Our Product

From soil to structure, IGS provides sustainable, durable and affordable building solutions.

With an ever expanding population, limited natural resources and a fragile global economy, the need for sustainable and affordable housing is greater than ever.International Green Structures (IGS) develops next generation IGStructures which offer an alternative to traditional block & concrete, and wood-based materials. Our flexible construction technology is easily expandable and will accommodate a variety of sizes and designs – from residential housing to commercial and institutional structures (schools and healthcare clinics). IGStructures can be shipped anywhere globally and are easily assembled within days. All of our solutions meet national and international building codes.


More than 50 million acres of wheat and rice are planted annually in the United States, alone. IGS manufactures Compressed Agricultural Fiber (CAF) panels, which are made from straw, a wasteful by-product of wheat and rice crops that has no potential for fuel or food. Our CAF Panels are USDA Bio-Preferred and meet 2008 Farm Act bio-based procurement requirements. In addition, harvesting straw promotes no-till farming and has a low carbon footprint.

IGStructures can be easily packaged and shipped on common flatbed carriers, reducing transportation costs. Globally, they can be shipped anywhere in the world and assembled within days after arriving at the construction site. Training is provided on the structural installations of all our systems, and our solutions easily expand to accommodate any size or design.


The straw is upcycled into a Compressed Agricultural Fiber (CAF) Panels, a natural fiber alternative to conventional building products. Not only are CAF Boards energy efficient, they are also tested and proven to be:


  • fire resistant (over 2.5 hour fire rating on load-bearing panels)
  • water and mold resistant
  • termite and pest resistant


IGStructures are assembled and under roof in a few days, significantly reducing installation time and expenses. In addition to lower operating costs, IGS panels convert agricultural straw waste into commerce. Our raw materials create a “second-cash” crop incentive for local farmers that drive larger grain harvests, increased revenues and more jobs. In a mass production scenario, we can provide hundreds of jobs to local labor forces to assemble our IGStructures. Training and utilizing local labor forces will immediately stimulate the local economy and strengthen the housing market.
