Getting a Good Niaht's Sleep

摘要

In the world of landfills, the transition from active to closed status is much like the transition from feast to bed. When a community is done "feeding" the landfill, i.e., finished actively adding waste to it, owners pull a cover from the toe to the crown of these giants and allow the necessary digestive processes to take place. The digestive process in this analogy equates to solid waste degrading over time until the landfill can move into a "post-closure" care step and, eventually, into productively reusing the land. Often, the landfill flare-the controlled flame that burns off excess landfill gas-is the most conspicuous sign of the digestive process. Flares, in tandem with a landfill's post-closure slumber, may operate for several decades during which time owners diligently keep. watch. Some landfills sleep soundly, while others may suffer indigestion-often in the manner of excess landfill methane and other contaminants impacting landfill area groundwater, soil, and gas-and require special attention.
