Modern biopositive technologies of waste processing in the utilities and construction industries
Introduction. In this article the analysis of certain biopositive technologies applied to processing or recycling of construction waste, municipal sewage, and paste-like slurries of organo-mineral nature is performed. The relevance of this research is confirmed by the steadily growing number of publications and currently implemented government programmes aimed at solving such problems. The paper summarizes the results of research into the treatment of wastes having different origin. Materials and methods. The analysis of the research literature and patents for inventions, as well as publicly available technologies used in waste processing and recycling is performed. Selection of biopositive technologies based on the chemical nature of materials and their groups is described. Biopositive technologies, most effectively applied to construction materials, are identified for the purpose of converting engineering structures into secondary raw components. The co-authors demonstrate the application of a biopositive technology to sludge decontaminated at municipal waste water treatment plants and to hot waste generated by the hydrolysis industry, as well as technologies used to process special thermal insulation and waterproofing materials. Results. The use of water-organic emulsions as active components in effective regeneration of asphalt granulated concrete mixtures is considered. Сompositions, concentrations and sedimentation stability of such emulsions have been identified. The results of the study of physical, mechanical and hydro-physical properties of the asphalt-concrete granulate treated with water-organic emulsions are described. This regeneration technology helps bitumen to restore binding properties on the surface of the asphalt-concrete granulate and makes this composite applicable as a material designated for the bottom layers of the road pavement. Conclusions. These biopositive technologies make it possible to efficiently and rationally process or recycle a wide range of municipal and construction waste into structures and products having various applications. Recycling, composting and plasma technologies are considered in this case.
