One of the broad benefits that’s come out of organic farming: more and more, farmers don’t view byproducts of harvesting and processing their crops as waste. Rather, they’re often used as soil amendments or soil builders<\/a>. If they’re not used in that capacity, there may well be a market for those leftover husks and stems and fibers. Steve Hanley has discovered one such new use for rice straw, the leftover material from rice farming: a building material. Green Wood is waterproof, fungus-resistant, and mud-proof alternative to earthen blocks or wood. It also means reducing or even eliminating burning of rice straw, which contributes to CO2 emissions and particulate pollution.<\/p>\n

Steve covered this material on sister site Green Building Elements<\/a>; we’ve reposted it below. Take a look, and let us know what you think: are Green Wood and\u00a0Stak Blocks\u00a0(created in the US) sustainable materials that could revolutionize home and shelter building in the developing (or even the developed) world?<\/p>\n

Green Building With Renewable Rice Straw<\/h2>\n

\"Rice<\/a><\/p>\n

For every ton of rice that is grown, 500 lbs of rice husks and straw are created. Typically, those husks and straw are burned as waste. But two innovations on opposite sides of the world are changing that.<\/p>\n

In India,\u00a016-year-old Bisman Deu saw all those rice husks being burned and wondered whether they couldn’t be put to better use. So she started experimenting in the family kitchen and came up with a material she calls Green Wood.<\/p>\n

Her creation is a\u00a0waterproof participle board that is fungus resistant\u00a0and mud-proof, making it a good alternative to the earthen bricks used by many poor farming families around the world, especially when monsoon season arrives.\u00a0Turning the rice waste into a useful building product instead of burning it keeps carbon dioxide out of the air and augments farm income because now farmers can sell the waste rather than destroying it.<\/p>\n

Deu has been recognized by a Junior Achievement award and praise from UNICEF for her creation.<\/p>\n

\"Rice<\/a><\/p>\n

Meanwhile, in Goleta, California, a start-up company called\u00a0Oryzatech, formed by architect\u00a0 Ben Korman and \u00a0his partner Jay Ruskey, is experimenting with building blocks made from compressed rice straw and glue. Looking much like oversized Legos, their Stak Blocks<\/a> have three times the insulating power of a 2X6\u2033 studded wall and are easier to handle than straw bales, which have become popular for making sustainable buildings.<\/p>\n

A 1\u2032 by 1\u2032 by 2\u2032 long Stak Block weighs 30 pounds and can be easily maneuvered by one worker. Like straw bales, they require a concrete foundation and must be kept dry with\u00a0exterior siding. Sheetrock and paneling can be screwed to the interior surface. Korman thinks the blocks will sell for about $8.00 each once production ramps up.<\/p>\n

Both products take waste agricultural products and turn them into carbon neutral, sustainable building materials. Both can be made locally near where rice grows, reducing the energy and expense needed to haul the waste to a factory.<\/p>\n
