Background Studies

The circular economy is an economic model that aims to eliminate waste and promote the continuous use of resources through closed-loop systems. It is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. The circular economy is relevant to sustainable water, energy, and food systems because it promotes the efficient and effective use of resources, reduces waste, and enhances resilience to environmental and social challenges. By keeping materials and products in use, the circular economy can help to conserve natural resources, reduce greenhouse gas emissions, and protect biodiversity. It can also create new economic opportunities, such as through the development of innovative technologies and business models that promote resource efficiency and circularity.

China has been promoting the concept of circular economy since the early 2000s, recognizing its potential to contribute to sustainable development and address environmental challenges. In 2002, the Chinese government launched the “Circular Economy Development Strategy and Promotion Plan,” which set targets for increasing resource efficiency, reducing waste, and promoting the recycling and reuse of materials. Since then, China has implemented a range of policies and initiatives to promote circular economy practices, including the establishment of circular economy pilot zones, the development of circular economy industrial parks, and the introduction of regulations and incentives to support resource recycling and waste reduction. The government has also emphasized the importance of eco-design, green procurement, and product stewardship in promoting circularity.

In recent years, China has further strengthened its circular economy policies, with a focus on promoting a “green” and “low-carbon” economy. In 2020, the Chinese government released a new Circular Economy Development Plan (2021-2025), which sets targets for improving resource efficiency, promoting green manufacturing, and reducing pollution and emissions. The plan also emphasizes the need to integrate circular economy principles into the water, energy, and food sectors to promote sustainable development.

The Water-Energy-Food Nexus in China

Circular economy principles can be applied to water, energy, and food systems in China to achieve sustainable development. Water, energy, and food are interdependent systems, with water required for food and energy production, and energy needed for water treatment and distribution. At the same time, the production and consumption of energy and food have significant impacts on water quality and availability. In China, the rapid development of the economy and population growth have put enormous pressure on the country’s water, energy, and food systems. As a result, China is facing challenges related to water scarcity, air and water pollution, soil degradation, and climate change. The circular economy approach can help to address these challenges by promoting resource efficiency, waste reduction, and sustainable consumption and production.

China’s water, energy, and food systems are interdependent and heavily influenced by natural resource availability and climate conditions. Water is essential for agricultural irrigation, hydropower generation, and industrial and domestic uses. Energy is required for water extraction, treatment, and distribution, as well as for agricultural mechanization, transportation, and industrial production. Food production is dependent on water and energy inputs, while food processing and distribution require substantial energy and water resources. The nexus between water, energy, and food systems in China is complex and poses significant challenges for sustainable development.

The water-energy-food nexus in China faces a number of challenges, including:

• China is one of the world’s most water-scarce countries, with per capita water resources well below the global average. Rapid economic growth and urbanization have put additional pressure on water resources, making it increasingly difficult to meet demand for agriculture, industry, and domestic use.
• Energy security has resulted in high levels of air pollution, which in turn has negative impacts on public health and the environment. The government is seeking to diversify its energy mix by promoting renewable energy sources, but this transition poses challenges in terms of energy storage and grid integration.
• China has experienced a number of high-profile food safety scandals in recent years, which have eroded public trust in the food system. Ensuring food safety and security is a major challenge, particularly in light of climate change impacts on crop yields and quality.
• China is highly vulnerable to the impacts of climate change, which are likely to exacerbate existing challenges in the water-energy-food nexus. Adaptation measures will be needed to mitigate these impacts and ensure that the water, energy, and food systems remain resilient in the face of changing conditions.

Despite these challenges, there are also opportunities for managing the water-energy-food nexus in a more sustainable and integrated manner. For example;

• Improving resource efficiency can help to reduce pressure on water, energy, and food resources, and can also contribute to greenhouse gas emissions reductions. This can be achieved through measures such as water-efficient irrigation, energy-efficient buildings, and reduced food waste.
• China has made significant strides in promoting renewable energy, particularly in the areas of wind and solar power. Continued investment in renewable energy sources can help to reduce reliance on coal and other fossil fuels, while also reducing greenhouse gas emissions.
• Promoting sustainable agriculture practices, such as conservation tillage and agroforestry, can help to reduce soil erosion, improve soil health, and increase resilience to climate change impacts.
• Improving cross-sectoral cooperation and coordination can help to promote integrated management of the water-energy-food nexus, and can also facilitate the implementation of circular economy principles. This requires effective communication and collaboration among government agencies, industry, and civil society.

Moreover, climate change is expected to have significant impacts on the water-energy-food nexus in China. Changes in precipitation patterns, temperature, and extreme weather events are projected to affect the availability and reliability of water resources, as well as energy production and infrastructure. This, in turn, will have implications for the use of water in agriculture, energy production, and other sectors. Changes in temperature and weather patterns will also affect crop yields, quality, and diversity, with potential implications for food security, trade, and consumption patterns. As a result, it is important to consider the interconnections between water, energy, and food systems when developing climate change adaptation and mitigation strategies.

However, there are also opportunities to enhance the resilience of the water-energy-food nexus to climate change through the adoption of green technologies and practices, as well as institutional and governance innovations that promote cross-sectoral cooperation and adaptive capacity. The circular economy can play an important role in this regard by promoting the efficient use of resources and reducing greenhouse gas emissions.

Overall, managing the water-energy-food nexus in a sustainable and integrated manner requires a comprehensive approach that takes into account the interdependencies and trade-offs among these three sectors. By adopting circular economy principles and promoting resource efficiency, renewable energy, sustainable agriculture, and cross-sectoral cooperation, China can make progress toward a more sustainable and resilient future.

 Circular Economy Principles and Practices

Circular economy principles aim to promote sustainable consumption and production patterns that reduce waste and increase resource efficiency. The four main principles are;

• Reduce: This principle focuses on reducing the consumption of resources by designing products and services that use fewer resources or require less energy during their lifecycle. This can include strategies such as designing products for durability, reducing packaging waste, and promoting energy-efficient technologies.
• Reuse: This principle emphasizes the importance of keeping resources in use for as long as possible, through strategies such as repairing, refurbishing, or repurposing products or materials. This can help extend the lifespan of products, reduce waste, and save resources.
• Recycle: This principle focuses on promoting the recovery and recycling of materials and products at the end of their useful life. This can include strategies such as using recycled materials in the production of new products or promoting the use of closed-loop systems where waste is used as a resource.
• Regenerate: This principle emphasizes the importance of designing systems that restore natural resources and promote the regeneration of ecosystems. This can include strategies such as promoting the use of renewable energy sources, restoring degraded land, and promoting sustainable agricultural practices.

Examples of circular economy practices in various sectors, including water, energy, and food as follows;

Water:

• Greywater reuse: Greywater is wastewater from non-toilet plumbing fixtures such as showers and sinks. Instead of disposing of it, greywater can be treated and reused for non-potable purposes such as toilet flushing and irrigation.
• Rainwater harvesting: Collecting and storing rainwater for later use can reduce the demand for freshwater resources.
• Water recycling: Treated wastewater can be recycled and reused for non-potable purposes such as irrigation, industrial processes, and toilet flushing.

Energy:

• Renewable energy: Using renewable energy sources such as wind, solar, and hydropower can reduce reliance on fossil fuels and decrease greenhouse gas emissions.
• Energy-efficient buildings: Designing and constructing buildings that are energy-efficient, such as through the use of efficient lighting and heating systems, can reduce energy consumption and costs.

Food:

• Composting: Organic waste such as food scraps and yard waste can be composted and used to enrich soil for agricultural purposes.
• Food waste reduction: Reducing food waste through better inventory management, food donation programs, and consumer education can reduce the amount of waste sent to landfills.
• Agroforestry: Combining trees and crops in the same agricultural system can provide multiple benefits, such as improving soil health, increasing biodiversity, and sequestering carbon.

The circular economy aims to create a closed-loop system where waste is minimized and resources are conserved, promoting sustainable development and a more resilient and equitable society.

Circular Economy and Water Systems in China

Circular economy principles can play a crucial role in sustainable water management by reducing water consumption and pollution, promoting water reuse, and improving water quality. The following are some examples of circular economy practices in the water sector:

• Treating and reusing wastewater for non-potable purposes, such as irrigation or industrial use, can significantly reduce water consumption and alleviate pressure on freshwater resources.
• Capturing rainwater for use in non-potable applications, such as irrigation, can reduce demand for fresh water sources and help prevent flooding.
• Implementing water-efficient technologies, such as low-flow toilets and showerheads, can significantly reduce water consumption in households and commercial buildings.
• Encouraging water conservation practices, such as fixing leaks and reducing water use in landscaping, can also reduce water demand and promote circular water management.
• Recovering nutrients from wastewater can reduce nutrient pollution in water bodies and create value-added products, such as fertilizer.
• Circular economy practices in the water sector have been shown to reduce water demand and improve water quality, as well as generate economic benefits. For example, a study conducted in Beijing found that wastewater reuse for irrigation purposes could reduce the city’s water demand by up to 17% while generating economic benefits of around RMB 11.2 billion (approximately USD 1.7 billion) per year (Zhao et al., 2019).
• Circular economy practices can also help to address water scarcity and reduce the environmental impact of water use. For example, the use of treated wastewater for irrigation can reduce the reliance on freshwater resources and reduce nutrient pollution in water bodies (Cirad, 2019).
• In addition, circular economy practices in the water sector can help to promote sustainable urban development and enhance resilience to climate change. For example, the use of green infrastructure, such as green roofs and rain gardens, can help to manage stormwater runoff and reduce the risk of urban flooding (UNEP, 2018).

Circular economy practices in water management can also lead to cost savings and job creation. For example, a study by the Ellen MacArthur Foundation found that implementing circular economy principles in water management could result in annual cost savings of up to $32 billion in the European Union by 2030. Additionally, the study found that circular economy practices could create up to 80,000 new jobs in the water sector in the EU by 2030.

In China, the circular economy is a key part of the government’s efforts to address water scarcity and pollution. The government has implemented policies to promote circular water use, such as the Circular Economy Promotion Law and the Water Pollution Prevention and Control Law. These policies aim to encourage the use of recycled and reclaimed water, as well as the implementation of water-efficient technologies.

There are also a number of circular economy initiatives in China’s water sector. For example, the Shanghai Chemical Industry Park has implemented a circular water system, which uses treated wastewater for industrial processes and cooling, as well as for the park’s green spaces. This has reduced the park’s water consumption by 40% and decreased its discharge of wastewater by 60%. Another example is the “sponge city” program, which aims to increase the permeability of urban areas to reduce flooding and improve water management. The program includes the use of green roofs, permeable pavements, and other measures to capture and reuse rainwater.

Circular Economy and Energy Systems in China

The circular economy approach can play a significant role in improving energy management in China. By reducing energy demand and promoting the use of renewable energy sources, circular economy practices can help to mitigate greenhouse gas emissions and increase energy efficiency. Some examples of circular economy practices in the energy sector include:

• Improving the energy efficiency of buildings through better insulation, efficient lighting, and the use of renewable energy sources such as solar power can significantly reduce energy consumption.
• Encouraging cooperation between industries to share energy and other resources can reduce energy waste and promote renewable energy use.
• Converting waste into energy through processes such as anaerobic digestion or incineration can help to reduce the use of fossil fuels and promote the use of renewable energy sources.
• Developing energy storage systems such as batteries or pumped hydroelectric storage can help to integrate renewable energy sources into the grid and increase energy reliability.
• Implementing smart grids that allow for more efficient energy distribution and management can help to reduce energy waste and promote renewable energy use.

According to a study by the Ellen MacArthur Foundation, adopting circular economy practices in the energy sector could reduce global greenhouse gas emissions by up to 70% by 2050, compared to business-as-usual scenarios (Ellen MacArthur Foundation, 2019).

Moreover, circular economy practices can significantly reduce greenhouse gas emissions and improve energy efficiency. By reducing waste and reusing materials and resources, less energy is needed to produce new products, and the carbon footprint of the energy sector can be minimized. According to a study by the Ellen MacArthur Foundation, transitioning to a circular economy could reduce global greenhouse gas emissions by 48% by 2050.

In China, circular economy practices in the energy sector include the use of renewable energy sources such as wind and solar power, as well as energy-efficient technologies and systems. For example, China has the world’s largest installed capacity of wind and solar power, and the country has set a goal of reaching 20% of its total energy consumption from non-fossil fuels by 2025. Additionally, China has implemented energy efficiency standards for buildings, appliances, and vehicles to reduce energy consumption and promote the use of more efficient technologies.

Circular Economy and Food Systems in China

The circular economy approach in the food sector can help to reduce waste, increase resource efficiency, and promote sustainable production and consumption. Here are some examples and data on the importance of a circular economy in food production and consumption:

According to a report by the Chinese Academy of Sciences, China wastes around 50 million tonnes of food per year, which is equivalent to the annual food consumption of a country like South Africa. Circular economy practices such as food waste reduction and recovery can help to address this issue. For example, the “Clean Plate Campaign” launched by the Chinese government in 2020 aims to reduce food waste by promoting thrift and anti-extravagance, encouraging restaurants to offer smaller portion sizes, and providing incentives for consumers to order only what they can eat.

The circular economy approach can also help to convert organic waste into valuable resources such as compost and biogas. For instance, the “Green Kitchen” project in Beijing encourages households and restaurants to separate their food waste from other waste streams and sends it to composting facilities. The compost produced is used to fertilize urban agriculture, while the biogas generated from anaerobic digestion is used to generate electricity or for cooking.

Circular economy practices can also promote sustainable agriculture by reducing the use of non-renewable resources such as synthetic fertilizers and pesticides and increasing the use of organic waste as a soil amendment. For instance, the “Integrated Agriculture and Energy System” project in Shandong province uses agricultural waste as a feedstock for biogas production, which is then used to generate electricity and heat for greenhouses. The circular economy approach can also help to reduce the environmental impact of food packaging by promoting the use of sustainable materials and designing packaging for reuse or recycling. For example, the “Zero Waste” grocery store in Beijing uses reusable containers and packaging to reduce waste from food packaging.

Circular economy practices in the food sector have the potential to reduce waste, conserve resources, and promote sustainable agriculture. For example, food waste can be converted into animal feed, compost, or energy through processes such as anaerobic digestion and composting. In addition, organic waste can be used to produce biogas, which can then be used for cooking or electricity generation.

Another circular economy practice in the food sector is the use of regenerative agriculture, which focuses on improving soil health, conserving water, and reducing greenhouse gas emissions. This can be achieved through practices such as crop rotation, cover cropping, and reduced tillage.

According to a study published in the Journal of Cleaner Production, implementing circular economy practices in the food sector can significantly reduce greenhouse gas emissions and improve resource efficiency. The study found that reducing food waste and increasing the use of renewable energy and sustainable agriculture practices could reduce greenhouse gas emissions in the food sector by up to 65%. Another study published in the same journal found that transitioning to a circular food system in Europe could reduce greenhouse gas emissions by up to 48% and create over 700,000 jobs by 2030.

Benefits of Circular Economy for Sustainable Water, Energy, and Food Systems in China

The circular economy can bring numerous benefits to sustainable water, energy, and food systems in China. Here are some of them:

• Circular economy principles such as reducing, reusing, and recycling can help reduce waste and pollution in the water, energy, and food systems. For example, wastewater can be treated and reused for agricultural irrigation, reducing water pollution and conserving freshwater resources.
• Circular economy practices can help conserve resources such as water, energy, and land. For example, composting organic waste can produce fertilizer for crops, reducing the need for chemical fertilizers and conserving energy used in their production.
• Circular economy practices such as organic farming can help improve soil health and productivity, leading to higher crop yields and improved food security.
• Circular economy practices such as renewable energy production and energy efficiency can help reduce greenhouse gas emissions, contributing to climate change mitigation.
• Circular economic practices can create new business opportunities and jobs, contributing to economic development.

Circular economy practices can also lead to a reduction in waste and pollution. By reducing the extraction of raw materials, reusing and recycling products and materials, and using renewable energy sources, the amount of waste generated and the pollution created can be significantly reduced. For example, recycling wastewater for agricultural use reduces the amount of wastewater discharged into rivers and reduces the need for chemical fertilizers, which can pollute water sources. Similarly, using renewable energy sources such as solar and wind power instead of fossil fuels can reduce greenhouse gas emissions and air pollution.

Studies have shown that implementing circular economy practices can lead to a reduction in greenhouse gas emissions, water consumption, and waste generation, while also promoting resource conservation and creating economic benefits (Ellen MacArthur Foundation, 2015). For example, a study conducted by the International Renewable Energy Agency (IRENA) found that by adopting circular economy practices in the energy sector, China could reduce its carbon dioxide emissions by up to 70% by 2050 (IRENA, 2018).

Circular economy practices can lead to the conservation of resources, which is crucial for achieving sustainable water, energy, and food systems. By reusing and recycling materials and resources, circular economy practices can reduce the need for extracting, processing and disposing of virgin resources, which can have significant environmental impacts. For example, in the water sector, rainwater harvesting and greywater reuse can reduce the need for freshwater withdrawals and can help conserve water resources. In the energy sector, energy-efficient technologies and renewable energy sources can help conserve fossil fuels and reduce greenhouse gas emissions. In the food sector, organic farming and composting can help conserve soil and water resources and reduce food waste.

Studies have shown that circular economy practices can lead to significant resource savings. For instance, a study by the Ellen MacArthur Foundation estimated that the adoption of circular economy practices in China’s construction sector could reduce the use of natural resources by 32% and reduce greenhouse gas emissions by 44% by 2050 (Ellen MacArthur Foundation, 2018). Another study by the World Wildlife Fund (WWF) found that shifting to a circular economy in China’s food system could reduce water use by 11%, reduce land use by 7%, and reduce greenhouse gas emissions by 14% by 2030 (WWF, 2018).

Circular economic practices can create new economic opportunities and stimulate economic growth by generating new jobs, industries, and markets. For example, the recycling industry and related services have the potential to create jobs and stimulate economic growth. According to a report by the Ellen MacArthur Foundation, the adoption of circular economy practices in China could create up to 32 million new jobs by 2040, in areas such as waste management, remanufacturing, and refurbishment. Furthermore, the circular economy can stimulate innovation and new business models, leading to increased competitiveness and market share for Chinese companies.

Circular economy practices can also enhance environmental and social sustainability by reducing the negative impacts of resource extraction, reducing waste and pollution, and creating opportunities for job creation and community development. By reducing reliance on finite resources, circular economy practices can also reduce the environmental impacts associated with their extraction and transportation, such as greenhouse gas emissions, air and water pollution, and land degradation. Additionally, circular economy practices can improve the social sustainability of communities by creating new jobs and economic opportunities, promoting community engagement and participation, and enhancing the resilience of local food and water systems. These benefits can contribute to a more sustainable and resilient society in China and around the world.
