A study of the plastics materials flow analysis in Thailand was aim to show the flow of plastic materials through production, consumption, and waste management based on the year 2013 and projection to the year 2020. This paper finds the plastic waste generation increasing steadily in line with population growth and increasing consumption. In addition, the simulation under waste management three scenarios includes the following: the business as usual, increasing recycled rate set on the National Solid Waste Management Master Plan (2016-2021) and increasing in rate of energy recovery by the Alternative Energy Development Plan 2015-2036. The plastic material flow analysis has shown that the implementation of the National Solid Waste Management Master Plan (2016-2021) or the Alternative Energy Development Plan 2015-2036 can reduce uncollected waste and improper waste disposal. Moreover, there is benefit by adding value from recycled materials and energy recovery.

Abstract This study presents solid waste management planning in an urban green area, Bangkok, Thailand based on the material flow analysis (MFA) and life cycle assessment (LCA). Global warming potential (GWP) of four scenarios for handling solid waste generated in Chulalongkorn University Centenary Park, 2018 was assessed concerning the different ratios of waste recycling, composting, incineration, and landfilling. The results show that alternative systems proposed will result in lower GWP than the existing waste management strategy. The MFA results reveal that the final weights of solid waste ending up in a landfill are 98.8, 101.9, 68.2, and 44.8 t yr− 1 for scenarios 1, 2, 3, and 4, respectively. Increased rates of landfill diversion by increased recycling, composting, and incineration decreased the quantity of solid waste disposed to the landfill and improved the environmental profile of the park waste management system. The LCA results found landfilling to be the dominant source of greenhouse gas (GHG) burdens, while waste recycling was found to result in the reduction of GHG. The results highlight that the use of MFA and LCA as a combined tool to evaluate the environmental performance of solid waste management systems provides valuable information for policy and decision-makers.

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.

Solid waste management system is becoming a significant environmental, economic and technological challenge due to the increasing population and different waste stream. Municipal solid waste (MSW) is easy to generate but difficult to venerate. The question of whether MSW is an undervalued resource or an environmental burden is in continual debate. This paper presents an overview and structure of the current MSW management in Hong Kong and the advantages of waste diversion when the waste that normally would be delivered to the landfill is removed from the MSW. This paper also studies the technology of energy recovery which can be achieved from MSW in direct combustion as a fuel to produce power and heat, or indirectly, through waste conversion to fuel or fuel in a state of storage for future use. The necessity, rationale and application of energy recovery facilities are discussed to meet public health and environmental concerns and the public’s desire and willingness to reuse and recycle waste materials. Solid waste management serves both resource recovery and waste disposal in the public’s future challenges and opportunities for change.

Solid waste management is commonly seen in Nigeria as simply pick up the waste and go dump it in a hole somewhere. Hence the current major solid waste management method in Nigeria is disposal at dumpsite. The solid waste management practice at the dumpsite is simple. The waste disposal trucks drive into the dumpsites through the access roads and dump their waste. Other vehicles that deliver waste to the site simply dump their waste indiscriminately by the road sides. The workers at the dumpsites use shovel to manually push the waste from the road and try to spread them as much as their strength can go. Thereafter, open air incineration without pollution control is carried out on the waste for volume reduction. This is not sustainable as it does not bring financial return at the end point of the waste. Therefore incineration with pollution control and energy recovery that will bring financial returns at the end point of the waste is ineviTable for sustainable solid waste management. In the work reported in this paper a study and preliminary design for incineration with energy recovery has been carried out. A review of solid waste component in Benin metropolis was carried out to determine the proportion of combustible material in the waste streams in the metropolis. Several conceptual designs were developed and one was selected. Detail design of a prototype for 15kW electrical power generation was done. The result obtained showed that about 43% of combustible commercial solid waste and about 16% of combustible domestic solid waste are generated in Benin metropolis. The result also showed that about 72Kg/s of combustible municipal solid waste is required for the generation of about 15kW of electrical power and the exhaust gas can be used for other process systems such as systems for drying agro-produce.
