Emission of volatile organic compounds from solid waste disposal sites
The emission of volatile organic compounds (VOCs) from a solid waste disposal site for municipal solid wastes was quantified. The VOCs contained in the landfill gas taken at the site were benzene, toluene, xylenes, ethyl benzenes, and trimethyl benzenes, while the concentrations of chlorinated compounds were very low. The concentration of benzene in the landfill gas samples ranged from below the ...

Dual role of hydrolysis coefficient in modelling of bioreactors
To the authors' knowledge, there is no published work, relating biodegradation and settlement of municipal solid waste (MSW) in bioreactor landfills together. The present mathematical model is developed to simulate the biodegradation of MSW in anaerobic bioreactor landfills and predict the strength of leachate in terms of volatile fatty acid (VFA). The hydrolysis rate constant (kh) has been found ...

Comparative assessment of anaerobic digestion of municipal solid waste at mesophilic and thermophilic temperatures
Anaerobic digestion is an environmentally sound treatment option for the organic fraction of municipal solid waste (OFMSW) and simultaneously producing methane gas which is a source of renewable energy. The COD reduction of the substrate was 72% for the mesophilic condition and 72.3% for the thermophilic condition. 1200 cm³ of methane was produced in the mesophilic condition and 1260 cm³ in the ...

Contingent Valuation of improved waste management: the case of a tourist town in a developing country
This paper reports on a Contingent Valuation (CV) study of improved solid waste management in Boca Chica, Dominican Republic. CV is a survey-based method of economic valuation of public services, and it was applied to assess residents' Willingness-To-Pay (WTP) for two alternative improvement plans. Three hundred heads of household were interviewed. After responding to questions about the actual ...

Utilisation of municipal solid waste as an amendment for reclamation of coal mine spoil dump
Mine spoil dumps generated due to mining activities pose drastic physico-chemical and biological constraints for sustainable vegetation. Thus an eco-friendly and cost-effective Microbe Assisted Phytoremediation (MAP) is adopted for reclamation of coalmine spoil dumps. The results indicate that MAP is also an excellent tool for fast restoration and productivity of wastelands, 95?99% plants ...

Home composting of organic waste - part 1: effect of home composter design
Worldwide, health and environmental considerations encourage landfill diversion of the organic fraction (OW) of municipal solid wastes, through alternative such as home composting. Of poor sanitation, and trace element and toxic hydrocarbon content (PAH) documentation, this study compared against a laboratory composter (LR), the performance (temperature regime and compost quality) of four 300 to ...

Occupational health hazards of the working group associated with municipal solid waste management at Kolkata in Eastern India
The reasonable concern of many developing nations (India) is the presence of Municipal Solid Waste (MSW) workers (ragpickers in particular) who scavenge garbage bins and landfill areas to salvage recyclable materials. In order to examine the health of the working group associated with MSW disposal, a study was conducted among the conservancy staff and ragpickers. The demographic and ...

Performance study for anaerobic digestion of municipal solid waste in a single phase reactor
Anaerobic Digestion (AD) has been up to now essentially applied to wastewater. However, anaerobic treatment of organic solid waste fits well with the new requirements for waste management. A batch study of vegetable market waste composed at various solid concentrations was studied in a single phase anaerobic reactor. Prior to this, studies were also carried out in aspirator bottles of different ...

The MEFLO method`s application for the feasibility assessment of energy recovery from municipal solid waste in a small integrated municipal service system
The paper presents the MEFLO ranking method and the Simple Integrated System Management (SISMan) concept for assessing the feasibility of integrated energy and Waste Management System (WMS) alternatives. The MEFLO method is based on dividing the decision-making process into five modules, including mass, energy and financial flows, legislative criteria (e.g., environmental restrictions and target ...

The reduction of greenhouse gas emissions using various thermal systems in a landfill site
In this paper, the Greenhouse Gas (GHG) emissions from an uncontrolled landfill site filled with Municipal Solid Waste (MSW) are compared with those from controlled sites in which collected Landfill Gases (LFG) are utilised by various technologies. These technologies include flaring, conventional electricity generation technologies such as Internal Combustion Engine (ICE) and Gas Turbine (GT) and ...

Electrical and electronic waste inventory and management strategies in Bangkok, Thailand
This study investigates the current situation of e-waste management in Bangkok, Thailand. Information on prevailing situation was collected through interviews, surveys, questionnaires and field visits. The e-waste inventory methodology was developed for estimating e-waste generation. About 90,000 tonnes/year of e-waste was estimated to generate from households in 2003. The major contributor of ...

Municipal Solid Waste Recycling: 2020 Easy Explanation
Municipal Solid Waste (MSW) also known as trash or garbage—consists of our everyday items we use and then discard. This is a generic name for product packaging, biomass trimming, furniture, appliances, paint, wires, batteries, clothing, bottles, food scraps, books and newspapers. Such waste obviously comes from households, schools, shops, businesses, hospitals, factories and construction ...

A comprehensive evaluation of solid waste management in Kuwait
One of the major problems facing a nation is the need for the proper disposal of the voluminous of solid waste generated every year. Therefore, recent literature on solid waste management in Kuwait has been reviewed and data analysed on the total amount of solid waste generated in Kuwait. In addition, industrial solid waste, construction and demolition waste, and pharmaceutical waste are ...

Economic evaluation of a landfill system with gas recovery for municipal solid waste management: a case study
Economic activity uses resources, which leads to waste generation. With rapid industrialisation and urbanisation, per capita solid waste generation has increased considerably. Solid waste generation data for last two decades shows an alarming increase. Owing to its improper and untimely collection, the transport and disposal of municipal solid waste poses a severe threat to various components of ...

Biomethanation of solid wastes: analysis of case studies
Management of the organic fraction of urban solid waste using anaerobic procedures will contribute to the reduction of greenhouse gas emissions, and using biogas, which is a carbon neutral energy, to generate electrical energy will eventually help in reducing the combustion of fossil fuel. Energy recovery in the form of biogas from Municipal Solid Waste (MSW) generated in three different ...

Landfill disposal of unused medicines reduces surface water releases
The pharmaceutical industry is conducting research to evaluate the pathways and fate of active pharmaceutical ingredients from the consumer to surface waters. One potential pathway identified by the researchers is the disposal of unused pharmaceutical products that are discarded by consumers in household trash and disposed of in municipal solid waste landfills. This study was designed to evaluate ...

Interval-fuzzy possibilistic mixed integer linear programming for environmental management under uncertainty
This paper introduces an Interval-Fuzzy Possibilistic Programming (IFPP) method to handle uncertainties expressed as interval values and fuzzy sets. An interactive algorithm is advanced for solving the IFPP model, which does not lead to more complicated intermediate submodels and has a relatively low computational requirement. A municipal solid waste management problem is then studied to ...
