The study focused on two key process parameters: the effect of acid hydrolysis of the substrate and the initial concentration of fermentable sugars, with the goal of optimizing ethanol yield. In parallel, the solid residues resulting from the fermentation were recovered and treated through aerobic composting, as part of an integrated valorization approach. The resulting compost was characterized by physico-chemical analyses (pH, moisture, C/N ratio) to assess its stability and maturity. Experimental results showed that acid hydrolysis significantly improves sugar conversion into ethanol, and that the initial sugar concentration strongly influences fermentation efficiency. This approach demonstrates the feasibility of a coupled bioethanol/compost process on a small scale, aligned with sustainable development and rational management of agricultural waste. 2025-06-01T00:00:00Z http://dspace.univ-constantine3.dz:8080/xmlui/handle/123456789/1246 Perception de l’hépatite Virale B et de sa prévention par le personnel de santé buccodentaire à Constantine en 2020 Kaba, Meriem; Souki, Ines; Boulahia, Ratiba; Belhoula, Karima; Djaberlkhir, Hidaya; Mellah, Aya; Charaoui, Yousra; Belhadj, moustfa Naoufe; Bahr, Sarra; Boustila, Soufia; Bensid, Kenza; Bouhalata, Leila; Souko, Aya; Cheib, Sarra; Zeggari, Djahida; Encadré par : Pr.
