Cardboard recycling is the process of collecting and processing used cardboard materials to create new products. This helps reduce waste in landfills and conserves natural resources. Cardboard is made from trees, so recycling it also saves trees and energy needed for production. The recycling process typically involves collecting, sorting, and shredding the cardboard. After shredding, the material is mixed with water and chemicals to break it down into pulp. This pulp is then cleaned and dried to form new sheets of cardboard, which can be used for packaging, boxes, and other products, promoting a sustainable cycle.
