Valorisation des déchets en industrie agroalimentaire

Abstract

The agro-Food industry is the main one which rejects in the country a large quantity of waste which has harmful effects on the environment, and at the same time on the consumers, the producers and the industrialists but this waste can be recovered and used in different areas, Waste recovery, when possible it allows to extract useful products. With methods considered as industrial processes. our research focuses on the recovery of waste in quleques agrifood industry such as (whey, poultry, olive trees, dates, sugar) for several years The research carried out has made it possible to understand the nutritional value of whey, as well as the possibilities of its use in food from the livestock, at the same time The valorisation of olive oil residues has become a double necessity; ecological and economical. Indeed, it would make it possible to reduce increasingly significant pollution, and to contribute to the improvement of profitability and as well as for the poultry sector.This waste constitutes a potential source of recoverable biomass because of its organic matter content and in fiber; on the other hand the date processing industries produce various products such as date paste, syrup, honey, jam, vinegar, etc. There are many uses of date palm products and by-products with making ancestral (traditional) and biotechnological applications Likewise sugar. In addition to this commodity, the processing of these plants allows the production of by-products such as molasses and pulps for beets, molasses and bagasse for sugar cane.
