This paper aims to identify the correlation between the mineral contents in agropellets and particle matter and bottom ash characteristics during combustion in domestic boilers. Four agrifood residues with higher mineral contents, namely grape marc (GM), tomato waste (TW), exhausted olive mill solid waste (EOMSW) and olive mill wastewater (OMWW), were selected. Then, seven different pellets were produced...
In Tunisia, seasonal and centralized discharges of tomato waste and grape marc generated from agri-food industries have negative effects on the environment. Characterization of these residues shows that their calorific values are suitable for their energy recovery. However, the high mineral contents and the low bulk densities limit their direct use as biofuel. Therefore, a blending process using sawdust...
Mediterranean countries generate large amounts of olive oil byproducts mainly OMWW (olive mill wastewater) and EOSW (exhausted olive solid waste). Although solid residues have various valorization strategies, there is no economically viable solution for the OMWW disposal. This study aims to recover the OMWW organic contents through solid biofuels production. Hence sawdust and EOSW were used for the...
