he United States is running out of T landftlls and that is where most trash, and thus most packaging 1 material, ends up. For example, we generate 180 million tons of solid waste per year, 70% of which goes into landfills. However, in the last 12 years, two-thirds of our landfills have been exhausted. The problem gained national attention in 1989 when a garbage barge from New York wandered acro...

One scenario for long-term nitrogen management in landfills is ex situ nitrification followed by denitrification in the landfill. The objective of this research was to measure the denitrification potential of actively decomposing and well decomposed refuse. A series of 10-l reactors that were actively producing methane were fed 400 mg NO3-N /l every 48 h for periods of 19-59 days. Up to 29 nitr...

Abstract The aim of the present research was to develop a mathematical model for estimating amount viscous gas generated as function weather conditions. Due lack models predicting formation caused by sudden changes in conditions literature, such developed this study using parameters landfills recorded over year. effect temperature on landfill production has proved be particular interest. We con...

The goal of this analysis was to explore a GIS-based technique to assess the potentially suitable locations for monitoring air toxics pollutants emitted at landfills. Several map layers such as landfill activity, population density, and distances from other emission sources were incorporated into three different suitability modeling scenarios. The ArcGIS Spatial Analyst tool was used to perform...

M icbial Trsform aion of O rgnotin C om punds uder im uated Ldfill C onitions Liöping 2007 The cycling of tin is a topic of concern because of its anthropogenic entry of organotin compounds into the environment. Special attention is given to the transformation of organotins and the methylation of inorganic tin, since these processes often give rise to more toxic formulations. By far the largest...

This study compared the environmental impacts of composting yard wastes in windrows with using them in place of soil as alternative daily cover (ADC) in landfills. The Life Cycle Assessment was made using the SimaPro LCA software and showed that the ADC scenario is more beneficial for the environment than windrow composting. ADC use is also a less costly means of disposal of yard wastes. This f...

We examine the problem of the intertemporal allocation of the solid waste of cities within the United States to spatially distributed landfills and incinerators, taking into account that capacity at existing and potential landfills is scarce. Amendments to the Solid Waste Disposal Act have been proposed to restrict waste flows between states by means of quotas and surcharges. We assess the aggr...
