To avoid disposal of mushroom and lignocellulosic by-products and allow the productionof biodegradable bio-based products that will help to replace the existing ones based on fossil resources
The BIOrescue project focused on developing and demonstrating a new innovative biorefinery concept based on the cascading use of spent mushroom substrate (SMS) supplemented by wheat straw and other seasonal underutilised lignocellulosic feedstocks. i.e., pruning residues, residual citrus peels and wastes
BIOrescue focused on extracting two main components of these feedstocks: lignin and sugars. To maximise extraction yields, the project developed two innovative biomass pretreatment processes. An organosolv pretreatment was used to obtain the maximum amount of lignin, while sugars are retrieved through thermochemical pretreatment. The sugars are then fermented to produce sustainable and low cost biopesticides. On the side of the lignin, the fractions obtained from the organosolv and thermochemical pretreatment are mixed and submitted to a chemical conversion process to transform lignin into polymers. The products obtained include enzyme cocktail, biopesticide and biodegradable nanocapsules.
Sufficient scale of spent mushroom substrate are required. The global biopesticides market is projected to grow from $6.51 billion in 2022 to $18.15 billion by 2029, at a CAGR of 15.77% in the forecast period, 2022-2029
Development of low cost and sustainable biopesticides from waste, which are less toxic but equally efficient as their fossil-based alternatives on the market.
Use underutilized seasonal feedstock: in addition to using SMS and wheat straw, thereby enabling a second source of income for agriculture farmers
