| Purdue University researchers developed a method for extracting lignin and reinforcing fibers from rice straw for use in composite board manufacturing. Contemporary fabrication of composite binders requires use of formaldehyde or PMDI resin, one poses a health hazards and the other is expensive. To remediate these drawbacks, researchers at Purdue University have developed a process for extracting depolymerized lignin from rice straw, which is then formulated into a sustainable binder. Combination of lignin-based binder with clean cellulose fibers from the reaction produced composite boards with desirable physical properties. A cost analysis shows a significant cost reduction over formaldehyde-free composite board production when fabricating medium density fiber boards. This technology provides a low-cost sustainable, green method for producing composite boards that could deliver higher margins to composite board manufactures. Advantages: -Less Expensive -Non-carcinogenic materials Potential Applications: -Manufacturing -Construction |
