Green Technology

The Serbco SA PPr pipe system has a small Carbon footprint and is fully recyclable, with a Minimum service life of over 50 years.

When comparing PPr to other systems such as PEX and Multilayer products, PPr is the hands down winner.

– PEX cannot be recycled at the moment as the regrind does not thermoplasticise. It must therefore be pulverised and used as a filler in Polyethylene products.

– Multilayer products are tainted firstly, because metal is involved, specifically Aluminium, that requires a huge quantity of energy to smelt and process. Secondly, the bonding method of multilayer pipes prevents recycling, as delamination of the product to recycle is not cost effective.

This means that once PEX and Multilayer products have reached their maximum lifespan, they will be landfilled and not recycled as PPr can. The regrinding of PPr is a very simple process and the product can be used for various second stage goods such as food packaging, carrier bags and all manner of other consumer goods. Many manufacturers claim superiority with Green Technology however, one must be careful to accept everything at face value.

With the new SANS 10400 XA and XB regulations, that have been brought into effect, many designers have been struggling with the calculation and rationalisation of the stated minimum R-value of 1. With Serbco SA PPr pipes, one can decrease the thickness of the insulation that one would have used with a typical copper installation. 25mm thick insulation is the minimum standard for a 15mm copper pipe compared to 9mm on our 20d PN16 which will give a R-value of 3.22 (Please see R-value Calculator). As such, it is evident that Serbco SA PPr will add to savings on installation prices, as well as help reduce energy costs.
