A garbage compactor consists of a hopper, compaction chamber, and ram plate powered by a motor. When waste is loaded into the hopper, the ram plate compresses it, reducing its volume and increasing its density. Various types of compactors exist for residential, commercial, and industrial use, constructed with materials like steel and hydraulic fluid. For safety, they incorporate switches and sensors to prevent accidents. Optional accessories like remote controls and trash bags enhance functionality. Entities related to compactors, such as manufacturers, provide additional context.
