The aim of this study was to determine the role of an installation based on biodrying of municipal waste in a Circular Economy by taking into account the quantitative and qualitative changes in its selectively collected waste stream. As a case study, the Mechanical-Biological municipal waste treatment installation in Olsztyn, Poland, was selected, which is equipped with a separate section for valorizing the selectively collected waste stream. The scope of the work included a complete mass balance of the waste treatment plant, an assessment of the technological efficiency of the municipal waste biodrying installation, and determination of the changes in the main waste from 2016 to 2020. This paper proposes an empirical method for estimating process loss during biodrying and provides many technological results. The average process loss was 23.47%, and on average, 88.9% of the waste produced by biodrying consisted of the Refuse-Derived Fuel fraction. The recovery of commercial assortments from selectively collected waste increased from 84.82% in 2016 to 89.26% in 2020. Considering the current morphology of municipal waste in this region, the maximum share of waste subjected to material and organic recycling processes in the analyzed region could be increased to around 60%, which indicates that Circular Economy targets can be achieved. This work should provide a compendium of information for countries implementing a Circular Economy.

This article presents an innovative solution for drying waste in bioreactors on the example of the Municipal Waste Treatment Plant (ZUOK) in Olsztyn. Shredded mixed waste undergoes fermentation in bioreactors and produces heat for waste drying. Waste transported to the plant is divided into sorted waste which is recycled and mixed waste which is processed into different size fractions. Processed waste is used in the production of alternative fuel which can be burned in dedicated systems in cement plants or incineration plants. Around 5-15% of waste cannot be processed and is landfilled.

Sorting System

The recently finalized research project “ZRR for municipal waste” aimed at testing and evaluating the automation of municipal waste sorting plants by supplementing or replacing manual sorting, with sorting by a robot with artificial intelligence (ZRR). The objectives were to increase the current recycling rates and the purity of the recovered materials; to collect additional materials from the current rejected flows; and to improve the working conditions of the workers, who could then concentrate on, among other things, the maintenance of the robots. Based on the empirical results of the project, this paper presents the main results of the training and operation of the robotic sorting system based on artificial intelligence, which, to our knowledge, is the first attempt at an application for the separation of bulky municipal solid waste (MSW) and an installation in a full-scale waste treatment plant. The key questions for the research project included (a) the design of test protocols to assess the quality of the sorting process and (b) the evaluation of the performance quality in the first six months of the training of the underlying artificial intelligence and its database.

Abstract The paper presents examples of installations for the mechanical and biological treatment of municipal waste in Poland. Each of the presented installations is defined as a regional municipal waste treatment installation (RIPOK). Their technological solutions and work efficiency have been compared in this study. In addition, the loss of waste mass as a result of processes occurring in the biological part of individual installations was calculated in the research. The paper refers to the National Waste Management Plan (KPGO 2022) regarding the circular economy. As intended by the circular economy, MBP installations will be transformed into installations that will treat selectively collected municipal waste and become Regional Recycling Centers (RCR).

Waste Treatment Plant

Construction of Technosols offers interesting alternatives to two current problems in the city of Vitoria-Gasteiz (Spain): waste recycling and degraded plot recovery. To evaluate the viability of their use, 6 types of Technosols were created by mixing four different byproducts from municipal waste treatment plants. The less than 40 mm size fraction material from the municipal construction and demolition waste treatment plant was used as the main ingredient, bio-stabilized material from the solid urban waste treatment plant mixed with triturated pruning was used as organic matter input, recycled bentonites and topsoil from the public plots of Vitoria-Gasteiz (Spain) completed the mixture. Mixes were prepared in triplicate and installed in 48 m<sup>2</sup> cells along with another 4 control cells containing only one of the ingredients at the municipal landfill of Gardelegui. A monitoring program for different parameters on soil, eluates and natural leachates was established to test the Technosols’ capacity to sustain vegetation without negative impacts on the environment. The final objective is to test their ability to restore unused municipal plots. Results from the first year show that Technosols are a suitable option for degraded sites restoration and green infrastructure support. All controlled parameters on soil are within the limits set by autonomic legislation for land use as public park. The eluate analysis concludes for all studied parameters that all mixes would be classified by legislation as inert waste, except for the sulphate concentration (which exceeds the inert waste limit of 1 000 ppm), that currently would label the soil as non-hazardous. In the natural leachate analysis strongly basic pH values were present above 9.5, the limit allowed in Royal Decreet 849/1986, but acidified throughout the year moving towards neutrality, with final values between 7.31 and 7.51. Leachate from CDW30, TS15 and RB30 Technosols showed not allowed values with respect to sulfates and Fe during the last sampling, surpassing the limits of 2 mg/l and 2000 mg/l respectively. All studied Technosols presented a low ecological potential risk (RI &lt; 150) for heavy metals in soil and eluates.

Waste Treatment Plant

This article presents the technological processes associated with waste management on the example of the Municipal Waste Treatment Plant in Olsztyn. Legal acts regulating waste management and the maintenance of cleanliness at the municipal level are discussed. The Municipal Waste Treatment Plant in Olsztyn processes waste from 37 municipalities in the Region of Warmia and Mazury. Waste transported to the plant is separated into sorted waste and mixed waste which undergoes further processing. An innovative solution in the country of drying waste mixed in bioreactors, where aerobic biodegradation occurs, was applied in Olsztyn. As a result of the temperature in this process, the waste is dried without additional energy from the outside. Processed waste is used in the production of alternative fuel. Around 5-15% of the collected waste is not fit for processing, and it is landfilled.
