In this research, Chapter 1 is dedicated to analytical evaluation of landfill gas recovery. The majority of the world's municipal solid waste in is still going to the landfills, US being no exception. According to BioCycle and Earth Engineering Center, about 270 million tons of waste are landfilled annually in US. Anaerobic degradation, a naturally occurring process on the landfills, generates ...

SUMMARY: Investigations into landfill simulation reactors and a full scale landfills are used for predicting emissions from municipal solid waste landfills. In the present study the water flow and solute transport through a landfill simulation reactor and a full scale landfill (using the same waste) has been investigated. The results indicate that, due to preferential flow pathways the water fl...

Municipal Solid Waste (MSW) is complex refuse consisting of various materials with different properties. Some of the components are stable while others degrade as a result of biological and chemical processes. Leachate resulting from this is hazardous pollutant to the soil and ground water underlying. Leaching of this leachate and heavy metals into the soil leads to the contamination of both so...

Prediction of biodegradation processes for the organic fraction of municipal solid waste is an issue of paramount interest for efficient landfill design and management. This paper presents the results obtained from an extended field work developed in a time period of ten years. Solid waste samples from a landfill were collected at different depths in 5 holes with depth of 17 m, and analyzed in ...

The municipal waste management system of the region of Irkutsk is described and a life cycle assessment (LCA) performed to assess the environmental performance of the system. Annually about 500 000 tons of waste are managed. The waste originates from three sources: household waste (27%), commercial waste (23%) and office & institutional waste (44%). Other waste of unknown composition constitute...

Municipal solid waste incinerator (MSWI) bottom ash is often used as the protection layer for the geomembrane and intermediate layer in the landfill. In this study, three sets of simulated landfills with different mass proportion of MSWI bottom ash layer to municipal solid waste (MSW) layer were operated. Cu and Zn concentrations in the leachates and MSW were monitored to investigate the effect...

This paper compares life-cycle greenhouse gas GHG emissions from two municipal solid waste MSW management options, municipal waste combustion, and landfilling, using a U.S. EPA life-cycle assessment LCA model, the MSW Decision Support Tool. Unlike previously reported LCAs, key combustion model inputs—total MSW carbon content and its biogenic/fossil split—are determined not from MSW composition ...

The Environment Agency is required to monitor the diversion of biodegradable municipal waste (BMW) from landfill. Reliable methods are needed to measure the biodegradability of municipal waste, both as mixed municipal waste and as individually separated fractions. An evaluation of several methods was carried out using a variety of organic materials typically found in municipal solid waste. The ...

The United States disposes roughly 60% of the municipal solid waste it generates each year in solid waste disposal facilities, commonly known as landfills. Hedonic pricing studies have estimated the external costs of landfills on neighboring housing markets, but the literature is silent on what happens to property values after the landfill closes. Original housing price data collected both befo...
