  • NovaGerar landfill gas to energy project

    Overview The objective of the NovaGerar Landfill Gas to Energy Project in Nova Iguaçu - Rio de Janeiro, Brazil is to explore the landfill gas (LFG) collection and utilization activities of the landfills managed by S.A. Paulista. This involves investing in a gas collection system, leachate drainage system and a modular electricity generation plant at each landfill site (with expected ...

  • Modified landfill design for sustainable waste management

    Waste management, being one of the most important aspects of urban development, is gaining importance among developing nations. Landfills, which were initiated for hazardous waste management and subsequently transformed into sanitary landfills, have been the most widely adapted practice for municipal solid waste management worldwide. However, the conventional design of landfills not only fails to ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Waste to energy plants – management issues and current practices

    Though open waste dumping has long back disappeared in the developed world ,it continues to be an eye-sore and environmental threat in many parts of the developing world. Landfills are becoming a common practice despite opposition from local community groups as well as NGOs for various reasons. However better equipped landfill facilities with provision for methane capture is being viewed as an ...

  • Measuring and interpreting gas flow from landfill boreholes case study

    Current landfill gas measurement practice for measuring the gas composition is well understood, and there are standard procedures and instruments available to analyse the gas. It is also current recognised practice to measure the gas 'flow' from boreholes to monitor the production of gas in a landfill site. If care is taken to make the measurement in the same way each time, changes in the ...

  • Landfill Leachate Sources and Treatment Options

    What is leachate? In a lab, it is any liquid that extracts solids as it passes through matter. In a landfill, it is the water that enters the facility in a number of ways, passes through waste material on contact, contains a wide range of constituents, and must be addressed with a proper operations plan. Leachate treatment options and mitigation are one of the greatest costs for landfill ...

  • Off-Gas Treatment Technologies for Soil Vapor Extraction Systems: State of the Practice

    Untitled Document EXECUTIVE SUMMARY This document provides state-of-the-practice information on off-gas treatment technologies for soil vapor extraction ...

  • Estimating national landfill methane emissions

    This paper estimates national methane emissions from solid waste disposal sites in Panama over the time period 1990–2020 using both the 2006 Intergovernmental Panel on Climate Change (IPCC) Waste Model spreadsheet and the default emissions estimate approach presented in the 1996 IPCC Good Practice Guidelines. The IPCC Waste Model has the ability to calculate emissions from a variety of solid ...

  • Zero Waste to Landfill Goal: Portland Aluminium

     Portland Aluminium has achieved a significant reduction in the amount of waste going to landfill. Although driven primarily by business needs including the pursuit of efficiencies, waste reduction has been achieved by evaluating processes, gaining the commitment of its workforce and combining these efforts with both cleaner production and waste minimisation concepts. ...


  • Landfills have a huge greenhouse gas problem. Here’s what we can do about it.

    We take out our trash and feel lighter and cleaner. But at the landfill, the food and yard waste that trash contains is decomposing and releasing methane, a greenhouse gas that’s 28 times more potent than carbon dioxide. Landfill gas also contributes to smog, worsening health problems like asthma. Globally, trash released nearly 800 million metric tons (882 million tons) of ...

  • Greenhouse gas emissions from waste management-assessment of quantification methods

    Of the many sources of urban greenhouse gas (GHG) emissions, solid waste is the only one for which management decisions are undertaken primarily by municipal governments themselves and is hence often the largest component of cities’ corporate inventories. It is essential that decision-makers select an appropriate quantification methodology and have an appreciation of methodological ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Sustainable management of household solid waste

    In most countries, the majority of household solid waste is landfilled because of associated low capital, operation and maintenance costs. However, many existing landfills have exhausted their handling capacities and new facilities are faced with the problem of siting. Alternatives to traditional landfill practice are required to achieve sustainability in managing solid waste. This manuscript ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Long-term leachate emissions from municipal solid waste landfills sre unknown

    The Swiss have always been highly environmentally aware, and for a long while have looked after their environment in an exemplary fashion. The 'Guidelines to waste management in Switzerland' ( EKA, 1986 ) were set in 1986, well ahead of many states. One necessary objective of this as a code of good practice has been that all waste management procedures have to provide materials which either are ...


  • Management of Hazardous Wastes

    ' Management of hazardous waste is a growing concern in many countries. The long-term impacts and costs of improper disposal can be very high and the emphasis must be on prevention. A comprehensive management system should include (i) policies, institutions and effective regulations and (ii) adequate and acceptable disposal facilities (either public or private). This note outlines the key ...

  • Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water

    Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other ...

  • Demonstrating advanced environmental management

    Everyone has high expectations when it comes to maintaining the environment. But for Castle Cement, just meeting those expectations wasn't enough. Managing stakeholder expectations is a major challenge for those implementing environmental management systems (EMS). Increased demands for transparency are driving process-based management systems and the rise in public reporting of environmental ...
