Circular bioeconomy of pea processing residues

Waste generated annually in agricultural production has a negative impact on the environment and public health. The circular economy concept aims to minimize waste generation in this economic sector. The objective of this study is to assess the level of agricultural waste recycling, identify recycling options and the benefits of reusing pea grain processing waste, and propose a pea grain processing waste management model in the context of the circular economy concept. The material for this scientific article included regulatory documents, scientific publications on the research topic indexed in the Scopus and Web of Science databases, as well as the author’s developments in the field of waste recycling. In preparing the article, methods of searching, selecting, systematizing and interpreting information, as well as methods of analysis, synthesis, and design were used. It has been established that a linear economic model functions in modern agricultural production. A tendency is observed towards an increasing share of grain processing waste subject to recycling and neutralization. Applying circular economy principles to grain processing waste allows for the production of value-added products. Directions for establishing a closed- loop economy for the reuse of pea grain processing waste are proposed. Their environmental, economic, and social benefits are demonstrated. A model for recycling pea shells to produce biodegradable packaging is presented. The most promising areas of waste recycling include biotechnology, biofuel and bioenergy production, bioconversion, and nanotechnology. In the near future, an approach to waste management that integrates various subsystems of agricultural production will be particularly relevant.
