New in-house PVC recycling facilities at Primo Germany

Post Time:Oct 10,2018Classify:Industry NewsView:837

Primo’s production facility in Berlin produces a variety of profiles for windows and doors – in fact, the window and door profile production accounts for the majority of the production capacity in Berlin. 

With the increased focus on circular economy and on sustainability in the industry, Primo has increased the share of recycled plastics used in the window profile production. 

At the moment, some 20 % of all the PVC used in Primo come from recycled PVC, some of which is sourced internally and the rest purchased from dealers in plastic scrap. As a result of Primo’s efforts to keep production costs low and the sustainability profile high, Primo Germany has recently invested in its own mixing silo for reused PVC, all of which is intended for use in the production of profiles. 

The right time to invest in recycling

Harald Möllenkamp is operations manager at Primo’s Berlin facility and in charge of the new recycling initiative. “We have always used recycled PVC for production in some of our profiles. But it’s been difficult for us to control the quality sufficiently, and we have also experienced a jump in the price level of recycled PVC bought from dealers. So, we felt the time was right to invest in our own recycling equipment – after all, we are not just experts in extrusion, we are also quite strong when it comes to PVC compounding here at Primo.”

In the new mixing silo, cutoffs from Primo’s own profile production are mixed with PVC scrap bought from dealers. This allows Primo to create a perfectly homogeneous PVC raw material for further refinement and production.

The mixed PVC is extruded into pellets measuring 3 X 3 mm, which is ideal for production of extruded profiles and which leads to very little waste in the production process itself. In fact, the percentage of production waste has been reduced by almost 30%, which is very good value for the industry – and all waste is then recycled once again to create new PVC granulate.

“Today, up to 60 % of all our windows and door profiles are based on a core of recycled PVC, and we expect this number to increase significantly in the future,” says Harald Möllenkamp.
