File:Towards a Circular City.webm Circular economy is an economic system aimed at eliminating waste and the continual use of resources. Circular systems employ reuse, sharing, repair, refurbishment, remanufacturing and recycling to create a closed-loop system, minimizing the use of resource inputs and the creation of waste, pollution, and carbon emissions. The circular economy aims to keep products, equipment, and infrastructure in use for longer, thus improving the productivity of these resources. All 'waste' should be seen as a resource.

Principles

The principles of the circular economy can be summarized into three key points:

1. Design out waste and pollution: By rethinking how resources are used, products and processes can be designed from the outset to minimize waste and pollution.
2. Keep products and materials in use: This involves designing for durability, reuse, remanufacturability, and recyclability to keep materials circulating in the economy.
3. Regenerate natural systems: The circular economy seeks not only to minimize negative impacts but to have a positive effect on the environment through practices that restore and regenerate natural systems.

Benefits

The circular economy offers several benefits, including reducing pressure on the environment, improving the security of the supply of raw materials, increasing competitiveness, stimulating innovation, boosting economic growth, and creating jobs. It also provides a way to tackle climate change by lowering carbon emissions and optimizing resource efficiency.

Implementation

Implementing the circular economy requires changes across the board: from product design and manufacturing processes to new business and market models, from new ways of delivering services to new consumer behaviors. It involves stakeholders across the value chain, including manufacturers, consumers, policymakers, and those involved in waste management and recycling.

Challenges

Transitioning to a circular economy also presents challenges, such as the need for large-scale redesign of processes and products, development of new materials, and changes in consumer behavior. There are also economic and regulatory hurdles, as well as the need for investment in new technologies and infrastructure.

Examples

Examples of circular economy practices include:

• Product as a Service (PaaS) models, where consumers lease or rent products instead of owning them outright, encouraging manufacturers to design for longevity and easy maintenance.
• Industrial symbiosis, where waste or by-products of one industry become the raw materials for another.
• Comprehensive recycling and upcycling programs that transform waste materials into new products.
