  • Disposal options for solid waste of Bangalore city based on its characteristics

    A detailed analysis of Bangalore's solid waste has been done to suggest various management options for safe disposal. It has been observed that Bangalore's solid waste contains a larger proportion of degradable waste compared to many other cities. Based on detailed analysis of available data, it has been suggested that a landfill with a leachate and gas collection system is better than an inert ...

  • 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 ...

  • Hazard assessment of waste disposal sites. Part 1: literature review

    A review of the literature and computer models from the perspective of hazard assessment approaches, particularly relating to the risk analysis of waste disposal sites, has been carried out. It was found that a comprehensive hazard assessment procedure covering all modules and sub-modules for landfill leachate does not exist. The same deduction also applies to landfill gas and degraded landfill ...

  • Deep in the Dumps? How municipalities can avert a waste disposal crisis

    Municipalities across Canada are looking for economical and environmental methods to improve their waste management diversion methods. Some are scrambling to assess and extend landfill disposal capacity and others are trying to dramatically increase their diversion rates. Many are initiating a combination of strategies. Canada's largest city has arguably received the most attention with regard to ...

  • Several waste gas streams: Highly contaminated oxygen-free waste gas, and medium waste gas stream - Case Study

    Example: Chemical industry Similar tasks: Petrochemical and pharmaceutical industries A producer of synthetic rubber creates a medium waste gas as well as a highly contaminated oxygen-free waste gas which contains primarily low hydrocarbons. The main waste gas stream is purified in a regenerative thermal oxidiser (RTO), while the oxygen-free waste gas passes through ...

  • Comparison of cost estimates of final disposal facilities for carbon dioxide and high–level radioactive waste

    This paper presents new research and new cost calculations for carbon dioxide (CO2) disposal in Cuba and Lithuania, as well as lessons from the comparative assessment of CO2 and high–level Radioactive Waste (RW) disposal costs in several countries. Nuclear power and CO2 Capture and Disposal (CCD) ...

  • Role of final cover soil in regulating volatile organic compounds: emissions from solid waste disposal sites in developing countries

    The objective of this study was to investigate the emission of Volatile Organic Compounds (VOCs) from solid waste disposal sites and their remediation at final cover soil. This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. It was found that benzene, toluene, chloroform and perchloroethylene ...

  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • The 1998 PCB Disposal Amendments: Guide to the 1998 PCB "Mega Rule"

    INTRODUCTION On June 29, 1998, the U.S. Environmental Protection Agency (EPA) promulgated a sweeping series of changes in the PCB regulations under the Toxic Substances Control Act (TSCA). Commonly known as the Mega-Rule or PCB Disposal Amendments (due to its focus largely on waste management issues), this long-awaited rule encompasses more than 80 changes in the regulations and spans more ...
