A circular system innovation for shoe production – step 1

In Sweden, about 40 million pairs of shoes are imported annually, which gives a climate impact of 1.2 million tonnes of CO2-eq, corresponding to about 30 kg of CO2-eq per pair. An average shoe also contains up to 30 components, which makes recycling a great challenge with today’s available technologies. The project’s vision is to introduce an innovative circular system innovation for shoe production on the market, using textile residual streams as a resource base. It is primarily the progress, of recent years, in two areas that the project intends to build the concept on; (1) groundbreaking research in (nano) cellulose at Stockholm University (2) state-of-the-art 3D printing technology. Combining these enables a new material and product flow that can be circulated in a closed system.
