Circular design plays a central role on the way to a viable circular economy. In order to provide actors in the product development process with a simple set of rules for the design of circular products, the Institute of Design Research Vienna has developed the Circular Design Rules.
In cooperation with designaustria and with the kind support of the Federal Ministry for Climate Protection and the Vienna Business Agency, a toolkit was developed that contains nine rules for circular design and a scorecard. With the goal of closing product and material cycles, the tool provides orientation and shows progress along the way.
Human activities and products are exceeding the biomass of our planet, while natural resources become scarce and additional emissions cause an imbalance in natural systems.
The proper use of materials is a prerequisite for Circular Design. This means, on the one hand, keeping renewable and sustainable resources, from planting to biodegradation, in the loop (Biological Cycle); on the other, the use of limited and non-renewable technical materials, which in the future will be recovered from products and kept in use (Technical Cycle), instead of the continued extraction of limited resources from our planet. The accumulated inventory of human activities then serves as the source materials for the production of new products.
Hence, a main goal of Circular Design is to develop products in such a way that biological materials find their way back to nature, while the value of technical mate- rials is preserved to the greatest degree possible.
With plastics, for example, we see that a few less polymers make it possible to create a local circular economy, which employs decentralized manufacturing techniques to manufacture new products from old materials.
Design the product out of renewable materials or recyclate.
Design the product out of reusable or degradable materials.
Design the product with little material.
Modularity and the separability of products into their components prove to be key principles in Circular Design. The possibility to replace or extend parts of a product ensures the long-term use of products as it involves the repair and maintenance, but also extension and improvement of products.
This is also the first step in the production of new products from existing components (Re-Manufacturing). The procurement of raw materials and production costs are thereby reduced. Hence, design innovations are required on the level of components, which ensure that the products remain attractive for a long time, can be adapted to technical developments, and be reintegrated into production processes. In the spirit of Circular Design, a task is to imagine multiple combinations of the components on hand and also future ones, and thereby develop new and open product systems.
Standardized components along with new technologies for local production facilitate adaptation to new requirements or may even empower users into becoming co-designers.
Design the separability of the product.
Design the product modularly.
Design updates and upgrades for the product.
Products must be consciously embedded in systems to be circular. The design of product service systems accesses new consumption patterns and markets, which are based on services without compromises but also the conservation of resources. For designers, this entails the development of design concepts above and beyond product design, which accompany the product in its complete life cycle.
A multitude of users can benefit from new product service systems, while corresponding business models promise manufacturers a reliable income and customer loyalty. Moreover, when the product remains the property of the service provider, the path to the reuse of components and materials is short, and it is thus the manufacturer’s responsibility to close the loop.
Once the system – in which high-grade products, components, or materials stay in a loop – has been put in place by the manufacturer or in cooperation with partners, then even a shorter service life can fulfill the objectives of a circular economy.
Design the take-back process of the product.
Design the reuse of products and components.
Design the product as a service.
Circular Design Rules – Version 1.0 for Product Design is available at the presentations and via designaustria or the IDRV.
In Kooperation mit
CDR is a research project in the framework of the New European Bauhaus Initiative. The rules have been selected from a comprehensive collection of design patterns, which could effectively introduce a positive system change.
