Project objective: Develop a technology for the production of a wide range of technical products using recycled polyethylene through the processing of rotational composites, ensuring the efficient use and recycling of plastic waste.
Expected results: Optimal formulations will be developed based on various compositions of secondary rotary polyethylene with improved performance and high mechanical properties of products. New designs of technical products, such as underground tanks and septic tanks, have been developed with a guaranteed high service life (taking into account the reduced mechanical properties of compositions based on recycled polyethylene). The possibility of developing a method for rapid diagnostics of internal stresses in rotoformed products by means of ultrasonic flaw detection has been studied. An industrial approbation of the proposed technology for processing rotary composites based on recycled material has been performed. The necessary regulatory and technical documentation has been developed, including the technological process and standards of the organization for at least one type of technical products.
Project Description: Today, the problem of environmental pollution from plastic waste, particularly polyethylene, remains acute. The most effective solution is its recycling. One method for recycling polyethylene is rotational molding (RM), which can be used to produce various technical products, such as underground storage tanks. However, there is currently no comprehensive technology for recycling secondary rotational polyethylene (RPE), which creates a number of challenges that need to be addressed. Firstly, it is necessary to develop optimal formulations for composites containing recycled polyethylene, which will ensure high performance characteristics of the products. Secondly, given the reduction in mechanical properties (due to high temperatures and oxidation processes) during the processing of composites based on recycled polyethylene, the material's strength characteristics deteriorate, making standard product designs incapable of guaranteeing their service life.
Therefore, it is necessary to design new structures using modern calculation methods, such as the finite element method, which will take into account the loads that occur in products, such as underground tanks, for example, at ground pressure. Due to the wide range of parameters of recycled plastic, industrial practices often encounter the problem of highly stressed products being processed with recycled polyethylene, which can lead to their failure during use. Therefore, thirdly, an equally important task is to develop a rapid method for detecting internal stress in products using ultrasonic flaw detection. Solving this problem will allow for timely adjustments to composite formulations, minimizing internal stress and extending the service life of the products. Thus, the development and implementation of new technologies for recycling secondary polyethylene, quality control using ultrasonic flaw detection, and the optimization of product designs (based on the finite element method) are promising areas that will significantly improve the environmental situation and increase the efficiency of plastic waste utilization.
