Exploitation of plastic waste is current issue in part of recycling in this present. Current recycling appears possibility of manufacturing of composite materials WPC (woodplastic composite). While a few decades ago as a plastic matrix used thermosets, currently often is using thermoplastics. The reason among other things is also able recycling these composite materials. The most common example exploitation of plastics is currently PVC, PE and PP. Application of construction thermoplastics (PA, POM, PET) is limited with increased processing temperature, at which there is a degradation of lignin in the wood. The problem of exploitation of thermoplasts in comparison with thermosets is high viscosity of thermoplastic melt and decrease of wettability whit wood sawdust. For this reason is increasing of attention for determine of maximum quantity of filler wooden components.
