The effectiveness of the mechanical treatment of municipal waste using the example of a selected installation

Abstract

The mechanical treatment of waste using specialized equipment allows the separation of significant amounts of secondary raw materials. To a large extent, the effectiveness of such a process depends on the quality of the input – one efficiency value is achieved during the segregation of mixed municipal waste, and the other one – during preprocessing of waste from separate collection. The work analysed the data on mechanical processing in a mechanical-biological treatment plant for municipal waste. The mechanical part of the installation is equipped with optical-electronic and electromagnetice separators, as well as manual sorting cabins. Results were obtained to compare the efficiency of the separation of secondary raw materials and energy fractions for further use, as well as the amount of undersieve fraction requiring biological stabilization and ballast waste, which are directed to landfilling.
