Biorefineries offer an advantageous and sustainable solution for managing by-products from the agro-industry while enabling the recovery of valuable molecules and biogas production from residual biomass. This study applied this approach to the beer industry's main by-products: Brewery-s Spent Grain (BSG). BSG is typically used as animal feed but shows potential for biorefinery applications due to its high protein content and favorable C/N ratio. By treating this biomass with an ionic liquid consisting of triethyla...

The olive oil sector is one of the most widespread agricultural and agro-industrial activities in the Mediterranean region, and it also produces a significant amount of waste biomass. This research aimed to find energy valorisation for the olive oil by-products through biogas/biomethane production from olive pomace (OP) and olive mill wastewater (OW). To this end, these biomasses underwent preliminary treatments: the OP was processed using an ionic liquid (IL) consisting of triethylamine and sulfuric acid [Et3N][H...

The most attractive option to recover methane trapped within natural gas hydrate reservoirs, consists of the so-called -replacement process-, mainly based on the contemporary injection of carbon dioxide during the mining process. If appropriately carried out, this process allows to improve the amount of methane recovered, preserve the crystalline hydrate cages and permanently store enough carbon dioxide to make this source definitively carbon neutral. For that reason, this process is widely studied worldwide. Howe...
