Landfilling is a less controlled process than combustion, and conditions in a landfill change
over time. Unexpected leaks and emissions are difficult to locate, and the results of efforts to
monitor emissions are therefore less precise for landfills than they are for combustion facilities.
The variation from landfill to landfill is also substantial. Sophisticated models of the reactions in
a landfill have been constructed, and the data collected in actual studies are generally consistent
with the predictions of the models. However, few studies have attempted to quantify air and
water releases from landfills over long periods of time; long-term data on ash monofills are
Data on separation and recycling, with or without curbside collection, are limited, in part
because the approach is relatively new. Successful recycling depends more strongly than the
other disposal options on nontechnical factors that have not been widely studied. For example,
few studies have been found of quantities of recyclables set out for curbside collection over a
period of several years. In addition, the success of a recycling operation depends on finding
beneficial uses for the products. Extensive data about energy requirements for remanufacturing
are available, but only incomplete and out-of-date information on environmental releases during
manufacture and remanufacture were found. The lack of systems studies that follow MSW
recyclables from curbside to a remanufacturer's product shipping dock is a significant barrier to
Here’s what’s next.
