According to foreign media reports, a new article from an international team of materials scientists points out that a leather like material made from mushroom derived biomass may be cheaper than animal leather or its plastic derivatives, while being more environmentally sustainable. For thousands of years, humans have been using animals to make leather. Recently, the environmental cost of large-scale livestock production has become a serious concern. < / P > < p > alternative leather from non animal sources has been welcomed by sustainability advocates. Although these “plain textiles” avoid many of the problems encountered in the production of traditional leather, these synthetic materials also have a big problem of their own. In addition to relying on toxic chemicals, synthetic leather also faces the non degradable problem faced by most plastic products. < / P > < p > “we tend to think that synthetic leather, sometimes called ‘plain leather’, is better for the environment,” said Alexander Bismarck, from the University of Vienna, who is also co-author of the new review. “However, traditional leather may have ethical issues, and leather and plastic alternatives have environmental sustainability issues.” The idea of using fungal biomass as the basis for the production of materials and textiles is not new. As early as the 1950s, papermakers discovered a polymer called chitin in the cell walls of fungi, which can be used to make writing paper. Recently, these fungal derived compounds have been used to make everything from building materials to fashion textiles. The fungus derived leather is a relatively new technological innovation. Fans of mycology know that the little mushrooms that we see coming out of the ground are just a fraction of any known fungus. Underground, it is usually a creeping network of branches called hyphae. Leather is made from this mycelium structure. In this paper, Bismarck and his colleagues argue that advances in manufacturing technology have enabled fungus derived leather to meet consumer expectations for functionality and aesthetics. They believe that fungal leather overcomes the ethical problems of animal leather and the environmental problems of synthetic leather. However, how to raise the production of fungal leather to the industrial level may be one of the remaining obstacles faced by this emerging industry. But that may not be a problem for a long time. Just last year, a team from Finland announced what they called a new industrial process that could expand the production of fungal leather. Bismarck and his colleagues believe that fungal derived leather substitutes will play an important role in the future fabric market. He said the alternatives were sustainable, cheap, ethical, biodegradable and environmentally friendly. < / P > < p > in addition, he added that the great progress of fungus leather and the increasing number of companies starting to produce fungus leather showed that the new material would play an important role in the fabric of the future – both ethical and environmental.
