The circular economy has great potential to help meet global sustainability targets and the Paris Agreement's goals in particular. The built environment, consuming almost half of the world's resources extracted every year and responsible for a massive environmental footprint, is a fundamental sector in the circular transition.

Moving towards a circular built environment involves a shift in roles and business models for stakeholders active in this sector. However, barriers related to culture, regulations, market, technology and education are slowing down the transition.

The private and public sector need to create a level playing field in order for circular materials, products and services to become the new normal in the built environment. This requires bold leadership from both companies and policy-makers who have to transform the market (e.g. by introducing new valuation methods) and implement long-term policies that encourage the scaling of circular solutions (e.g. through circular procurement). Standardization, new forms of collaboration and co-creation processes are essential elements in the transition. Digital innovation, education and information sharing can further drive the change in mindset and culture that is needed to turn the circular built environment into reality.

The Circularity Gap Report 2019 finds that the global economy is only 9% circular - just 9% of the 92.8 billion tonnes of minerals, fossil fuels, metals and biomass that enter the economy are re-used annually. Climate change and material use are closely linked. Circle Economy calculates that 62% of global greenhouse gas emissions (excluding those from land use and forestry) are released during the extraction, processing and manufacturing of goods to serve society’s needs; only 38% are emitted in the delivery and use of products and services.

It highlights the vast scope to reduce greenhouse gas emissions by applying circular principles - re-use, re-manufacturing and re-cycling - to key sectors such as the built environment. Yet it notes that most governments barely consider circular economy measures in policies aimed at meeting the UN target of limiting global warming to 1.5°C above pre-industrial levels.

This report thus highlights three key circular strategies which could be adapted throughout the economy to help limit global warming and gives examples:

1. Optimising the utility of products by maximising their use and extending their lifetime. Ridesharing and carsharing already make it less important to own a car. Autonomous driving will accelerate this trend, potentially increasing the usage of each vehicle by a factor of eight. At the same time electric powertrains, intelligent maintenance programmes and software integration can enhance the lifetime of cars.
2. Enhanced recycling, using waste as a resource. By 2050 there will be an estimated 78 million tonnes of decommissioned solar panels. Modular design would enable products to be easily disassembled, components to be re-used and valuable materials to be recovered to extend their economic value and reduce waste.
3. Circular design, reducing material consumption and using lower-carbon alternatives. Bamboo, wood and other natural materials have the potential to reduce dependence on carbon-intensive materials such as cement and metals in construction. Instead of emitting carbon, these materials store it and will last for decades. They can be burnt to generate energy at the end of their life.

The report also provides recommendations for governments: while The Netherlands has set itself a target of becoming 50% circular by 2030 and 100% by 2050, most governments have yet to wake up to the potential of the circular economy. The report recommends joining up climate change and circular economy strategies to achieve maximum impact, through the use of tax and spending plans to drive change. They should:

• Abolish financial incentives which encourage overuse of natural resources, such as subsidies for fossil fuel exploration, extraction and consumption;
• Raise taxes on emissions, excessive resource extraction and waste production, for example by implementing a gradually increasing carbon tax;
• Lower taxes on labour, knowledge and innovation and invest in these areas. Lower labour taxes will encourage labour-intensive parts of a circular economy such as take-back schemes and recycling.

The Relooping Fashion Initiative (2015-2017) was aimed at piloting and modelling the circular business ecosystem for textiles. This report covers the business ecosystem modelling work and introduces the project team’s crystallized vision of a higher-level system that enables the textiles industry to operate according to the basic principles of a circular economy. 

The focus of the report is on explaining the principles of a circular economy in the context of textiles, and drawing a picture of the key material flows and types of actors along the value cycles from end-user back to end-user. The overall goal is to maintain the value of materials as high as possible, with minimum environmental impact. The different circular business models for textiles are introduced along the value cycles. The report covers 1) repair and maintenance, 2) re-use as product, 3) re-use as material, and 4) recycling-related activities, and business models for post-consumer/user textiles along the entire value chain.

All these processes need to work seamlessly together for the circular business ecosystem to function effectively. New recycling technologies are crucial to solving the global textile waste problem, and to be able to replace some of the virgin materials such as cotton with recycled textile materials. The report also discusses the topic of shared value creation in the circular economy context.

Circular Economy and Employment first summarizes the main definitions and conceptualisations of a circular economy, then clarifies the relationship to related concepts such as green growth and eco-innovation. This report is the outcome of a project estimating the employment effects of a circular economy.

The Circular Economy mainly focuses on savings on the shares of material, labour, energy, and capital embedded in the product. In finite systems it is intended to “design out waste”. An important difference is made between consumables (one or few time usage) and durables (years of usage) products. Material savings can be achieved by already established recycling and remanufacturing activities finally aiming at a “zero waste economy”. More recently, the contribution of green ICT leading to less material inputs (“digital revolution”, e.g. photos are no longer printed but distributed by e-mail or social media), a general greater importance of services, the evolution of the sharing economy (e. g. car sharing) or a higher utilisation rate for products for the circular economy are discussed.

Detailed concepts of green growth from OECD, UNEP, EEA and the Global Green Growth Institute are also considered. Green growth means fostering economic growth and development while ensuring that natural assets continue to provide the resources and environmental services on which our well-being relies. Investment and (eco-) innovation activities shall give rise to new, more sustainable sources of growth and development. Moving towards a circular economy may be understood as a tool to achieve a green economy, a circular economy is one of the main elements helping to achieve the greening of an economy.

The workbook 'Organising for the Circular Economy - A Workbook for Developing Circular Business Models' supports companies and other organisations that aim to become circular by providing a unique model that highlights the various building blocks of circular business models.

A concrete step-by-step approach allows organisations to work on the development of their own circular business model. To clarify and inspire, a set of infographics displaying the cycles of 30 front-runner organisations from the Netherlands, which already actively incorporate circularity in their business operations, is provided alongside the workbook.

The workbook and infographics can be downloaded free of charge from this website.

Is the current circular economy paradigm enough? Will it get us to a fairer society and flourishing planet? Will it allow us to meet the UN's Sustainable Development Goals? Perhaps not. There could be a different way: by combining social enterprise and circular economy (= social circular economy), to deliver benefits to people, planet and profit.

​The Social Circular Economy report provides insights from our engagement with 30+ organisations from around the world that are using the value creating approaches of the circular economy to deliver environmental, societal and economic benefits. From a recycling hub supporting a disability rehabilitation centre to corporate uniform repurposing with women's collectives, there are organisations innovating business models and processes to do business better and help meet UN Sustainable Development Goals. This report covers:

• What is the social circular economy?
• What are the themes across social circular enterprises?
• What are examples of these organisations?
• How can you or your organisation participate?

Food packaging facilitates storage, handling, transport, and preservation of food and is essential for preventing food waste. In the existing economic system, food packaging is generally designed for single-use and discarded after relatively short periods of time, a scheme that is no longer acceptable in the transition to a circular economy.

This paper offers a detailed analysis in food packaging materials with respect to properties, recycling, and contaminants. It also discusses different approaches such as weight reduction versus recyclability or deposit and reuse schemes for permanent material-based food packaging.

Achieving the 2030 UN Sustainable Development Goals and Paris Agreement climate targets will hinge upon the global transition to a low-carbon circular economy. Replacing finite and fossil-based materials with responsibly managed renewable materials could decrease carbon emissions whilst reducing dependency on finite resources.

However, the role that renewable materials can play in the circular economy is often under-rated, and, so far, most of the conversation has focussed on biodegradability, instead of the role they could play in reuse, remanufacturing, and recycling streams. The aim of the Collaborative Project was to start a conversation on the role of renewables in the circular economy, and in order to do this, set out the opportunities and challenges that companies face when using/shifting to renewable materials today and propose a shared vision for the future.
