Justification of Methods of Polymeric Waste Processing in Agricultural Production

Abstract

The development of industry has led to the unlimited technological application of polymers, ranging from plastic bags, rubber, fabrics, paper and other materials. Displacing traditional materials, polymer products began to be used in agriculture. Polymers are used to make films for soil cover (mulching), anti-hail nets, shaft bushings, gears, body parts, tanks for storage and transportation of fertilizers and working fluids and many other parts. The operational properties of polymer products are becoming more and more perfect, but at the same time the methods of polymer waste management and their utilization are being developed and complicated. Over time, they can no longer be used for their intended purpose, so they are discarded and sent to landfills, while polymers are valuable structural materials and their reuse will not only be positive for the environment, but can also become a profitable branch of the agro-industrial complex. Pellet production is one of the methods of recycling polymer waste, which in the future can be used for the production of new parts, as well as added to the composition of composite materials based on organic or mineral fillers. This article examines the problem of recycling polymer waste by improving their processing technologies. The analysis of existing methods of utilization and processing of polymeric waste generated in agriculture is carried out. Determination of physical and mechanical properties of polymer waste, in particular thermoplastics. Taking into account the received information, conclusions are made and the analysis of methods of utilization and processing of polymeric waste in secondary raw materials is carried out.
