WORLD EXPERIENCE OF TRANSITION TO CIRCULAR ECONOMY MODELS ON THE BASIS OF USE OF WASTE-FREE TECHNOLOGIES IN AIC

The article is devoted to the issues of world experience of transition to models of circular economy on the basis of use of waste-free technologies in agro – industrial complex. The main differences of the circular model of the economy from the linear (traditional) one are determined. The ecological, economic and social advantages of the circular economy both at the entrance and at the exit from the circular model of economy are singled out. The evolutionary development of R-principles of formation of the concept of circular economy from 3R to 10R is investigated, which proves the dynamism and complexity circular economy. It is substantiated that the circular economy covers issues of energy efficiency, reduction of pollutant emissions, creation of in-novative and efficient methods of production and consumption, optimization of waste management on a cyclical basis. The na-tional peculiarities of the transition to the model of circular economy in some countries of the world are analyzed, in particular, in all cases the concept of circular economy is related to the recycling of waste by environmental impact on the environment. It is proposed to use the concept of “circular bioeconomy” when using waste-free agro-industrial technologies, which should be considered as a combination of the concepts of “circular economy” and “bioeconomy”. By circular bioeconomy we mean a strategy aimed at reducing dependence on fossil fuels, the transition to renewable energy sources and ensuring sustainable economic development through the use of waste-free technologies. It is established that the most promising model of circular bioeconomy based on the use of waste-free agro-industrial technologies is the production of biogas from agricultural waste. The current state of development of biogas technologies in some countries of the world is determined and the advantages for agricultural enterprises from the introduction of environmentally friendly waste-free technologies for biogas production from waste are determined. Based on the research of world experience in implementing a circular economy model using waste-free agro-industrial technologies, a potential scheme for biogas production from agricultural waste to ensure energy security of the industry and characterized the environmental effects of its implementation.
