Core Concepts of Circular Economy

Circular Economy: An economic system aimed at eliminating waste and promoting the continual use of resources through principles such as regeneration, retention of value, and optimization.

ISO 59004: The essential standard within the ISO 59000 family, providing terminology, framework, and principles for the circular economy.

Circular Design: An approach to product design that prioritizes longevity, repairability, and recyclability to support circular economy principles.

Waste Hierarchy: A system that ranks waste management options according to their environmental impact, prioritizing prevention, reuse, and recycling over disposal.

Systemic Thinking: Emphasizes the interconnectedness of economic, environmental, and social systems.

Value Retention: Maintaining the highest possible value of products, components, and materials throughout their lifecycle.

Resource Optimization: Maximizing the utility and efficiency of resources in production and consumption processes.

Regenerative Practices: Activities that restore, renew, or revitalize their sources of energy and materials.

Practical Applications

Closed-loop Systems: Production and consumption models in which resources are reused, recycled, or repurposed, minimizing waste and resource extraction.

Industrial Symbiosis: The exchange of materials, energy, water, and by-products between industries to create mutual value.

Product-as-a-Service: A business model where products are offered as services rather than sold as goods, promoting shared use and extended product lifecycles.

Upcycling: Transforming by-products, waste materials, or unwanted products into new materials or products of better quality or environmental value.

Downcycling: Converting materials into new products of lesser quality and reduced functionality.

Cradle-to-Cradle: A design approach that models human industry on nature’s processes, viewing materials as nutrients circulating in healthy, safe metabolisms.

Extended Producer Responsibility: A policy approach where producers are responsible for the treatment or disposal of post-consumer products.

Reverse Logistics: The process of moving goods from their typical final destination to capture value or ensure proper disposal.

Innovative Approaches and Models

Biomimicry: An approach to innovation that seeks sustainable solutions by emulating nature’s time-tested patterns and strategies.

Circular Procurement: Purchasing products or services that follow circular economy principles, prioritizing reuse, repair, and recycling.

Sharing Economy: An economic model based on sharing underutilized assets, from spaces to skills to stuff, for monetary or non-monetary benefits.

Remanufacturing: The process of returning a used product to at least its original performance, often with a warranty equivalent to or better than that of the newly manufactured product.

Refurbishment: The process of returning a product to good working condition by replacing or repairing significant components.

Circular Business Models: Strategies that create, deliver, and capture value while maintaining products and materials at their highest value.

Material Passport: A digital set of data describing defined characteristics of materials in products, which gives them value for recovery and reuse.

Urban Mining: The process of reclaiming compounds and elements from products, buildings, and waste.

Circular Supply Chain: A system where resources are continually recirculated instead of being disposed of at the end of their use.

The R-Ladder Framework

  • R0 Refuse: Avoid using or accepting products or materials that are not sustainable.
  • R1 Rethink: Redesign products or business models for sustainability, e.g., improving energy efficiency.
  • R2 Reduce: Minimize the use of resources, emissions, and materials.
  • R3 Reuse: Extend the life of products and spaces by reusing them.
  • R4 Repair: Fix products to extend their functionality.
  • R5 Refurbish: Restore products to good working order.
  • R6 Remanufacture: Rebuild products using a combination of reused, repaired, and new parts.
  • R7 Repurpose: Use discarded products or parts for new purposes.
  • R8 Recycle: Process materials for upcycling or downcycling.
  • R9 Recover: Incinerate materials for energy recovery.

Analytical Tools and Metrics

Material Flow Analysis (MFA): A tool to quantify flows and stocks of materials in a system, helping to optimize resource use.

Circular Marketplaces: Platforms that facilitate buying and selling second-hand or refurbished products, promoting resource efficiency and waste reduction.

Eco-Design: Designing products with consideration for their environmental impacts throughout their lifecycle.

Life Cycle Assessment (LCA): A technique to assess environmental impacts associated with all stages of a product’s life.

Industrial Ecology: The study of material and energy flows through industrial systems to improve sustainability.

Governance and Strategy

Circular Economy Indicators: Metrics used to measure the progress and effectiveness of circular economy initiatives.

Circular Economy Policy: Regulations and guidelines aimed at promoting circular economy practices.

Resource Efficiency: Using Earth’s limited resources sustainably while minimizing environmental impacts.

Sustainable Consumption: Using products and services that meet basic needs while minimizing the use of natural resources and toxic materials.

Sustainable Production: Creating goods and services using processes that are non-polluting, energy-efficient, and safe for workers and consumers.

Circular Economy Business Models: Business models designed to create value by extending product lifecycles and keeping materials in use.

Circular Economy Strategies: Approaches and actions taken to implement circular economy principles, such as designing for longevity and enabling recycling.

Circular Economy Roadmap: A strategic plan outlining steps to transition to a circular economy.

Circular Economy Metrics: Quantitative measures used to evaluate the performance and impact of circular economy initiatives.
