Discarded and eventually landfilled or incinerated in landfills, it is almost the ultimate fate of most domestic sterile paper packaging. However, in the eyes of the resource recovery and recycling industry, these waste packaging is entirely a kind of "misplaced resources." As an example, Tetra Pak's aseptic paper packaging, which occupies 90% of the Chinese aseptic packaging industry's market share, consists of 6 layers consisting of 4 polyethylene plastic film layers, 1 paper fiber layer and 1 aluminum foil layer. The process can produce recycled products such as recycled paper, plastics and aluminum products.
an environmental engineer at Tetra China Ltd., the recycling technology of Tetra Pak is mainly divided into three categories: one is to shred waste packaging directly, and then heat-pressed to make a color plate for manufacturing. Trash cans and other products; one is to separate waste packaging into pulp and aluminum plastic pulp through hydraulic pulping, pulp is used to produce recycled paper products, while aluminum plastic is used to produce aluminum and plastic products; there is also a kind of waste packaging. Milling extrusion is used to produce plastic-wood products such as flooring, industrial pallets, etc.
