Waste compaction is the process of compacting
Consumer and post-collection compaction
Pre-landfill waste compaction is often beneficial, both for people disposing of waste and the company collecting it. This is because
Landfill compaction
A landfill compaction vehicle has two main functions: to spread the waste evenly in layers over the landfill, and to compact waste to reduce its volume and help stabilize the landfill. Proper waste compacting includes the process of using a steel wheeled/drum landfill compactor to shred, tear and press together various items in the waste stream so they consume a minimal volume of landfill airspace. The higher the compaction rate, the more trash the landfill can receive and store. This will also reduce landslides, cave-ins and minimize the risk of explosions of landfill gas (see landfill gas migration).
Main compaction is produced by the landfill compactors steel tooth on the wheel drums. Special teeth can penetrate the waste and deliver a focused compression point, providing compaction and increased density. Ground pressure of the tooth can exceed over 4,000 pounds per square inch (28,000 kPa) (
Advantages and disadvantages
Loose, non-compacted trash occupies up to 20 times more dumpster space than compacted waste. Waste haulage costs are reduced by fewer or smaller dumpsters, and dumpster pickup frequency can be reduced by 50 percent. A side effect of waste compaction is that important items, like evidence in a crime, may be difficult to recover from the garbage. Due to reduced
