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).

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.

The purpose of the study presented in this text is to show the influence of COVID-19 on waste management systems and circular economy stream, and their impact on circular economy, particularly the economic impact of the pandemic on the waste management sector, impact on circular economy objectives’ implementation as well as additional challenges like the need for hygienization of waste streams during different implementation efforts, such as changes in the municipal solid waste market and different waste processes of their disposal. Additionally, some methods—such as thermal treatment—which seemed to be not fully aligned with the circular economy approach have advantages not taken into account before. Incineration of higher volume of waste affects the waste structure and will change some of the circular economy objectives. The analysis was carried out on the example of the Polish market.

Dustbins (or Garbage Bins, Trash Cans, whatever you name them) are small containers of plastic or metal used on a temporary basis to store trash (or waste). They are also used for the collection of waste in houses, workplaces, highways, parks, etc. Littering is a major crime in some countries, and public waste bins are also the only way to dispose of small waste. Usually, using different bins for handling wet or dry, recyclable or non-recyclable waste is a common practice. From an ETS perspective, smart waste collection can help municipalities and private waste management companies avoid the need for collection sites, waste disposal facilities and waste treatment plants. As communities increasingly rely on smart city technology to improve, among other things, the quality of life of their residents and the environment, city leaders recognize that smart waste management can also help them achieve sustainability goals such as zero waste and improve services to residents, while improving service to residents. As an example, Development of Some solar-powered bins and recycling bins are already equipped with sensors that analyze data on what is disposed of or recycled and notify collectors when the bin is too full and needs to be picked up. These developed Smart waste management solutions use sensors placed in waste bins to measure levels, notify municipal waste collection services, when the bins are ready to be emptied, and also notify municipal waste collection with a ton has been emptied. Therefore, the solar-powered of sensors based smart waste monitoring system is more and more useful to the current smart cities policies under the smart city project works.

The Impact

Municipal waste treatment is inherently associated with odour emissions. The compounds characteristic of the processes used for this purpose, and at the same time causing a negative olfactory sensation, are organic and inorganic sulphur and nitrogen compounds. The tests were carried out at the waste management plant, which in the biological part, uses the methane fermentation process and is also equipped with an installation for the collection, treatment, and energetic use of biogas. The tests include measurements of the four odorant concentrations and emissions, i.e., volatile organic compounds (VOCs), ammonia (NH3), hydrogen sulphide (H2S), and methanethiol (CH3SH). Measurements were made using a MultiRae Pro portable gas detector sensor. The tests were carried out in ten series for twenty measurement points in each series. The results show a significant impact of technological processes on odorant emissions. The types of waste going to the plant are also important in shaping this emission. On the one hand, it relates to the waste collection system and, on the other hand, the season of year. In addition, it has been proved that the detector used during the research is a valuable tool enabling the control of technological processes in municipal waste processing plants.

Although waste management has long been an important economic sector, its employment effects have so far been neglected in economic calculations. Recently, employment effects have been addressed in the European Green Deal or the Climate Neutrality Strategy. A scientific calculation is, however, still missing. To close this gap, our paper develops a set of alternative models as to residual waste treatment and investigates their potential to produce direct employment effects. The models include employment required for treatment plants plus employees needed in collection and transports. The models range from basic to sophisticated, from unregulated landfilling via 100 % waste incineration to mechanical-biological treatment to improved separate collection and advanced recycling. Data for devising these models were derived from a secondary analysis (e.g. residual waste analyses of the Austrian provinces) and from expert interviews. Although the models are simplified and build on generic waste management systems, they allow for a rough estimation of employment effects: The more sophisticated the waste management system, the more employees are necessary. In all models, but especially in improved separate collection, collection accounts for a significant part of the additional employment. The models show an increase in employment many times over with the improved separate collection model compared to the other models. Although our results can only be scaled up to European Union level in a limited way, we can state that shifting from less sophisticated waste management models to more desirable ones can involve an increase in employment of at least some 40.000 jobs.

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.

Most of the radioactive wastes generated in Romania, are due to nuclear activities related to power generation at Cernavoda Nuclear Power Plant NPP Unit 1 and Unit 2. It is provided to construct 2 new Units, in the next period. In Romania, the Nuclear Agency & Radioactive Waste - AN&DR, has established the strategy on low and intermediate level waste disposal and has as objective the commissioning of Final Repository for Low and Intermediate Level Waste – DFDSMA, until 2019. This facility, is in the responsibility of AN&DR. On the other hand, wastes arising from Cernavoda NPP must be treated, in order to achieve the acceptance criteria of DFDSMA. Corresponding Radioactive Waste Treatment Plant - RWTP is in the responsibility of Cernavoda NPP. The main requirement for the RWTP is the necessity to achieve the treatment and conditioning of radioactive wastes that arise both, from NPP operation and from future decommissioning activities of the nuclear facilities, such as to comply with the acceptance criteria of DFDSMA. According to existing requirements, it is necessary to elaborate a Decommissioning Plan, in order to obtain the authorization for construction of the new units. The Decommissioning Plan of Cernavoda NPP will imply the development of a Waste Management Plan, based on existing waste treatment technologies. Taking into account that, the radioactive waste management represents about 43%, comparative with decommissioning activities, which represents only about 35% from total budget of decommissioning, of a CANDU 6 NPP Unit, the paper will present the methodology developed, in order to obtain the optimum Waste Management Plan, taking into account the reduction of environmental impact.

The scientific objective of this study is to develope a methodology for the investigation of municipal solid waste (MSW) composition in Lithuania. Investigations have been performed in Kaunas, which is the second large city of Lithuania. The obtained results are a contribution to assess, evaluate, and predict possible development scenarios of the municipal waste management sector in east European countries. Possible scenarios consider improved separate collection systems in combination with landfilling, mechanical-biological treatment and/or incineration. Further the results provide scientific knowledge which is necessary to understand waste generation and composition. This information is crutial to avoid future emissions to the environment resulting from current waste treatment practice. A further aim is to better understand the interplay of natural, social and economic factors influencing the quality and quantity of MSW in Eastern Europe. In this paper we present the preliminary results of consecutive MSW analysis at the waste collection and transfer station in Kaunas City over a period of two years.

Sorting System

The tremendous quantity of waste produced from construction and demolition is a major cause of environmental degradation. This quantity tends to increase due to the rapid growth of building development and renovation. Meanwhile, construction waste management is a complex and costly process due to the fact that it requires different kinds of resources such as money, land, and technology. It is often ignored by all project participants even though it is an essential element of construction project management. However, it has been discovered that modern construction waste management is structured based on the concept of circular economy which focuses on eliminating construction waste and maximizing the value of materials. Therefore, this research proposes an innovative framework to implement the circular economy using building information modeling (BIM) in order to improve the construction waste management process. This involved a thorough review of past literature to identify the implementation of the concept of circular economy, waste management, and the application of BIM, also the research gaps observed were used to develop the functionality of the proposed framework. The five functionalities include (1) visualization and data integration, (2) direct construction waste quantity take-off, (3) BIM-based sorting system and selection of appropriate disposal parties, (4) estimating cost and schedule of waste disposal, and (5) simulation and monitoring report. This BIM system was designed to analyze material waste, quantity, disposal time, and waste treatment based on project conditions, material quantities, and schedule. It can also be used to plan and monitor the construction waste process, thereby making it possible to avoid the disruption of productivity and project time usually caused by unplanned waste management activities. Moreover, the proposed on-site sorting system also has the ability to facilitate the adoption of the circular economy concept during the construction phase.
