A new technology that turns agricultural waste into a building material has the promise of solving problems of carbon emissions and building affordable housing, including earthquake-proof construction in China.
The Alberta Research Council in Edmonton has discovered and developed a technology that uses wheat straw, which is the byproduct of harvesting wheat, to create a plywood-like material that is durable and affordable. The new material is called Oriented Split Straw Board (OSSB). The new material is made by compressing the strew together with resin. There is a plant in Yangling, in Shaanxi province, that has already begun to produce the new material. It is able to produce over 5,000 panels a day, enough building material to build 30 houses.
The new technology is extremely promising for China because they do not possess enough trees for large-scale lumber production, but the country does possess lots of wheat straw. Not to mention, China expects that the population will need 200 million new houses over the next twenty years. OSSB is a great discovery because it can help preserve the world’s forests.
The new material is also more flexible than traditional wood, which should prevent buildings from completely collapsing during earthquakes. The material seems great because it will lead to less carbon emissions because at this point, farmers burn the wheat straw to clear their fields. Also, traditional bricks require the land to be mined and eroded to collect the clay. Using OSSB panels will create less of a demand for clay bricks. All around, this new Canadian technology seems to have little downside and unlimited potential for the world’s home builders.
