There is considerable interest today in the so-called “biocell” approach toward municipal solid waste (MSW) landfilling in which leachate is introduced back into the landfill. This approach reduces the cost of leachate management and is said to reduce/eliminate the potential for long term landfill gas production and groundwater pollution. However, a critical review of the typical approach being...

OBJECTIVE To investigate the risk of congenital anomalies in relation to an index of geographic density of landfill sites across 5x5 km grid squares in England. METHODS 2 km zones were constructed in a geographical information system around 8804 landfill sites, including 607 that handled special (hazardous) wastes, and intersected with postcode coordinates of over 10 million births (136,821 w...

Post-consumer waste is a small contributor to global greenhouse gas (GHG) emissions (<5%) with total emissions of approximately 1300 MtCO 2-eq in 2005. The largest source is landfill methane (CH 4), followed by wastewater CH 4 and nitrous oxide (N 2 O); in addition, minor emissions of carbon dioxide (CO 2) result from incineration of waste containing fossil carbon (C) (plastics; synthetic texti...

Many countries are at a crucial junction on the way to tackling the ever-increasing waste problem. A fresh look at their strategic options suggests that processes such as waste-to-energy (WTE) could play a more important role. This neglected energy source could also have a major impact on power generation at a local level. It would resolve some of the potential future electricity generation pro...

Landfill leachates are not geographically specific; rarely acknowledge the impact of site specific parameters such as age, water balance, type of waste, landfill operation, etc.; and cover such large ranges that they are often of little use. Analysis of data from lined landfills in Bhopal was needed to provide useful information for the design and management of landfill leachates. Analyses were...

Degradabilities of four kinds of commercial biodegradable plastics (BPs), polyhydroxybutyrate and hydroxyvalerate (PHBV) plastic, polycaprolactone plastic (PCL), blend of starch and polyvinyl alcohol (SPVA) plastic and cellulose acetate (CA) plastic were investigated in waste landfill model reactors that were operated as anaerobically and aerobically. The application of forced aeration to the l...

Site selection of new landfills for municipal solid waste (MSW) disposal is a great concern of urban governments around the world as old landfill sites are being filled-up and demand for new sites is increasing. Finding a suitable MSW disposal site of adequate size meeting all the regulations is a costly endeavor. With the advent of geographic information systems (GIS) and its decision support ...

Relandfill activity, which means digging up landfill waste and recovering resources, can remove the material having been landfilled, and will free up the land to be reused as new landfill space. We have extended the WIO model for environmental assessment including re-landfill activity. As a part of this work, we have estimated landfill consumption and CO2 emission based on 4 kinds of scenarios ...

This study evaluates the environmental performance and discounted costs of the incineration and landfilling of municipal solid waste that is ready for the final disposal while accounting for existing waste diversion initiatives, using the life cycle assessment (LCA) methodology. Parameters such as changing waste generation quantities, diversion rates and waste composition were also considered. ...
