Abstract

Algerian market waste from grapes represents an interesting source for the recovery of market waste into renewable energy, while eliminating this waste to contribute to the protection of the environment within the framework of sustainable development. Thiswork studies the production of bioethanol from three varieties of grapes existing in the Algerian market. This waste has undergone physico-chemical and microbiological analyzes before being fermented by the yeast Saccharomyces cerevisiaeat the laboratory level. The results obtained by these analyzes confirmed to us that the grapes contain a significant quantity of sugar and also confirmed the presence of some microorganisms such as mephilic total germs.Finally, the ethanol was recoveredby distillation, making it possible to reach 91% alcohol. The results show that alcohol from grape waste has great potential for the production of ethanol by referring to that from waste from the potato processing industry.
