Long-term estimates make clear that the amount of solid waste to be processed at landfills in the Netherlands will sharply decline in coming years. Major reasons can be found in the availability of improved technologies for waste recycling and government regulations aiming at waste reduction. Consequently, market size for companies operating landfills shrinks. Among the companies facing the pro...

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...

The U.S. per-capita figure for garbage production has topped four pounds per person per day, and that amount is rising at roughly 5% per year. In the past, municipal solid waste was sent to the nearest local landfill or incinerator. But in 1988, the U.S. Environmental Protection Agency instituted the first federal standards for landfills, designed to make them safer. Over 10,000 small municipal...

Methane gas is a by-product of landfilling municipal solid wastes (MSW). Most of the global MSW is dumped in non-regulated landfills and the generated methane is emitted to the atmosphere. Some of the modern regulated landfills attempt to capture and utilize landfill biogas, a renewable energy source, to generate electricity or heat. As of 2001, there were about one thousand landfills collectin...

The Danish counties have performed numerous investigations of old landfills. These investigations have been presented in several reports, but no comprehensive summary of the findings has been carried out. The objective of this study was to evaluate the typical composition of leachates from old smaller landfills by a comprehensive review of the investigations carried out by the counties. In tota...

Major environmental concerns of municipal landfills revolve around quantity and quality of leachate, gas generation, and decomposition processes occurring therein. Minimizing the time period for maximum biodegradation to reduce leachate and gas emissions after landfill closure, ease the requirement of leachate treatment, and reclamation of landfill site is the most sought after managers proposi...

Adsorbable organic halides (AOX) and AOX formation potential (AOXFP) were investigated in 46 landfill lea-chates as potentially toxic parameters. AOX in landfill leachate was within the range <10–2200 mg Cl/l, and AOXFP was within 51–15 000 mg Cl/l. AOX and AOXFP correlated with chemical oxygen demand (COD).AOX discharge from closed landfills was generally lower than that from operating landfil...

The management of rapidly growing municipal solid waste (MSW) is one of the major challenges in developing countries. The current study also estimates the suitability of a site through a geographical information system using multi-criteria decision analysis (MCDA) for landfill sites in National Capital Territory (NCT). The results of the suitability index indicate that only 58.7 km2 of the land...

Wood pallet recovery, repair, and recycling are sound environmental activities that can reduce both forest resource demands and waste in landfills. Our studies found that 6.16 million tons of wood pallets (or 223.6 million pallets) entered municipal solid waste (MSW) and construction and demolition (C&D) landfill facilities in 1995. At the same time, wood pallet recovery, repair, and recycling ...

The annual production of municipal solid wastes (MSW) in Russia, Finland and Ireland in the late 1990s accounts for 37.5, 2.5 and 2.05 min. tonnes or 252, 488 and 566 kg per capita, respectively. 96.5, 64 and 91% of these wastes (for Russia, Finland and Ireland, correspondingly) are currently disposed of via landfilling. However, nowadays, MSW management in these countries is undergoing drastic...
