The first patent application of the company deals with an improvement in its present product mix. It improved the technique involved in the preparation of the bioplastics and the technology utilized for making its starch/hybrid blend in order to produce an injection moldable, waterproof, food safe and thermoformable mix containing 70% biomass. The improvement meets the requirements of its new processing equipment located at its US production facility located in Wilsonville, Oregon. The new improvements will result in better formability, reduced level of cost, higher level of biomass content and improved strength.
The company’s second patent application deals with the introduction of a new technology in the US. The technology utilizes a mix of bioplastic that employs the spin-offs of agricultural industry such as feedstock, soybean hulls and wheat chaff to manufacture a plastic that is 100% fossil fuel free. The new biomass assists in the production of deliware that bears the qualities of paper but produced economically like a plastic paper. The resultant substance is safe to use with food and water proof but free of petroleum. The mix is suitable for the manufacture of plates and trays needed for the perishable food products servicing and other normal packing usages.
