Title:
DEVICE FOR TREATING PLASTIC
Document Type and Number:
WIPO Patent Application WO/2011/059095
Kind Code:
A1
Abstract:
Provided is a device for treating a plastic by which, from a plastic waste comprising a cellulose ester as the main component, not only carbon but also other components can be adequately collected and treated to give useful materials that can be effectively utilized for various purposes. The cellulose ester constituting the plastic is hydrolyzed in a hydrolysis unit (10) and the individual components thus hydrolyzed are separated in a separation unit (11) to give solid matters containing cellulose and a solution of an acid component having been bonded to cellulose via an ester bond. The solid matters and solution are each reusable or can be used in producing other materials. Namely, the solid matters containing cellulose can be converted into other products and utilized as, for example, activated carbon, fuels, packing materials and so on, while the solution of the acid component having been bonded to cellulose via an ester bond can be directly reused as a starting material of plastics and other products. Thus, the useful components contained in the plastic waste can be economically utilized and the amount of the waste can be reduced, thereby reducing impact on the environment.
