Laurel Biocomposite opens pilot plant

News International-French

28 Nov 2011

The Nebraska-based company opened a new pilot plant this month and shipped Bio-Res™ pellets from its first production run to a major customer for trials.  The manufacturer will test the odorless bio-material to develop enhanced adhesive applications for home products.

These trial results will contribute to the database established by customer-tested Bio-Res-based injection molded parts which show a 10 percent increase in stiffness and tensile modulus.



These improved performance properties are due in part to the material’s ability to lower specific gravity when compared to conventional fillers like calcium carbonate and talc.  Bio-Res cost-effectively raises the renewable or “green” content of plastic products by as much as 40 percent. The product provides a direct replacement for traditional petroleum-based resins in a variety of manufacturing processes for plastics.



Made from corn-based distillers grain, a non-edible by-product of ethanol plants, Bio-Res is produced using a two-tank batch system.  Distillers grain is fed to the tanks which sequentially feed a single positive displacement pump that discharges to a decanter. Once the material completes the drying process it is milled and made ready for shipment to a pelletizing operation.  During processing Bio-Res sequesters carbon dioxide and does not use toxic compounds. The plant is currently producing 250 pounds of the bio-material an hour.  Production could reach 1,000 pounds an hour by the end of the year based on customer demand. 



Bio-Res is available in a powder or pellet form and mixes easily with polyethylene, polypropylene, polylactic acid and PHA.   Bio-Res pellets are made of 60 to 80 percent bio-material.  Injection molders can insert the pellets directly into injection molded parts to reach desired levels of bio-content. The material can also be blended with various resins.  Bio-Res is especially suited for use in a range of industries including shipping, lawn and garden, agriculture and automotive applications.
