The medical workwear and protective clothing used in hospitals today are mostly disposable products that are discarded after a single use. Much of this apparel is made from petroleum-based plastics such as polyester and polypropylene. This is problematic in two ways. First, it creates enormous amounts of waste in hospitals day after day. Secondly, both the wearing comfort and the functionality of these garments, in which many people have to work for long periods of time, leave a lot to be desired. This is where the Cima project comes in, which has set itself the goal of developing a functional, comfortable to wear and at the same time ecological medical protective clothing. In cooperation with industrial partners, the project succeeded in creating a fully compostable garment made from renewable starting materials that meets the requirements of the circular economy. The products, designed of cellulose fibre, are characterized by a significantly improved wearing comfort as well as a functional and aesthetically high-quality design.
