Storages of industrial waste are danger and secondary raw materials sources: pathways to use in the circular economy

Abstract

The work highlights the dangers caused by industrial waste that is stored for a long time in repositories. The largest waste storage site of the chemical industry in the Luhansk region is described in detail. More than 100 types of waste are stored at the landfill. PJSC “Severodonetsky Azot” is considered the owner of the landfill, but nearby are the waste storage facilities of other largest enterprises of the region: “Rubizhansky Krasytel”, Scientific and In-dustrial Association “Zarya”, Lysychansk Plant of Rubber and Technical Products, and Scientific and Industrial Association “Skloplastik”. The impact of landfill waste on the environment is determined not only by the dura-tion of waste storage and the technical imperfection of the repository but also by the geological structure of the location region. The most dangerous impact of storage is on the state of water bodies in the region and on underground sources of drinking water supply. This fact is evidenced by long-term observations of water quality in water supply sources given in the work. Ways of processing certain types of waste contained in the landfill are proposed. The general characteristics of solid industrial waste processing methods are given, a description of the possible utilization of certain types of industrial waste into mar-ketable products is given.
