Product Yield from the Feedstock Recycling of Single Plastics... [Pg.288]

OIUWAX COMPOSITION FROM THE FEEDSTOCK RECYCLING OF SINGLE PLASTICS... [Pg.295]

Suitable waste plastics feedstocks are single contaminated polymers with high selectivity to monomers or commingled waste plastics. Some mixed polymer waste streams and their estimated volume, (US 1993 statistics), amenable to recovery/recycling by thermolytic processes are shown in Table [1]. [Pg.408]

Because recycled plastics have had a first use and have been environmentally exposed, required conversion processes are often more stringent. For example, compounding may have to be done on a twin rather than a single-screw extruder for dispersive mixing. In addition, compounding purification steps such as devolatilization and melt filtration may be required for some recycled feedstock. Consequently, the compounding process can have a significant impact on the overall conversion cost. Another contributor to conversion cost is the compatibilizer additive. The most effective of these additives cost about 2.00 per pound. This adds 10 cents per pound of product at a 5% level of compatibilizer additive. [Pg.145]
