Recycling of Aseptic Beverage Cartons: A Review

Aseptic beverage cartons are multilayer polymer-coated paperboards with a layer of aluminum foil. Due to their structure it is commonly assumed that they cannot be recycled. This not the case and this review details multifarious processes used recycle aseptic cartons. Hydrapulping recover paper fibers constitute 75% carton most widespread process, followed by manufacture construction materials such as boards tiles which utilize complete carton. A range mechanical, chemical thermal separate PolyAl (polyethylene aluminum) residual remains after have been recovered. The simplest process involves agglutination extrusion obtain pellets can then in industrial consumer products or combined other lignocellulosic wastes. Chemical approaches involve solubilization polyethylene removal aluminum. Various also investigated novel microwave-induced pyrolysis appears commercially viable. It concluded focus future years likely on recycling into where there theoretical yield 100% compared for hydrapulping.
