HIGHER UTILIZATION OF WASTE FROM THE FOOD INDUSTRY THROUGH BIOTECHNOLOGICAL METHODS.

Until now, the most important way to get rid of food waste was to use it in animal feed. Four methods are used to remove food waste: recovery in agriculture and animal husbandry, incineration, anaerobic fermentation, composting. This paper aims to evaluate new methods of recycling waste from the food industry through biotechnological methods. The wastes that were the subject of the research were the following: apple pomace, bakery waste, milk whey. All these have been processed using the strains of the Biotechnology Faculty Collection in order to determine the potential to obtain useful products of high economical value like bioethanol or probiotics. The experimental yield of 0.26-0.24 l of bioethanol/1000 g of food waste was at the minimum data mentioned in the literature (0.265 l) but justifies the capitalization of this food waste.
