Abstract: The method for preparing a homogeneous biodegradable mixture is described for production of shape-bodies. Reinforce fillers are fibers from various natural sources especially those wastes from varieties of manufacturing. Long thin fibers are obtained by longitudinal abrasion of bamboo waste. Boiling the fibers in water for 20 minutes at pH 8 where supernatant is decanted helps getting rid of chlorophyll. Fibers are further ground to preferable length of 2-4 mm. The treated fibers were mixed with all other ingredients in a rotor, spinning at a speed 1,800-2,000 rpm at ambient temperature for 510 minutes. Starch particles and other ingredients penetrate and mix thoroughly with the fibrous materials. Water is gradually added while kneading to form a perfect dough ready for manufacturing of the desired shape bodies.

Abstract: A non-synthetic biodegradable starch-based composition is described comprising starch, plasticizer, reinforcing filler, binder, in the presence or absence of alkali or salt, and water. The starch-based composition is subjected to transformation process to produce various foam-liked products, having closed cell structure with dense skin layer. These products are particularly suitable for use as disposal or single-used food packages or containers. These products are to substitute the shape bodies currently used made of plastic or plastic foam. A transformation process of the non-synthetic biodegradable starch-based composition into various foam-liked products is also described. The process is either injecting or compressing the starch-based composition and forming a desired shape in a closed mould at a temperature ranging from 150 to 300 degree Celcius until the gelatinization of starch has been accomplished.
