A hemp farm in Cambridgeshire, England, Margent Farm manufactures various household products, as well as these corrugated construction panels made with hemp fibres stabilized in a bio-resin matrix (which consists of such agricultural waste as corncobs, oat hulls and bagasse). Replacing PVC or steel, the 120-by-105-centimetre panels can be used to create eco-friendly, carbon-sequestering rainscreens.
