concept, which are based, among other things, on the laws of thermodynamics. According to the second law of thermodynamics, all spontaneous processes are irreversible and associated with an increase in entropy. It follows that in a real implementation of the concept, one would either have to deviate from the perfect reversibility in order to generate an entropy increase by generating waste, which would ultimately amount to still having parts of the economy which follow a linear scheme, or enormous amounts of energy would be required (from which a significant part would be dissipated in order to for the total entropy to increase). In its comment to concept of the circular economy the European Academies' Science Advisory Council (EASAC) came to a similar conclusion:
In addition to this, the circular economy has been criticized for lacking a strong social justice component. Indeed, most circular economy visions, projects and policies do not address key social questions regarding how circular economy technologies and solutions will be controlled and how their benefits and costs will be distributed. To respond to these limitations some academics and social movements prefer to speak of a circular society rather than a circular economy. They thereby advocate for a circular society where knowledge, political power, wealth, and resources are sustainably circulated in fundamentally democratic and redistributive manners, rather than just improving resource efficiency as most circular economy proposals do.
Moreover, it has been argued that a post-growth approach should be adopted for the circular economy where material loops are put (directly) at the service of wellbeing, instead of attempting to reconcile the circular economy with GDP growth. For example, efficiency improvements at the level of individual products could be offset by a growth in total or per-capita consumption, which only beyond-circularity measures like choice editing and rationing unsustainable products or emissions may be able to address.
In their namesake 2010 book, former Ecover CEO and Belgian entrepreneur Gunter Pauli uses the term blue economy to refer to the societal shift to using materials of local abundance, choosing low-energy processes, and seeking to create revenue streams from each process step.
/ref> Today, the climate emergency and environmental challenges induce companies and individuals in rethink their production and consumption patterns. The circular economy is framed as one of the answers to these challenges. Key macro-arguments in favour of the circular economy are that it could enable economic growth that does not add to the burden on natural resource extraction but decouples resource uses from the development of economic welfare for a growing population, reduces foreign dependence on critical materials, lowers CO2 emissions, reduces waste production, and introduces new modes of production and consumption able to create further value. Corporate arguments in favour of the circular economy are that it could secure the supply of raw materials, reduce the price volatility of inputs and control costs, reduce spills and waste, extend the life cycle of products, serve new segments of customers, and generate long-term shareholder value. A key idea behind the circular business models is to create loops throughout to recapture value that would otherwise be lost.

The main goal being in this respect to lead to the development of a framework conducive to the circular economy. In addition, the development of this Action Plan was also intended to enable the development of a new market for secondary raw materials. Concretely, here are the principal areas concerned by the Action Plan:

Europe's green deal, which came into being in 2019, aims at a climate-neutral circular economy. For this, a distinct difference between economic growth and resources will be found. "A circular economy reduces the pressure on natural resources and is an indispensable prerequisite for achieving the goal of climate neutrality by 2050 and halting biodiversity loss."
