A trash compactor is a device used to reduce the volume of waste materials. It works by compressing trash into a smaller size, making it easier to store and transport. This is especially useful in homes, businesses, and industrial settings where large amounts of waste are generated. Typically, a trash compactor features a container for waste and a mechanism that applies pressure to compact the materials. Some models are designed for residential use, while others are built for commercial applications. By minimizing the space needed for trash, compactors help improve waste management efficiency and reduce disposal costs.
