Typha as a circular building material.

Abstract Innovation towards biobased energy concepts. In 2050, the European Union aims to have created a carbon free and circular society. At same time nature biodiversity needs be restored. For current transition in built environment this means not only developing solutions that can reduce consumption considerably, preferably changing environment, who currently is responsible for 40% of total worldwide, into an producing part This also embodied environmental impact used major renovation challenge lowered substantially, or better still, transformed positive impact. The aim paper describe outcomes development sandwich panel from Typha. Research make inventory possibilities realizing roof element with use Cattail (Typha) as construction insulation material. It important determine what properties are new sheet material preconditions needed construction. Currently industry mainly uses harmful binders, such aldehydes isocyanates, these chemicals heavily polluted These binders cannot regarded solution therefore alternatives had found. How made which adhesives important? Finally, it Cattails contributes reduction amount nitrogen. possible concept realized negative footprint.
