Food industry byproducts - As potential animal feeds

Agriculture and food industry waste constitutes a major proportion (32%) of world-wide agricultural production. Recovering of nutrients from currently wasted resources and their utilization as feed resource with application of proper processing technologies will help curb the danger of gap between increasing livestock population and available feed resources to meet increasing population demands. Demand for processed foods increased tremendously due to altered lifestyle choice of global consumers with subsequent release of waste production from these processing plants. This waste management in efficient way is essential for enlarging the livestock feed resource base and to reduce food-feed competition. Sugar, starch, beverage industry waste products (beet pulp, molasses, bagasse, DDGS, WDGS, condensed steep liquor etc.) are being used as livestock, poultry and fish feeds. Animal nutritionists made attempts for successful utilization of dried or ensiled vegetable processing and fruit juice industry waste as animal feeds. Although there is successful production of biofuels, bioelectricity from food industry waste, as per United States Environmental Protection Agency (US EPA, 2020) food recovery hierarchy/waste management from food processing industry should be prioritised as follow
