A polylactic acid composition of a dispersion structure using, as a matrix, a lowly crystalline or amorphous polylactic acid having a crystallinity of not more than 40%, the matrix containing, as a pulverization promotor dispersed therein, an organically modified polysaccharide or a lamellar silicate that is swollen or that is treated to be swollen.

The polylactic acid composition has excellent hydrolysable capability and property of being mechanically pulverized.

A plastic composite material comprising coffee grounds is provided. The plastic composite material includes coffee grounds, wherein the particle size distribution of the coffee grounds has a particle size distribution of 94% by weight or more for coffee ground particles having a particle size greater than 250 m and less than or equal to 850 m, and wherein the plastic composite material has a colorimeter value of 4.4 or less.

The present patent application relates to a biodegradable polymer material comprising a biodegradable polymer matrix, wherein the polymer matrix comprises at least one zeolite and at least one biodegradable and/or water-soluble filler.

A composition and method where a polymer is exposed to radiation in the presence of a sensitizer such that at least a portion of the triplet oxygen (ground-state oxygen) in the composition to convert to singlet oxygen by Dexter energy transfer mechanism so that polymer photodegradation occurs by singlet oxygen (.sup.1O.sub.2) photosensitization with oxidation occurring at CH sites and the polymer undergoing a predetermined structural transformation to a biodegradable polymer.

An earth plant-based compostable biodegradable composition for the formation of a bioplastic and method of producing said resin, the composition comprising: about 17.5 to 45% ethanol-based green polyethylene by weight, about 20 to 25% calcium carbonate by weight, about 2 to 12% hemp hurd or soy protein by weight, about 32 to 45% starch by weight, and about 0.5 to 1% biodegradation additive by weight to enable biodegradation and composting of the bioplastic; wherein the composition is produced by first mill grinding the ethanol-based green polyethylene, calcium carbonate, hemp hurd or soy protein, starch and the biodegradation additive into fine powders, then mechanically mixing the fine powders one by one into a final mixture for about 5-25 minutes at a time, dry and without heat, and then heating the final mixture to about 220 to 430 degrees Fahrenheit.

The present invention relates to compostable biopolymer compositions having desirable mechanical properties, strength and transparency. The present invention also relates to compostable biopolymer films and biopolymer sheets having desirable thermoformability, flexibility, mechanical properties, reduced haze that have wide ranging applications as alternatives to single use plastics in the medical and surgical field.
