Abstract:
The use of animal by-products (ABPs) is undoubtedly an immense contribution towards a circular bioeconomy where these biological resources and their waste streams might be recovered into value-added products due to their abundance of protein and fat, carbohydrate, minerals, vitamins as well as other nutrients. With the aim of contributing to the circular bioeconomy and reducing the management of solid by-products in tannery facilities, two different bioprocesses have been developed to enable the integrated management of both lime and fresh fleshings, which are classified as Category 3 ABPs. Fleshings have an average content of 15% fat, 20% protein and 65% water. For this reason, the fat fraction is separated from the protein and liquid protein fraction to process them independently by means of two different bioprocesses. Therefore, this research proposes the recovery of ABPs to minimize the impact in the tanning industry, mainly transforming animal fat into biodiesel by an innovative process, as well as discarding protein fraction into protein-based products such as amino acid free based biostimulants, as more sustainable alternative to synthetic ones.
