|2 billion m2 of leather is annually produced worldwide. Leather industry causes serious pollution and health risks by producing 5 billion kg of toxic chemical waste and 340 billion litres of wastewater every year. We have developed a technology to produce gelatin-based leather-like textile using only natural, non-toxic substances. Gleather is made by combining nanotechnology with tanning chemistry to produce material chemically identical to leather. Compared to leather production, fabricating Gleather requires 3 times less raw material. Additionally, it is possible to adjust the characteristics of Gleather, including its texture and strength, to customer´s needs. The fabric comes on rolls, simplifying design and cutting process, which in return increases profitability of fashion brands. Producing Gleather on industrial scale could have significant positive impact on the environment.
