Recycling of plastics

Since about 1990 plastics recycling has been a growing and developing business. It is here to stay in one form or another. Collection and separation are the main problems. PET and HDPE by far are the main plastics that are most easily recycled. These two polymers are used as containers and easily reprocessed. Plastic films (especially LDPE) have a potential for recycling increases, but this form of plastic material is not as easily collected and stored. [Pg.301]

X-rays can easily determine the presence of PVC via the chlorine atom. Single wavelength infrared is used to separate clear (PET and PVC), translucent (HDPE and PP), and opaque (all pigmented materials and colored HDPE) streams. Full-spectrum infrared can detect differences in [Pg.302]

Total recycled thermoplastic resin production almost tripled between 1990 and 1995 and is well over 1 billion lb per year. The percentage breakdown of the amount for recycling is the following HDPE (especially bottles), 35% PET (soft drink bottles), 34% PP (auto battery cases), 14% LDPE (film), 9% PS (packaging), 3% PVC, 0.5% other, 4%.

On land, too, there are changes in the way plastics are disposed of. In the UK some local authorities are actively promoting recycling of plastic bottles and poly(styrene) containers, for example by schemes where local residents place recyclable materials in designated boxes for refuse collectors. These boxes are taken to a Materials Reclamation Facility for final sorting of the plastics waste. [Pg.169]

Finally, other relevant treatment options for plastics waste include landfill and mechanical recycling. Since these options (unlike Vinyloop and cement kiln incineration) are not even similar to feedstock recycling we discuss them here only very briefly. Mechanical recycling of plastics (be it PVC or other plastics), needs dedicated collection of the plastic waste in question. This is only possible for selected plastic flows (high volumes, recognisable products, products consisting mainly of one plastic). Landfill can accept plastic waste in any waste context (pure plastic type, MPW, mixed materials). I will only address the costs of these alternative technologies. [Pg.22]

The recycling of plastic materials becomes more and more important, but unfortunately it is not possible to make materials from the same quality as that of the virgin material. For PVC, this problem is even more pronounced than for other plastics. A process is studied which is able to destroy the waste PVC, but which can recover the most important component of it - chlorine - as a raw product for VCM manufacture, with a very high yield. Most of the energy contained in the PVC can be recovered as electrical power and steam. 4 refs. [Pg.73]

The recycling of plastics waste is eonsidered with respect to energy recovery through incineration. It is claimed that burning solid municipal waste could produce nearly 10% of Europe s domestic electricity and heat and conserve resources by replacing, for example, over half of current coal imports to Western Europe. The potential for power from waste plastics and examples of energy from waste in action are described. [Pg.74]

This article discusses the recycling of plastics back into raw materials, and looks at the recycling activities of several companies across Europe. [Pg.76]

Details are given of a pilot plant for the chemical recycling of plastics which has been established at Grangemouth, Scotland, by a consortium consisting of BP Chemicals, DSM, Elf Atochem, EniChem and Petrofina. The plant, capable of treating 300 tonnes of waste yearly, uses a low pressure, fluidised bed thermal cracking process. [Pg.80]
