Recycling Polymers

The development of the synthetic polymer industry has been related more to the economic advantages that the materials bring rather than their environmental benefit, yet these economic considerations have led to plastics making a significant beneficial impact on the environment. For example [Pg.441]

The economic arguments in favour of plastics, rather than their environmental benefits, have generally prevailed and have led to the dramatic growth in the industry. These same economic arguments in terms of the low cost of production have mitigated against recycling and have spawned [Pg.441]

Furthermore, the relative chemical stability of the plastics commonly used in packaging means that there is no significant degradation in landfill sites. This is an advantage in terms of the stability of the landfill site, but has contributed to the need to find more new sites. The growth of the NIMBY ( Not In My Back Yard ) lobby has brought political pressure to control the development of new landfill sites, and so the disposal of MSW [Pg.442]

The need for integrated waste management systems that take account of both the financial and non-monetary aspects has been recognised [6], and the chemistry of recycling synthetic polymers is of fundamental importance in an understanding of the role that the available technologies can play in such integrated systems. [Pg.443]

Whilst pol3miers do pose a waste disposal problem they also afford many environmental advantages when compared with the alternatives. These advantages are often connected with their low weight-high strength properties. Replacement of 250 kg of metal in a car by an advanced polymeric material can save 7501 of fuel over the lifespan of a car [Pg.49]

Polymer recycling process costs for various operations are summarized in Table 6. [Pg.233]

Most ester-forming reactions are reversible. Depending on circumstances, these reactions may be either undesirable side reactions, for example hydrolytic chain scissions occurring during processing, or useful reactions when chemical modification or polymer recycling is considered. [Pg.39]
