Abstract
Introduction. National economies are looking for tools to activate the explicit and hidden resource potential. Innovative resource-saving projects are such a tool. Feed production strives to increase its resource efficiency. Study objects and methods. The present research featured the feed industry of the Russian Federation and regional feed mills. It involved structural, functional, and systematic approaches and standard research methods. Results and discussion. Liquid waste proved to be an important resource potential of modern feed production. It contains substances with high nutritional, biological, and energy value and can be used to produce methionine. The experimental part featured an industrial enterprise in the Voronezh region, which expects to produce 1452 tons of methionine worth 58 080 thousand rubles. The profitability will be 616.76%, the gross return on sales − 86.1%, the payback time – 1.44 months, the efficiency of capital investments – 8.45. Conclusion. The innovative project will reduce the negative impact on the environment, increase the resource efficiency of the enterprise, and provide additional income.
