Abstract


The use of resources that have not been directly used for their intended purpose is one of the important tasks of sustainable urban development. The need for an integrated approach to the problem of waste management is realized all over the world. In recent decades, there has been a trend in Ukraine for a significant increase in waste. European experience in handling solid domestic waste uses various processing methods: recycling on the basis of separate collection, sorting, composting and thermal processing with generation of thermal and electric energy. In Ukraine, the most common method of handling waste remains burial in landfills that do not meet European standards, are not properly equipped, they do not comply with the norms and rules of storage. This leads to contamination of groundwater, as well as to the release into the atmosphere of various compounds. No less problem is the accumulation of phosphogypsum in industrial waste dumps. It is necessary to develop innovative technology of a complex for utilization of phosphogypsum using thermal energy of solid domestic waste. The article compares the technological characteristics of aggregates for incineration of solid waste and the production of semi-aqua gypsum to identify the possibility of their interfacing, and also formulated tasks for eliminating inconsistencies in interfaced technologies. The equipment of thermal units of interfaced technologies is offered.
