Description: 

Before a shirt is worn for the first time it has been through more steps than most customers realize. Often one producer makes the yarn, another knits or weaves it into textile fabric, and a third makes the shirt from the fabric. Now it’s ready for the customer to wear.

When garments are worn out or no longer wanted some are sold second-hand or used as hand-me-downs, but the vast majority end up in landfills or are incinerated. Much too few are recycled due to the fact that cotton and viscose can’t be recycled with satisfactory quality on a large enough scale.

Re:newcell's technology dissolves used cotton and other natural fibers into a new, biodegradable raw material, re:newcell pulp. It can be turned into textile fiber, be fed into the textile production cycle and meet industry specifications. This is the link that has been missing from the cycle, as the way fashion is produced and consumed can finally be transformed into a never-ending loop.

Main results: 

Re:newcell's technology transforms high cellulosic waste into pure, natural dissolving pulp, re:newcell pulp. It is an efficient process that reuses chemicals and is up and running in the Kristinehamn, Sweden, demo plant.

The Kristinehamn plant produces 7,000 tons of biodegradable re:newcell pulp per year and runs on renewable energy. This allows Re:newcell to get the experience that will allow the design of full-scale plants, each meant to produce approximately 30,000 tons of re:newcell pulp per year.

If one kilo of clothing is recycled instead of being produced from virgin sources, it saves thousands of liters of water and decreases emissions of both CO2 and chemicals.
