Packaging waste plastics composition

The composition of feed polymers also has an important effect on the properties of products. In the experimental work of Miskolczi et al. commercial waste plastics from the packaging, electronic and automotive industry and the agriculture were used as raw materials. The samples contained high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), ethylene-propylene copolymer (EPC), polystyrene (PS), polyamide 6.6 (PA 6.6) and polyvinyl chloride (PVC). 

A real plastic waste collected by the German Dual System (DSD) from municipal packaging waste was pyrolyzed in the laboratory plant as well as in the pilot plant. The composition of the mixed plastic wastes is shown in Table 17.4. 

Air and water pollution are sufficiently managed according to the law and ordinance, as in other liquefaction processes. In addition, this process can be applied to treat waste plastics from households, from industry and from agriculture, since the composition of plastic containers and packaging is well known (i.e. they contain PVC, PVDC, and ABS, and sometimes thermosetting plastics). 

The most satisfactory strategy for successful recycling of engineering polymers to durable end products is to use only one source of plastic waste whose composition and history are known. This then permits the design of a stabiliser system which will S5mergise effectively with what remains of the previous stabiliser package or, at worst, will not antagonise with it. 

Recently, wool waste has been employed as reinforcement in polymer composites, even though wool waste fiber plastic composites represent a relatively small industry. The properties of wool waste reinforced PLA/BR blend composites can be improved by chemical treatment for packaging application. 

Packaging materials. The composition and preparation of the material used to package the material to be decontaminated can interfere with the process. Waste sealed in plastic bags, for example, is almost impossible to decontaminate. In fact, even the so-called autoclavable plastic bags do not always allow for penetration of the steam to the interior.
