Suitability assessment for handling methods of municipal solid waste
Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of waste are food waste (49.18%) and plastic (21.13%), and recyclable waste shares about 17.28% of the total. On average, it contains 60.92% moisture, 35.89% combustible, 3.19% ash, 58.32% carbon and 1.05% nitrogen. High calorific value is 10.03 MJ/kg when the low calorific value is 7.77 MJ/kg. The moisture content is too high to meet the technology demands, especially in the rainy season. It seems workable for incineration without energy recovery. Gasification for melting and incineration with energy recovery are only suitable for the dry season. If the solid waste is well pre-separated, material recovery could be one of the suitable handling methods. Food waste, wood and leave could be digested in the one-stage continuous wet system and co-composted, and plastic is appropriate for refuse-derived fuel generation. The current study recommends that the waste pre-separation should be requisite for any handling methods.
Due to increasing solid waste generation and their significant impacts on human health, environmental assessment of the management and disposal methods become more and more important. There are various disposal methods which are the combinations that originate from a wide range of solid waste management systems. In this study, municipal waste of Tehran (which totals to 7507.5 tons/day) is asses...متن کامل
This article examines how RFID (radio frequency identification) is poised to help transform the way we handle our trash our MSW (Municipal Solid Waste). We provide an overview showing that trash trends in the United States are not good, as modern life has meant increasing volumes of trash that can be disposed of in fewer and fewer landfills. We examine how RFID can be employed in the MSW area t...متن کامل
Collecting municipal solid waste (MSW) is a major and expensive task for local waste management authorities, thus efficient MSW collection is a necessity. This study presents a procedure for developing an aggregate indicator (AI) to assess MSW collection efficiency based on multiple factors. The applicabilities of various key performance indicators (KPIs) are evaluated based on five selection c...متن کامل
more garbage than any other nationover 160 million tons of garbage each year or more than 1,200 pounds per person. EPA expects this to increase to more than 2,300 pounds of garbage per person each year within the next 1 2 years. Whether it is recycled, buried or burned, the fate of this refuse has major impacts on public health, the environment and the economy. United States citizens generate W...متن کامل
The disposal of municipal solid waste into the landfills has been recognized as the major source of soil, surface water and groundwater contamination. Municipal solid waste disposal site for the city of Ludhiana, in Punjab, India, has become an overflowing landfill because of the indiscriminate dumping of solid waste at the site. The leachate produced by landfilling site contains a large amount...متن کامل
THE CITY OF COLOMBO , which has a resident population of little over half a million, and a total area of 3731 hectares, is administered by a Municipal Council. The collection and disposal of solid waste generated within the City is a function of the Municipal Council, and is carried out by its six district offices. The Colombo Municipal Council (CMC) collects around 500 metric tons of solid was...متن کامل
