Circular Design and Manufacturing

Detailed overview of innovation with sample startups and prominent university research


What it is

Circular design and manufacturing represent a fundamental shift in how we create and use products, moving away from the traditional linear model of “take-make-waste” toward a closed-loop system. It involves designing products with the entire lifecycle in mind, ensuring that materials are kept in use for as long as possible, minimizing waste generation and resource depletion. This approach embraces sustainable material selection, product longevity, ease of disassembly, repair, and remanufacturing, ultimately promoting a regenerative and circular economy.

Impact on climate action

Circular Design and Manufacturing significantly bolsters climate action by reducing resource consumption and waste generation throughout product lifecycles. Through efficient material use and closed-loop systems, it minimizes emissions and energy demand associated with production, fostering a sustainable economy while mitigating environmental degradation.

Underlying
Technology

  • Cradle-to-Cradle Design: This design philosophy emphasizes creating products that are “nutrients” for the technical or biological cycles, ensuring that materials can be perpetually cycled without loss of quality or value.
  • Design for Disassembly: Products are designed with modularity, standardized components, and easily accessible fasteners, enabling straightforward disassembly for repair, upgrade, or material recovery.
  • Material Selection for Circularity: Prioritizing renewable, recyclable, or biodegradable materials, minimizing the use of hazardous substances, and designing for material compatibility to facilitate end-of-life sorting and recycling.
  • Remanufacturing and Refurbishment: Incorporating design features that allow for easy remanufacturing or refurbishment of products, extending their lifespan and reducing the need for new production.
  • Industrial Symbiosis: Creating networks of businesses where the waste or byproducts of one industry become inputs for another, minimizing waste and maximizing resource utilization.

Prominent Innovation themes

  • Biomimicry for Sustainable Design: Drawing inspiration from nature to design products that are efficient, durable, and can be safely returned to the environment.
  • Digital Product Passports: Utilizing digital product passports to track materials and components throughout the lifecycle, enabling efficient disassembly, repair, and recycling.
  • Additive Manufacturing for Circularity: Leveraging 3D printing to create customized and on-demand spare parts for product repairs, extending lifespan and minimizing waste.
  • Closed-Loop Supply Chains: Developing closed-loop supply chains where materials are recovered and reused within the production process, minimizing waste and reducing reliance on virgin resources.
  • Design for Product-as-a-Service: Designing products specifically for Product-as-a-Service (PaaS) models, prioritizing durability, repairability, and ease of maintenance.
