Pallmann recycling solutions re-use PVC left-overs the smart way

A €1.2 million investment in an upgraded recycling facility to re-use PVC production left-overs is now being applied by Protan Group, the Norway-based manufacturer of roofing foils and ventilation tubes for tunnels and mines. German size-reduction technology specialist Pallmann provided the cost savings recycling solution.  .

Protan is now running a state-of-the-art, tailor-made three-in-one recycling installation for grinding, agglomerating and pulverising. The company, which has an annual turnover of one billion Norwegian Crowns (€110 million), is one of the world’s largest manufacturers and suppliers of innovative roofs, membranes, technical textiles and ventilation systems. Hundreds of kilometers of its ventilation pipes are installed every year in mines and tunnels around the globe - mainly in Europe, Africa and South America.

Protan wins most of its work - some 65% - from above-ground applications, such as the fabrication of foils for roofs on office and industrial buildings located in some of the most challenging climates in the world. Over the past 40 years, Protan’s coverings have been installed on roofs in conditions as diverse as the African desert and the tundra on the Spitzbergen archipelago in the Arctic Ocean.

It is in its roofing products that Protan uses most of its recycled materials. On average, it incorporates 6% recyclate in its production process, most of which is sourced in-house. Owing to their complexity, it is difficult to dispose of or use these materials in other applications; however, the materials are of high value, making internal reuse worthwhile.

Protan started recycling two decades ago and Pallmann’s engineers have been involved from the earliest pioneering stage. The size-reduction technology major installed a reconditioned PFV agglomerator in Protan’s plant in 2000. Over the years, this solution has become outdated that the company opted for an upgrade.

In the new facility, grinding is undertaken by Pallmann’s knife mill-type PS 4-7,5; agglomeration is carried out in a Plast agglomerator PFV 250; and a PolyGrinder PM 300 unit takes care of the pulverising. The machines are connected via conveying units, silos and collection units. Pallmann supplied and commissioned the entire package of components.
