We consider agricultural waste materials such as straw—the stems left after harvesting cereal grains—to be a good alternative to conventional materials. Such materials might otherwise be wasted, and using them makes the most of agricultural crops.

In addition, it can be formed into shapes or grown to adhere to wood veneers and facing materials without needing adhesives. The material can be produced at several densities, has a Class A fire rating, a flexure strength of 501psi, and a screw withdrawal of 110 lbf.

  • KI Chairs with AirCarbon Plastic
    KI
    KI, manufacturer of commercial furniture, offers chair lines made using a petroleum-free polyhydroxyalkanoate (PHA) plastic called AirCarbon. The raw materials used to make AirCarbon are taken from agriculturally sourced methane, thereby sequestering this powerful greenhouse gas. While the standard AirCarbon plastic is biodegradable, the plastic used for KI's chairs is engineered for durability and is not biodegradable. It is carbon-negative and recyclable, according to the company. The Strive and Grazie lines will be the first products to use AirCarbon. They are available as stacking chairs, stools, and in other styles. KI's conventional chairs are Indoor Advantage Gold certified for low emissions; certification is anticipated for KI chairs.

    W. R. Meadows, Inc.
    Premium Insulating Sheathing is a vapor-permeable exterior sheathing alternative to plywood and OSB. It contains 50% pre-consumer recycled wood fiber; 10% formaldehyde-free, rapidly renewable vegetable starch binder; and small percentages of clay, paraffin, and carbon black that provide moisture resistance. These ½" sheathing products cut with a knife and have good sound dampening, an R-value of 1.3 (per ½"), and a perm rating of 23, according to the company. This high permeability is an important feature in climates where wall-cavity drying to the exterior is important.

    Community Power Corporation
    The BioMax commercial-scale combined heat and power system is designed to use woody waste biomass as fuel. Downdraft gasifier technology converts a wide variety of waste biomass residues into a clean fuel gas which is then burned to produce power and heat. The fully automatic, modular system is designed for use with low-cost waste materials such as nut shells and wood chips. According to Community Power Corporation, efficiencies approach 80% in combined heat and power applications, with low emissions and non-hazardous char and ash. BioMax units are available in 25, 50, 75, and 100 kWe capacities.

    Community Power Corporation has also developed a thermal-only system and a system that generates clean liquid fuel using the same waste biomass residues and gasifier technology. While the military is its largest market, the longest operating system of this emerging technology is a walnut farm in California commissioned in January 2008.

  • Kebony Preserved Wood Decking
    Kebony
    Kebony uses a preservation process called furfurylation to increase the durability of maple, pine, and other woods. In the process, dubbed “Kebonization” by the company, furfuryl alcohol collected from agricultural waste reacts with the wood. The company claims the resulting decking, also called Kebony, has the dimensional stability of tropical hardwoods and is similarly resistant to decay from termites and fungi. According to the company stains take slightly longer to cure on Kebony, as it is intended to be installed without a finish. When installed, the wood is a golden brown that slowly turns to a silver-gray. At the end of it’s life, Kebony can be disposed of like untreated wood. The product is manufactured in Oslo, Norway, and imported through their offices in Roanoke, Virginia. The process meets the criteria for the Nordic Swan Label. Some of the wood is FSC-certified.
