A baling press is a waste management machine that compresses recyclable materials including paper, cardboard, and plastic into compact, manageable bundles (bales). A baling press, also known as a baler or baling machine, is a big steel chamber with an up-and-down pressing plate that presses the material inside. Waste collection firms collect the thick, compressed bales created by the press, which are then sent to recycling organisations for resale and reuse. A baling press is primarily used to compress recyclable materials such as paper and cardboard, plastic, polystyrene, cans and drums, metal, and glass, though it can also be used to compress unusual items like automobile bumpers or clothing.
