5. Conclusions
In a wider context, our WPC research portfolio classified current WPC research predominately being in the state of incremental basic material research. WPC actually represents a successor technology for outdoor applications in the building and gardening industry. In addition, applied research with focus on products is still in its infancy and so far solely based on decking. As this material technology is not sufficiently diversifiable, the development of further applications in the building scope obviously seems to be limited which hinders the identification of potential further mass products. A positive signal is sent out by research in green-composites. The substitution of the petrochemical polymer matrix already spreads out in the state of generic basic research. Not yet acting as successor technology, this field shows a promising potential to become further developed by incremental basic research which will advance towards Quadrant II in our research portfolio. We interpret this as one step behind a possible combination with current WPC and which speaks for a spread of potential future applications.
