The Finnish city of Lahti has been pioneering industrial symbiosis at the Kujala Waste Treatment Centre where all sorts of waste are reused. Several companies have established interconnected material flows, thus making one’s residues another one’s raw materials.
CuanTec is a Scottish blue biotech company that replaces plastic with natural alternatives. Sourced from waters of the Atlantic, CuanTec takes waste from fisheries and obtains the natural biopolymer chitin. Their process uses biology rather than chemistry to create chitin and chitosan of high quality and purity, which are in demand for over 3,000 industrial uses around the world.
Wolkat is an family owned group of innovative, international textile recycling companies. It is offering a circular solution for textiles. Collected textile is transformed in-house to new products through sorting, recycling, spinning and weaving. All collected textile is transformed into a final product with hardly any water or any dye, leaving only 4-5 % waste from all textiles.
Sika has developed a high-performance elastomer for the clean repair of the rubber substrate of conveyor belts and industrial rubber elements. This "liquid rubber" enables on-site repair and lengthens the product life of used belts.
The Super Circular Estate project addresses the challenge of changing housing needs. The Parkstad Limburg region’s population, is estimated to shrink by 27% in the next 30 years, calling for a radical reorientation in housing facilities. The project aims at demolishing vacant outdated high-rise apartment buildings, and reuse their components to establish new social housing units.
NAFIGATE’s Hydal Biotechnology uses waste cooking oil to produce a fully biodegradable and biocompatible PHA biopolymer named Hydal (Polyhydroxyalcanoates). This is the first biopolymer of its kind being produced on an industrial scale at an affordable price.
Renewcell's technology dissolves used cotton and other natural fibres into a new, biodegradable raw material: renewcell pulp. It can be turned into textile fibre, be fed into the textile production cycle and meet industry specifications. This is the link that has been missing from the cycle, and will enable the way fashion is produced and consumed to be transformed into a never-ending loop.
