Waste post-consumer

Coalition ofJSlortheast Governors. The CONEG model heavy-metal guideline is implemented through state regulations and limits total metal content of lead, chromium, mercury, and cadmium. The limitation of 100 parts per million total is aimed at protecting the environment from the disposal of post-consumer waste. 

New plant constmction will bring iacreased capacity to a level which will depend on real growth to keep sales abreast with production. It is anticipated that consoHdation of ownership will continue and that the trend to specialized busiaesses supporting a plant faciUty will also continue. Pressures from environmental issues could change the cost of final products as well as mandate the use of post-consumer waste resia as feedstock for production. 

Lewis acids, such as the haUde salts of the alkaline-earth metals, Cu(I), Cu(II), 2inc, Fe(III), aluminum, etc, are effective catalysts for this reaction (63). The ammonolysis of polyamides obtained from post-consumer waste has been used to cleave the polymer chain as the first step in a recycle process in which mixtures of nylon-6,6 and nylon-6 can be reconverted to diamine (64). The advantage of this approach Hes in the fact that both the adipamide [628-94-4] and 6-aminohexanoamide can be converted to hexarnethylenediarnine via their respective nitriles in a conventional two-step process in the presence of the diamine formed in the original ammonolysis reaction, thus avoiding a difficult and cosdy separation process. In addition, the mixture of nylon-6,6 and nylon-6 appears to react faster than does either polyamide alone.

Post-industrial waste and sorted post-consumer wastes (PCW) are suitable raw materials. However, they contain different amounts of inhomogeneities formed during the service life and non-polymeric impurities. These contaminants account for differences in mechanical properties and ageing resistance between recyclates and the respective virgin plastics. Recycled plastics are often used in low-grade applications, and it is generally believed that the mechanical performance of recyclates is lower than that of virgin materials.

The first target in Europe is to recycle at least 25% of the collectable available quantity of PVC flooring waste by 2006. Applications for recycled material and cooperation in the collection and future processing of post consumer waste are ongoing, primarily based on material generated via the VinyLoop process (www.vinyl2010.org). 

According to the European Council of Vinyl Manufacturers, the PVC industry in Europe is hoping to achieve a recycling rate of 10 to 15% for post-consumer waste by 2010. This would require the recycling of an additional 350,000 to 600,000 tonnes of PVC. A run-down of recycling technologies in the latest report of Vinyl 2010 indicates that the industry has much to do to meet this target. EUROPEAN COUNCIL OF VINYL MANUFACTURERS...

Although direct liquefaction of waste plastic looked promising, problems associated with impurities (paper, aluminum, etc.) and chlorine derived from PVC caused operational difficulties. Consequently, it currently appears that the first step of any feedstock recycling process for waste plastics or tires should be pyrolysis, which allows much easier separation of solid impurities and chlorine. Research on pyrolysis of post-consumer plastic has been carried out by Kaminsky and co-workers [17, 18], Conrad Industries [19, 20], and Shah et al. [21]. Shah et al. [21] conducted pyrolysis experiments on relatively dirty post-consumer waste plastic obtained from the DSD. The pyrolysis oils were then subjected to hydroprocessing to convert them into high-quality transportation fuels (gasoline, kerosene, diesel). 

Plastic wastes may be the remains of production or post-consumer wastes, the latter being classified as municipal, packaging, agricultural, automotive and electrical. Packaging wastes are the major category [33, 52-54]. These are mainly thermoplastics such as polyethylene, polypropylene, polystyrene and polyvinyl chloride [28, 33, 55-56]. 

In some cases, the advantage of a sustainable product is specific and readily observable by the customer, such as a Post-it Recycled Paper Notes, made with 100 percent recycled paper fiber (20 percent post-consumer waste). 3M paint replacement films, which allow automobile and aircraft manufacturers to reduce their use of paints and solvents, are an example of an industrial application where the customer is striving to achieve its own sustainability goals.

These use post-industrial waste (PIW) and some post-consumer waste (PCW) in their middle plies. They can be faced with better quality facing materials and may or may not have a quality backing used for low-grade small boxes and cartons.

The most difficult is the post-consumer waste, PCW, e.g., from households, consisting of a variety of composition, viz. PO, PVC, PS, polycondensates (viz. PA, PC, PET), etc. As shown in Table 16.1, composition of PCW varies from one country to another. The plastics that belong to this category, first must be separated then cleaned. Alternatively, they may be processed, e.g., into a variety of plastics woods..
