In U.S. Patent 7,647,957, Infinity Board, LLC (Seattle, WA) details a method of producing a virtually fireproof plywood from perennial grasses such as Arundo donax Ligneous, various bamboo strains, or a blend of the materials.

This is accomplished by first weaving the stalks of these plants into a mat and then layering these mats and binding each layer with any one of several commercial resins mixed with potash for the purpose of enhancing the board's fire retardant quality. The result is the formation of a finished product with structural board attributes and an exceptionally high flash point in relation to other manufactured board products made from forest materials, according to inventors Rasul Pasha and Abdulnaser Abdulmalik

Recent refinements in resins and techniques for plywood production in the US, improving cost efficiencies, are directly transferable to Arundo donax and bamboo layering. With the innovation of adding cost-efficient nanoscience technology and materials to substantially enhance fire retarding qualities, Arundo donax and various strains of bamboo suitable for plywood production are poised to have a significant impact as the next generation of structural building material for sustainable development.

Pasha and Abdulmalik developed a method for making virtually fireproof plywood and dimensional lumber products from Arundo donax Ligneous and/or a variety of bamboo strains by employing nano-science materials (specifically potash) to be mixed into the resins used for binding the layers of the ply-board and board-like products together.

Infinity Board provides an improved method for making an environmentally agreeable structural plywood that satisfies the need for sustainable, highly fire-retardant and insect-repellent materials for the building construction industry, thereby lessening dependency on building products made from trees.

The inventors also can also make an oriented strand dimensional lumber product such as the standard American 2 By 4's and 2 by 6's, etc. with all of the inherent advantages of Arundo donax or bamboo.

The combination of both structural board and dimensional lumber made from green materials utilizing this innovative method meets the objective of the inventors to provide a "total green" building system.

These materials are ultimately designed as structural board and dimensional lumber products, but may also be used for other construction purposes which are non-structural in nature and in various other industries where they may be beneficial. An example is the marine industry because the raw stock (Arundo donax or bamboo) is highly water repellent.

Bamboo will provide a cost effective material superior in performance to wood for the manufacture of engineered building products such as I-beams, laminated beams, roof truss and forming materials for concrete.

Bamboo and nanotechnology will satisfy the need for long-lived building and consumer products such as non-structural panels for wall dividers, temporary dividers, cabinets, countertops, cutting boards, furniture, shelving, tabletops, packaging and crates, pallets, window frames, furring materials and finish flooring panels for decoration.
