6 Landfill Waste Compaction Strategies

6 Landfill Waste Compaction Strategies

This is an extreme method of compacting refuse and waste fill. This technique involves dropping heavy waste of 15-20 tons onto the surface of the fill from a height of 30 to 60 feet on a grid pattern whose spacing is determined by the weight being dropped and the nature of the waste. Dynamic compaction isn’t just used to minimize airspace.

Multiple outfall deposition (spigots) is the most common method used to fill a surface storage facility. For conventional storage facilities, multiple spigots help to control the geometry and location of the supernatant pond within the facility. This helps to prevent the pond encroaching the embankment and reduces the risk of loss of freeboard.
