Wood Plastic Systems - Natural Wood in Drinking Water Plastic

WOPAS is the new alternative for utility poles and marine piles. After carefully having listened to grid owners, line men and marine constructors, and after five years of research and development, WOPAS launched its innovative concept to the market in 2017. 

WOPAS utility pole and marine piles offers generates less environmental footprint and a much improved working environment based on an innovative technology with proven materials - natural wood in drinking water plastic. Finally!

Energy & Telecom  - WOPAS value proposition 

Natural wood - free from toxic impregnatation - encapsulated with drinking water plastic - compatible with climbing shoes and fastening material - unprecedented mechanical properties - wood pecker resistant - 60-80 years life time - fully recyclade to new products - YES PLEASE!

WOPAS value proposition

Design for Recycling

As an integrated part of the research and development, WOPAS involved Stena Recycling to understand the whole life cycle of the materials. The WOPAS wooden structures remain uncontaminated and represents no hazardous materail, but can instead be reused into new products. In other words, not special waste triggering long distance transport and cost for destruction. Smart!
