100% biobased particleboards based on new agricultural wastes
The agriculture in France offers exceptional wastes that can be recycled and turned into biomaterials. This paper presents a comparison between the properties of particleboards made from different agricultural wastes (hemp and flax shives, sunflower bark and rape straw) and those of classical particleboards based on wood. The use of these new agroresources as materials could increase the potential supplies for this application and could provide an additional source of income for farmers. The particleboards are made by thermocompression without synthetic binder addition. Thermal insulation, mechanical and hygroscopic properties of the panels are measured and discussed with regard to the used agricultural resources.
