Oryzatech’s STAK BLOCK  is a simple building solution for a sophisticated housing problem. The company has created a hybrid composite building block from the largest bio-waste crop in the world, rice straw. Through a scalable, low energy-production process, the company can make and sell an almost unlimited supply of highly insulating, carbon-sequestering construction blocks.

Context: Common structural materials like wood, steel and concrete require huge amounts of energy  to manufacture and distribute, while all the common insulating materials are themselves oil based products.  Oryzatech’s STAK BLOCK will be the first truly resource-efficient structural/insulating wall system available for builders.  The blocks  will by definition be manufactured where food is grown, utilizing the annually renewable supply of waste straw that is currently  burned.  As a locally-produced, 96% recycled content product that sequesters carbon, STAK BLOCKS will also earn several LEED credits for architectural projects

Technology:  Independent  California Polytechnic University Testing has demonstrated the following:

  • Highly insulated: More than three times the value of an insulated 2X6 stud wall
  • Seismically strong:  better than wood framing and less brittle than concrete walls
  • Fast to assemble: Block dimensions are 12”x12”x24”, easily dovetailing with other common construction modules. Each block weighs only 30 lbs and interlocks.
  • Carbon Offsetting Technology- University testing shows potentially 50 lbs of carbon offsetting for production in China . 

Patents for block and manufacturing process are granted and pending.
