Founded by innovators from Stockholm’s KTH Royal Institute of Technology in 2012, Renewcell is a multi-award-winning sustaintech company based in Sweden.


The company’s vision is to inspire an Industrial Evolution to a sustainable world by producing high quality materials from recycled textiles.
Through its patented process, Renewcell is able to upcycle cellulosic textile waste, such as cotton clothes, transforming it into a pristine new material called Circulose®. Renewcell is regularly recognised for its work to make fashion sustainable. Most recently, Renewcell was named one of the World’s Most Innovative Companies 2021 by Fast Company. Circulose® was also included on TIME Magazine’s list of the 100 Best Inventions 2020.
Circulose® is a branded ‘dissolving pulp’ product that Renewcell makes from 100% recycled cotton textiles.
Dissolving pulp is what the textile industry uses to make viscose, lyocell, and other types of ‘man-made cellulosic fibers’. The only difference with Circulose® is that the pulp is made from textile waste instead of wood.
Recycling clothes finally works.
