From leather wastes to leather: enhancement of low quality leather using collagen recovered from leather tanned wastes

Clean Technologies and Environmental Policy, 2023
AbstractLeather industry produces huge amounts of solid wastes. In the last decade, several methods for the recovery and valorization of these wastes were developed, mainly focused on the extraction of collagen using chemical methods. The extracted collagen, due to its poor quality, is mostly used in agriculture as a nitrogen source ingredient of ...
