Rice-hull bagwall construction
Rice-hull bagwall construction is a system of building, with results aesthetically similar to the use of earthbag or cob construction. Woven polypropylene bags are tightly filled with raw rice-hulls, and these are stacked up, layer upon layer, with strands of four-pronged barbed wire between. A surrounding "cage" composed of mats of welded or woven steel mesh on both sides and then stuccoed, to form building walls.
Advantages include less weight to handle/process, far better insulation values, use of an agricultural-waste product and the sequestration of CO2. This building approach was originally innovated and tested by Don Stephens, in the northwestern U.S. in 2005.
