Abstract(s)
Agro-food industries produce large amounts of wastes challenging innovative and
efficient valorisation strategies promoting the circular bioeconomy concept. Anaerobic
digestion technology is an interesting route for bioenergy recovery in the agro-food chain
sector. In this work, a simple approach is proposed for assessing energy performance of
livestock manure and mixed sewage sludge, as substrate by coupling the potential
addition of several agro-food biowastes (co-substrate: fruit and vegetable biowastes, fish
canning industry, other manures, coffee wastes, and non-edible crops). The results
obtained showed an increase of energy performance indicator ranging from 30 to 250%
and 62 to 539%, for livestock manure and mixed sewage sludge, respectively. This
conceptual approach for feedstocks promotes the circular bioeconomy as it encourages
the stakeholders to a smart use of anaerobic biotechnology at rural-level or urban-level
