Which description correctly identifies stationary compactors?

Which description correctly identifies stationary compactors?

• A. Stationary compactors contain a ram that pushes and compresses waste into a container or bale.
• B. Compactor collection trucks use a hydraulic ram to push waste into the truck body.
• C. Landfill compactors have a blade and steel wheels.
• D. Shredders reduce waste volume by tearing material.

Answer: (A)

Stationary compactors are fixed waste-collection units that use a hydraulic ram to push and compress waste inside a metal container or into a bale. This design stays in one location and produces a dense, manageable form of waste that can be hauled away when full, reducing the number of pickups and handling work. The description matches because the defining feature is that ram pushing waste into a container or bale, which is exactly how these units operate in a stationary setup. Other options describe different equipment. A compactor on a collection truck compresses waste inside the truck body and is mobile, not stationary. Landfill compactors are large, mobile machines used at disposal sites and typically involve heavy rollers or other compacting methods, not a fixed ram into a separate container. Shredders reduce waste volume by tearing material rather than compacting it into a container or bale.
