The role of eco-industrial parks in promoting circular economy technologies in the regions

The authors proposed a method for evaluating the relationship between eco-industrial parks with circular economy technologies. The novelty of the study was the introduction of a new term, the specialization index of circular economy technologies for eco-industrial parks. The authors proposed an algorithm for calculating this index. It is based on four types of technologies: waste treatment, industrial symbiosis, water resource efficiency, and renewable energy. The authors conducted a correlation analysis of 15 regions for 2021. Eco-industrial parks appeared due to the development of circular economy technologies. The balance of demand and supply formed only for waste treatment technologies as of 2021. The industrial symbiosis technology is at an average level in industrial parks. In 2021, markets for water efficiency and renewable energy technologies began to emerge. Ecoindustrial parks must implement the full range of circular economy technologies. This will make it possible to achieve the goals of sustainable development.
