The article examines the key points of creating eco-industrial parks in the Lviv region and reforming existing industrial parks according to the principles of circular and green economy. The intensive increase in the number of industrial enterprises in the Lviv region is due to the active relocation of enterprises from the war zone of Ukraine. The purpose of the article is to justify the feasibility of creating eco-industrial parks in the Lviv region according to the principles of circular and green economy. The authors recommend the principles of selecting industrial enterprises in the territories of industrial parks, taking into account industrial symbiosis. As part of research cooperation, we conducted and researched the stages of the design, construction, and development of industrial parks in the Lviv region of Ukraine. Practical recommendations have been developed and proposed for the creation and implementation of the production of environmentally-friendly products with further processing and the secondary cycle of waste use in order to reduce the use of natural resources and environmental pollution, and increase the socioeconomic development of the western region of Ukraine.
It has been substantiated that the increase in the concentration of heavy metals in the environment has especially aggravated in the conditions of military operations on the territory of Ukraine. The use of woody plants for the purposes of phytoremediation is one of the most effective options for optimising the state of the environment in urban ecosystems, regardless of the nature and source of contamination by metallic elements, which is of significant relevance in the conditions of post-war environmental restoration of Ukraine. The purpose of the study is to explore the peculiarities of some heavy metals accumulation by the assimilation apparatuses of the black locust (Robinia pseudoacacia L.) plants growing in the recreational areas of the city of Dnipro in order to further optimise tree plantings with the aim of improving the environment. The content of heavy metal elements (Cu, Zn, Pb, and Cd) in the biomass of the Robinia pseudoacacia L. leaves and in the soils of Dnipro recreation areas has been determined. The intensity of the accumulation of heavy metals in the phytomass of the Robinia pseudoacacia L. represents the following sequence Zn > Cu > Pb > Cd, which demonstrates a more intense absorption and accumulation in the phytomass of the leafy fraction of Zn and Cu in the phytomass of the deciduous fraction, and less significant of Pb and Cd. With the help of geo-information systems, cartographic material has been developed. It demonstrates the concentration gradient of Pb, Cu, Cd, and Zn in the assimilation organs of the black locust plants in the city of Dnipro recreational areas. Based on the cartographic analysis, it has been proved that the general condition of the soils in the recreation areas of Dnipro is characterised by significant disproportions in the level of pollution. The maps show the existing potential of the accumulative capacity of Robinia pseudoacacia L. to deposit Pb, Cu, Cd, and Zn, which allows for additional city functional zoning by considering phytoremediation functions of the existing and planned green spaces.
