TL;DR: In this article, an economic feasibility study of a full scale anaerobic co-digestion plant to treat an olive oil mill pomace (TPOP) and pig slurry (PS) at different ratios were studied in a semi-continuous stirred tank reactor at mesophilic temperature (37°C).

TL;DR: Results showed that the inclusion of brewers’ spent yeast and spent grain in Aquafeeds for gilt-head sea bream show a good protein digestibility and can be considered as suitable ingredients to successfully replace fish meal in aquafeed diets.

TL;DR: Two trials were conducted to test the effect of partial replacement of fishmeal by two brewery industry by-products, yeast and spent grain, included in isoproteic and isolipidic diets for gilthead sea bream, finding them to be a potential source of protein to reduce the use of plant proteins or fish/animal by- products (trimmings) and increase the sustainability of both sectors.

TL;DR: In this article, a MCDA tool has been developed to help decision-makers (private or public waste management bodies and companies) to implement food waste valorisation strategies, which reduces the time required to evaluate the different scenarios for each study case, as well as facilitating a sensitivity study when geographic, technical, economic and environmental criteria values are modified.

TL;DR: Inclusion of 20–30% of brewers' spent yeast and spent grain in the feed for carnivorous fish either from fresh (rainbow trout) or marine (gilthead seabream) gave similar results to a feed with fish meal as the main protein source and show a good protein, lipid and amino acid digestibility.
