Research and Markets Offers PVC and Mixed Plastics Recycling Information

The book, which is comprised of 11 chapters, was compiled from contributions from an array of scientists from several countries who are playing a leading role in plastic recycling, according to Research and Markets.

The book’s first two chapters cover thermal stabilization of PVC that is to be recycled. Several practical and effective ways of recycling PVC are proposed, according to the company. Data show that a well-designed system can reduce stabilization costs.

The next two chapters deal with successful commercial operations. In one, fully automated operation developed by VEKA in Germany, complete PVC windows containing PVC, glass, metal and rubber are recycled. No dismantling of the window is needed. Another process, developed by Solvay in Belgium, recycles PVC bottles and pipes. The properties of products made from this recycled material are equal those of the original polymers, according to the book.

Several chapters are devoted to the technology of processing mixed plastic scrap. The text emphasizes degradation, morphological structure, molecular weight and branching of component polymers and the effects of these factors on the performance of blends of recycled polymers. Several methods of compatibilization are covered, including selection of compatibilizers and cost-effective methods of production. A form of mechanical dispersion is proposed as an alternative to chemical compatibilization, as well.

The final two chapters review the effect of contamination and UV stability of recycled polymers. The effect of contaminants and methods of their removal are discussed.
