Municipal waste management and Waste-to-Energy (WtE) potentials in New Zealand are discussed. The existing main waste management strategy of New Zealand is to reduce, reuse and recycle waste. Most of the remaining waste is currently disposed of in landfills. WtE options were explored in this study as a more sustainable waste treatment alternative in the country, while making use of the annual 30.8 petajoule of available waste energy in New Zealand. Four WtE technology options were discussed and compared, namely incineration, anaerobic digestion, gasification and pyrolysis. The aspects in comparison were air pollution, cost, side products, capacity, commercial maturity, energy efficiency and type of waste treated. Special emphasis was given to environment-friendliness and cost. From the comparison, it was found that anaerobic digestion seems to be the most attractive solution for the country as it is environment-friendly, economical and the concept is consistent with New Zealand’s existing waste management strategy. The major limitations of anaerobic digestion are its low energy production efficiency and its limited waste treatment capacity. Hence, an effective national waste reduction and recycling strategy is crucial for the success of this waste management option.

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.

In light of the organizational dynamics of services of economic interest, the regulation of municipal solid waste management is a critical issue to deal with so as to achieve sustainability goals in the coming decades. The European circular economy targets limit the share of municipal waste in landfills to a maximum of 10% by 2035. Consequently, waste-to-energy plants may temporarily become the primary option for residual unsorted waste. The municipal waste management chain comprises two consequential stages: collection and transport, and the treatment and disposal stage, which characterizes as an oligopolistic market structure. After defining the relevant market and calculating market concentration measures, we analyze market power in the treatment and disposal of non-recyclable mixed waste, also known as residual waste. Our analyses are based on empirical data using well-known market concentration indices such as the Herfindahl–Hirschman index and concentration ratios. We report the results of three different market concentration scenarios based on alternative geographic and product market definitions. Considering only waste-to-energy as a product market, we present a situation of moderate concentration, typically involving the attention of competition authorities. On the contrary, considering both options as a single product market, no relevant evidence emerges due to the significant share of waste sent to landfills in 2019, i.e., 20.1% of the total municipal solid waste generated in Italy. Implications for future studies consist of new detailed information on the municipal waste treatment market structure in one of the leading European countries that may prompt comparative studies. Policy implications are derived from the possibility of taking cues from this paper to envisage appropriate regulatory models for an evolving sector in which market spaces are increasing.

The paper discusses the current state of municipal waste management in Poland compared to other European Union countries. It indicates the amounts of municipal waste generated over the last few years in Poland and other EU countries. The paper compares waste treatment methods in Poland and Europe, such as recycling, composting, thermal treatment and waste disposal. An analysis of municipal waste processing installations in Poland is presented. The trends in the municipal waste management system in recent years have also been described. In the field of municipal waste management in Poland, there have been significant changes. The amount of waste sent to landfills has decreased, and the amount of waste recovered and recycled has increased. These changes are positive and reflect the development of municipal waste management systems in other EU countries. The article indicates the problems and directions of changes in the field of municipal waste management in Poland in the coming years, especially in the context of the implementation of circular economy assumptions and the goals set by the European Union in terms of increase the level of waste recycling and reducing their disposal.

Waste management is an emerging focus in Pakistan. Specifically, waste-to-energy (WtE) projects are conceived to obtain benefits from municipal waste collection in metropolitan cities. This study provides a brief background of WtE potential, waste collection statistics, type of generated wastes, and current measures to build the confidence of investors in WtE projects. In addition, a brief overview of government efforts for WtE and delineation of licensing requirements for power generation are discussed. The parameters laid down for the determination of tariffs for municipal waste management power projects and the cost accounted for each parameter are analyzed in detail. Similarly, this study deliberates on observations among stakeholders and compares Pakistan tariffs with those of neighboring countries.

The unprecedented urbanization that is occurring worldwide brings with it a vast amount of solid waste, leading to a rapid increase in study of municipal waste management (MWM) worldwide. This mini-review assessed this body of research both quantitatively and qualitatively. The data for the review were 9711 publications indexed by the Science Citation Index Expanded and the Social Sciences Citation Index for the period 2000–2019. The analysis showed that developed countries, the United States in particular, led trends in research during the first part of the period, and developing countries made substantial contributions to the literature more recently. For all years since 2009 except for 2014, China produced more research than the United States, becoming the most productive country in the study of MWM. Home to five of the ten most productive global research institutes on this subject, China is also a hub for collaboration among countries and institutes, as is the United States. Using content analysis and keyword visualization, this study characterized two decades of study of MWM. This study found that the keywords “sustainability,” “waste-to-energy,” “life-cycle assessment,” and “China” exhibited an upward trend in research. This study seeks the pathway to successful scientific research, helping guide researchers as they innovate in and contribute to the field, and proposes pathways that governments can take to build sustainable MWM systems.

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.
