Most of the systems for the mechanical and biological treatment of waste used in Poland send the 0–80 mm fraction separated from the municipal waste stream, after biostabilization, entirely to a landfill. Such action is not in line with the adopted EU strategy focused on waste management in the circular cycle. The purpose of this work was to assess the technical feasibility of recovering the mineral fractions contained in compost-like-output (CLO) on the proprietary technological line designed for glass recovery. The research was launched in January 2019, and lasted for a subsequent 12 months. In the article, the amounts of mineral fractions possible to be separated from CLO are presented, as well as their morphological composition and selected properties being determined. The processing of CLO on the line allowed to recover on average 69.4 ± 7.0% of the glass. This product was accepted by glass recycling plants. Mineral fractions constituting waste from the glass separation process were tested for their use in winter road maintenance. Tests were also carried out confirming the possibility of using selected mineral fractions (0–10 mm) from CLO to obtain a waste cement mix useful for constructing road foundations using a standard amount of cement.

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).

Multiple Challenges

The growing population and rising standards of living lead to an increase of the consumption of many goods. Reducing municipal waste which is created in that process can result in a wide range of environmental, economic, and social benefits, such as reducing pollution in water and soil, greenhouse gas emissions and loss of valuable materials. The concept to solve this problem of municipal waste due to increased consumption can be found, among others, in circular economy (CE). Circular economy can be defined as “an economic system that is based on business models which replace the ‘end-of-life’ concept with reducing, alternatively reusing, recycling and recovering materials in production/distribution and consumption processes to accomplish sustainable development” (Kirchherr, Reike, & Hekkert, 2017). A current trend in developed countries is closing the loop, moving from the concept of “end-of-pipe” waste management towards more holistic resource management (Wilson, 2007). Implementing the circular economy approach through waste management systems can pose multiple challenges while providing incentives to improve waste management infrastructure. However, this requires investments and may be perceived by many people as cost, not investment in future generations and their standard of living. The aim of this chapter is to initiate discussion on the positive aspects and barriers of circular economy development in the Polish waste management sector. In the case study described in the text, the roles of citizens, public institutions as well as enterprises are shown in selective waste collection processes as an important element of circular economy. In Poland, awareness of waste segregation and the importance of using recycled materials is not well-developed compared to many other EU countries, although this situation is beginning to gradually improve.

Made In

Since 2018, the economic regulation of Italian municipal waste utilities is attributed to an inde-pendent authority, ARERA. This original model is supposed to facilitate the transition towards the circular economy paradigm, that associates demanding public service obligations to recy-cling and valorization of waste, in the context of a vertically-integrated industry with a wide differentiation of conditions and maturity throughout the country. This paper analyzes the ex-perience of the first two years and discusses the outcomes reached. We start from a discussion of the fundamental economic characteristics of the waste management industry and of how the circular economy paradigm has radically changed it, raising rather new regulatory issues. We next analyze the structure of the Italian municipal waste management industry and its trajecto-ries of evolution face to the challenge to achieve the demanding targets imposed by the EU Circular Economy Package. We present then the regulatory approach adopted by ARERA in the first regulatory period (2020-2021) and discuss its advantages and drawbacks, based on the experience made in the early phase of its implementation.

The Impact

Municipal waste management system modeling based on the mass balance of individual waste streams allows us to answer the question of how the system will react to organizational changes, e.g., to the expected reduction in the amount of plastics or the introduction of a deposit for glass and/or plastic packaging. Based on the data on Polish municipal solid waste and the forecast of changes in its quantity and composition, as well as demographic data, a balance model was prepared to assess the impact of introducing higher and higher levels of recycling, in accordance with the circular economy assumptions on the waste management system. It has been shown that, for the Polish composition of municipal waste, even if the assumed recycling levels of individual streams are achieved, achieving the general target level of 65% recycling in 2025/30 may not be feasible. The possibility of achieving a higher level of recycling will be possible due the introduction of selective ash collection from individual home furnaces, while the impact of reducing the amount of plastics or introducing a deposit on packaging is minimal. The calculations also showed that, to complete the waste management system in Poland, we need at least 3.5 million Mg/year of incineration processing capacity and the present state (approx. 1.3 million Mg/year) is insufficient.

Municipal Waste Management

Municipal waste management has been an area of special interest for the European Commission (EC) for many years, especially in the transformation process towards a circular economy (CE), which is a priority of the European Union’s (EU’s) economic policy. This paper presents the overview of the Polish waste management system (WMS) and the CE-related tasks indicated in the Polish CE Roadmap. Despite the fact that Poland is one of the countries that generates the least waste per capita (329 kg in 2018) in the EU (489 kg), it still has problems with adapting the levels of municipal waste recycling to European requirements (34.3% in 2018, EU average 47%), which result from the lack of sufficient infrastructure for waste management and the insufficiently developed public awareness and behaviors. The current paper presents an inventory of the recommended actions, which support transformation towards CE in municipal waste management. These actions have been grouped into six core principles of circularity, indicated in the ReSOLVE framework: Regenerate, Share, Optimize, Loop, Virtualize, and Exchange. In each of presented areas, recommended tasks and actions were identified that should be taken by governments and residents themselves, such as landfill remediation, use of selected municipal waste fractions for economic purposes, sharing products with co-users, waste recovery, remanufacturing products or components, virtual solutions in everyday life to reduce the amount of generated waste, or replacement of household appliances by items with a higher energy class. An implementation of specific actions indicated in the paper could positively influence transformation towards CE in Poland. Because the presented examples of actions are model solutions, they can also be used in other countries and regions.

Waste Management Policy

Municipal solid waste management is an environmental issue that has received considerable attention from researchers and environmental managers for decades. Supporting the management programs entail policies and regulations related to municipal solid waste. In developed countries, the implementation of environmental policies plays an important role and has a substantial impact on the effectiveness of solid waste management. However, in many developing countries such as Vietnam, the situation and effectiveness of the policy implementation have not been studied extensively. This investigation is conducted to ascertain the situation, limitations, and challenges in implementing solid waste management policy in Vietnam. Then, solutions for the problems and improvements for implementation efficiency are presented. This work used online questionnaires to survey environmental managers in different localities and applied qualitative research method to analyze data. The results show that not all national policies on solid waste management are implemented in all localities. Waste separation is also the foremost concern in municipal waste management in most localities of Vietnam. Most of the localities claimed that the unrealistic nature and difficult implementation of the policies and the lack of needed resources are the main limitations and challenges in Vietnam. Survey results also revealed that different localities in Vietnam have different solutions to increase policy implementation efficiency. Besides, the study also found similarities in the implementation of policies in solid waste management between Vietnam and some other countries and also gathered some valuable lessons for the improvement strategy. Finally, the implementation of an effective domestic solid waste management policy is an important platform for improving environmental quality and ensuring the sustainable development of the nation and mankind.
