Along with the primary raw materials, secondary raw materials are of great importance in the canning industry. Secondary raw materials are residues and by-products formed during the processing of the primary product, the effective processing and use of which allows to increase production efficiency. This article analyzes methods for the effective use of secondary raw materials, their role in improving the quality of canned products and reducing waste. The environmental benefits and economic aspects of secondary raw materials are also considered. For example, in the production of canned fruits and vegetables, peels, skins and chopped residues can be used as animal feed, natural feed additives or biogas. Thus, the processing of secondary raw materials not only reduces production costs, but also serves to protect the environment. This approach also allows for the development of a sustainable and economically efficient canning industry.
