Abstract
At most of the installations for the mechanical and biological treatment of waste operated in Poland, the 0–80 mm fraction, separated from the municipal waste stream, are completely stored after biostabilization. Such an action does not fit into the EU strategy focused on circular waste management. The purpose of this study was to assess the technical feasibility of recovering the mineral fractions contained in the compost-like-output (CLO) on a technological line designed for glass recovery. The research started in January 2019, lasted for the next 12 months, and covered 29 measurement series. The following two high-energy fractions were separated from the CLO: 10–35 mm light fraction after separation in the air separator (M-1) and 35–80 mm light fraction after separation in the air separator (M-2). The stabilization processing on the glass recovery line allowed for the recovery of two high energy fractions in the total amount of 24.5% of the processed, and it stabilized the product’s mass. In terms of materials, the M-1 and M-2 wastes were a mixture of organic, paper, and plastic materials. Under the Refuse Derived Fuel (RDF) classification, according to the European Committee for Standardization, the tested waste fell within the following classes: waste M-1: 4NCV2Cl4Hg and M-2: 4NCV1Cl4Hg.

Summary
EU law on municipal waste and packaging waste explicitly requires its selective collection as the primary route to waste recycling, which aims to create a circular economic model for Europe The implementation of this model limits the importance of mechanical-biological waste treatment (MBT) technologies on the waste market, resulting in a decrease in the amount of mixed waste (municipal solid waste (MSW)) fed to MBT installations. MBT installations are a bridge between the current state of the solid municipal waste management (MSW) in Europe and the need to meet current needs, and the necessary intensive development of recycling This is confirmed by the operation of approximately 570 MBT installations with a processing capacity of over 55 million tonnes in Europe at the beginning of 2017. It was planned to commission another 120 facilities with a capacity of nearly 10 million tons per year by 2025 [7]
