This is Metem, a material distributed by Minnesota-based Intectural, a sister company of Epicurean Cutting Surfaces and Loll Designs. Metem is made with old milk jugs — like Loll’s Rapson Collection — or to be more specific, post-consumer recycled high density polyethylene (HDPE). It’s highly durable and requires no maintenance, according to Intectural, and can used inside or out in wet or dry applications.
When I mentioned a project by students aiming to build the greenest house in Canada (by means of the Living Building Challenge and LEED Platinum certification), I noted that students planned to use “prefabricated straw bale walls.” It turns out they finished this portion of the project using BioSIPs from NatureBuilt Wall Systems in Ontario, Canada.
Push Design made news with a beautiful Hemp House in Asheville, North Carolina. It received significant media attention — notwithstanding a multitude of jokes conflating industrial hemp and marijuana. Now, hemp is being used for more projects, as shown in the above video from CBS Minnesota. Due to strict regulations, hemp is imported and mixed with water and lime to create a light, insulating, concrete-like mass for walls.
