Wood-plastic composites – replacing plastics with wood
In the quest for new alternatives for crude oil based materials such as plastics, WPCs (Wood-plastic composites) seem to be suitable materials, used in buildings and in the automobiles production. WPC are natural fiber composites with properties of both plastic and wood. It is estimated that the production of WPCs will experience an annual growth of 14% between 2014 and 2019 according to a study by the University of Eastern Finland.
In the study a new sort of additives to the WPC were investigated and the VOC release monitored with IONICON PTR-TOFMS.
Putting waste to use – liquids separated from wood as additives in WPCs
Liquid by-products generated from biochar production and heat treatment of wood were observed to enhance the compatibility of wood and plastic as well as to improve water absorbing and weather resistance properties of the material in the study. Moreover, these additives are process waste and can be re-used for the WPC production.
