Multidisciplinary Perspective

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.

Global Capacity

In this study, United States, China, India, United Kingdom, Nigeria, Egypt, Brazil, Italy, Germany, Taiwan, Australia, Canada and Mexico were selected to represent the global community. This enabled an overview of solid waste management worldwide and between developed and developing countries. These are countries that feature most in the International Conference on Solid Waste Technology and Management (ICSW) over the past 20 years. A total of 1452 articles directly on solid waste management and technology were reviewed and credited to their original country of research. Results show significant solid waste research potentials globally, with the United States leading by 373 articles, followed by India with 230 articles. The rest of the countries are ranked in the order of: UK > Taiwan > Brazil > Nigeria > Italy > Japan > China > Canada > Germany >Mexico > Egypt > Australia. Global capacity in solid waste management options is in the order of: Waste characterisation-management > waste biotech/composting > waste to landfill > waste recovery/reduction > waste in construction > waste recycling > waste treatment–reuse–storage > waste to energy > waste dumping > waste education/public participation/policy. It is observed that the solid waste research potential is not a measure of solid waste management capacity. The results show more significant research impacts on solid waste management in developed countries than in developing countries where economy, technology and society factors are not strong. This article is targeted to motivate similar study in each country, using solid waste research articles from other streamed databases to measure research impacts on solid waste management.

Waste To Energy

Thermal technologies, such as gasification, pyrolysis, waste-to-energy (WTE), and advanced thermal recycling (second generation WTE with the most advanced air emission control system), can be employed to recover energy from municipal solid waste (MSW), reduce the volume of material to be landfilled, and lessen the potential emission of methane. Methane is a potent greenhouse gas and a major component of landfill gas. All operating WTE facilities in the United States have been subjected to strict environmental regulations since the passage of the Clean Air Act Amendments in 1990. As a result, U.S. WTE facilities now meet or exceed stringent local air quality standards, including those imposed by the South Coast Air Quality Management District (SCAQMD) in Southern California. The United States Environmental Protection Agency (EPA) recognizes the important role of WTE in the integrated solid waste management and ranks combustion higher than landfilling in its solid waste management hierarchy. In addition to upstream source reduction and recycling, downstream thermal treatment of the residual MSW (conducted in controlled environment) can effectively recover energy and further reduce waste volume. Despite all the advantages and environmental benefits of thermal technologies, its utilization for treating MSW in California still faces many challenges. These include negative public perceptions, economical disadvantages, local marketability of by-products, and disposal options for residuals. This paper discusses the need to include energy recovery in the integrated MSW management in California and the challenges encountered by many local jurisdictions.

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.

Municipal Waste Management

Waste production is greater every year with society evolution. The same problem is also in Slovak republic, but Slovakia is significantly behind other developed countries in municipal waste management especially in area of energy utilization and recovery of the municipal waste. This problem will be totally reflected after the ban of the waste dumping in landfills. This work solves the problem of waste management in the Žilina region of Slovakia. Žilina region produces approximately 185000 tons of municipal waste. At present there is the majority of the waste dumped in the landfills. Large part of this waste could be energy utilized. Except municipal waste can be also used other types of the waste for the energy utilization. The paper evaluates energy potential of municipal waste in Žilina region. During the work it was determined the ratio composition of the waste in the Žilina region. There were measured gross calorific value, low calorific value and humidity on the waste samples. Based on these results it was determined energy potential of the municipal waste in the Žilina region. This energy potential could provide part of the heat and electricity for the Žilina region after using appropriate methods of thermal disposal.

Waste management in the United States presently has the following major three dimensions: Sanitary landfills, recycling, waste to energy predominantly based on the technologies of mass bum technology or refuse derived fuel. These three dimensions have undergone significant evolution during the past three decades. The design of sanitary landfills has evolved to include environmental protection features such as bottom liners, leachate collection systems and landfill gas management systems. Material recycling programs, many based on materials recycling facilities, have become more prevalent. Approximately 100 operating waste to energy facilities (“Facilities”) now exist in the United States. Improvements in the air pollution control systems incorporated in the Facilities have significantly lowered their air emissions. A fourth dimension, waste gasification technology, is evolving as a viable component of a waste management system and the hydrogen energy economy.

Subject. In the twentieth century, the most developed countries formed a permanent military economy represented by military-industrial complexes, which began to perform almost a system-forming role in national economies, acting as the basis for ensuring national security, and being an independent military and political force. The United States is pursuing a pronounced militaristic policy, has almost begun to unleash a new "cold war" against Russia and to unwind the arms race, on the one hand, trying to exhaust the enemy's economy, on the other hand, to reindustrialize its own economy, relying on the military-industrial complex. Objectives. We examine the evolution, main features and operational distinctions of the military-industrial complex of the United States and that of the Russian Federation, revealing sources of their military-technological and military-economic advancement in comparison with other countries. Methods. The study uses military-economic analysis, scientific and methodological apparatus of modern institutionalism. Results. Regulating the national economy and constant monitoring of budget financing contribute to the rise of military production, especially in the context of austerity and crisis phenomena, which, in particular, justifies the irrelevance of institutionalists' conclusions about increasing transaction costs and intensifying centralization in the industrial production management with respect to to the military-industrial complex. Conclusions. Proving to be much more efficient, the domestic military-industrial complex, without having such access to finance as the U.S. military monopolies, should certainly evolve and progress, strengthening the coordination, manageability, planning, maximum cost reduction, increasing labor productivity, and implementing an internal quality system with the active involvement of the State and its resources.

Climate change litigation has emerged as a powerful tool as societies steer towards sustainable development. Although the litigation mainly takes place in domestic courts, the implications can be seen as global as specific climate rulings influence courts across national borders. However, while the phenomenon of judicialization is well-known in the social sciences, relatively few have studied issues of legitimacy that arise as climate politics move into courts. A comparatively large part of climate cases have appeared in the United States. This article presents a research plan for a study of judges’ opinions and dissents in the United States, regarding the justiciability of strategic climate cases. The purpose is to empirically study how judges navigate a perceived normative conflict—between the litigation and an overarching ideal of separation of powers—in a system marked by checks and balances.
