The search for new effective methods of processing of secondary raw materials in the food industry is a very urgent problem. The biological waste of the food and processing industry is considered to include veterinary confiscates, nonfood waste and little value food products, waste products of food, technical and special products, the corpses of livestock and poultry. This waste has been and remains a valuable secondary raw material. The reasons are our Russian mentality, which allows us to neglect the environment, certain economic reasons and the inefficiency of the supervisory bodies. In Soviet times, large processing plants had workshops for production of feed, fish, feather, horn and hoof and other flour. Waste of smaller enterprises was brought to special plants, where they were either burned or used for production of the same flour. Most of these plants had not been working for a long time, and the rest ones did not cope with the supplied volume of waste. The other side of the problem is that both these plants and the vast majority of enterprises that have their own production of feed and other animal flour use obsolete old technologies and old equipment. The result is a product with low consumer qualities. The variety of nonfood waste of the food industry and the diversity of their application imply the use of different technologies of utilization. And the more advanced these technologies, the higher the profitability of processing and the quality of the products.
