Circular fiber

Renewcell has actually established a method of upcycling damaged denims and production scraps to make a trademarked product called “circulose” which can be utilized to make brand-new garments.

The procedure to make circulose starts with getting rid of buttons and zippers from the clothes and shredding the fabric waste. The fluff then goes through a so-called “damp phase” of chemical processing, which is “where the magic occurs,” states Harald Cavalli-Björkman, Renewcell’s primary development officer.

“We change the homes of the cellulose particles in the cotton fabrics, such as the viscosity, reactivity and brightness. After that, the product is gone through a fiber separation phase where polyester and other artificial products are secured.”

What emerges from this procedure is a circulose pulp, which is then dried and delivered to clients in square blocks. These manufacturers make restored cellulose fibers, which are then made into viscose and lyocell for the production of brand-new fabrics.

For instance, Renewcell utilizes chemicals which, while safe and in line with ecological policies, are used nonrenewable fuel sources. The business is likewise familiar with the carbon expenses of the transportation they utilize for shipments, both to customers and to its plants.

“It’s a continuous issue for us to be as resource effective as possible. We’re mindful that we can’t indicate the reality that we’re making a circular item, without being sincere about the social and financial effect we’re having, and the methods we might do much better,” states Cavalli-Björkman.

Scraps to specifications

Kleiderly, a Berlin-based circular economy start-up, is likewise recycling old fabrics to make trendy sunglasses. The business gathers clothes consisting of materials such as polyester, cotton, viscose and elastane, eliminates the parts that can’t be recycled and after that utilizes chemicals to break the product down.

“We chose to concentrate on glasses to make the principle of what we’re doing simple to comprehend, and reveal that it truly is possible to upcycle old fabrics and produce worth from them,” states Bassi.

Kleiderly is still at an early phase of advancement, with pilot tasks continuous with a variety of business. Yet its procedure is a microcosm of the effect that might be made on an international scale if more business utilized waste as a resource and embraced circular economy concepts.

“If the EU alone was to utilize circular economy concepts, we might cut in half emissions by 2030,” states Bassi.
