Many reasons to consider Plastic Piping Systems

The many positives for the use of plastic piping systems include: long service life proven in practice good recycling characteristics high chemical resistance properties simple handling negligible piping losses cost-effective A PVC-U sample pipe was installed in Hamburg in 1937.The PVC pipes were joined using bonding agents. The system was operated at 4 to 6 bar. The material was used to supply drinking water to the public and was, without exception, successful. Even after this long operational period, there was no evidence of incrustation or deposits. Analysing the individual positions of ecological balance, it can be demonstrably established that plastic piping systems are not only economical, but also technically and especially ecologically profitable when compared with other material...

How can plastics be recycled?

Although plastics make up only 6 % of oil consumption, the conclusion is that the energy value of plastic must be used. There are two possibilities of recycling: 1. reutilisation, production of new products 2. combustion, production of thermal energy In the case of reutilisation the plastic waste is brought back to its original form in different procedures (hydrolysis, pyrolysis, regranulation). At GF, production waste is regranulated and integrated into the production process of products with lower quality and hygienic requirements than that of pipes and fittings. All thermoplastics are recyclable, e. g. PE, PP, PB, PVC-U, PVC-C, ABS or PVDF. This is, however, not the case for thermosetting plastics and thermoelastomers such as PE-X. Incineration together with domestic waste (no PVDF) does not pose any problems. In this case we talk about energy recycling, as almost all incineration plants recover waste heat. Plastics as well as other materials cannot be transformed into nothing, so disposal in waste dumps is not the solution. This is why the use of recyclable and energy recyclable plastics should be promoted....
