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.
A composition for production of a bioplastic that is compostable and biodegradable, the composition comprising about 1 to 99% by weight of post-consumer recycled (PCR) resin, hemp hurd of about 6% by weight, wherein the hemp hurd is a fine powder about 0.25 to 0.75 microns in diameter, and about 0.5% to 10% biodegradation additive by weight.
A composition for production of a bioplastic that is compostable and biodegradable, the composition comprising plant-based polypropylene or plant-based polyethylene from about 15% to about 99% by weight, hemp hurd of about 6% by weight, wherein the hemp hurd is a fine powder about 0.25 to 0.75 microns in diameter, and biodegradation additive from about 0.5% to about 10% by weight.
A composition for production of a bioplastic, the composition comprising about 50% to 99% plant-based polyethylene, PP-Polypropylene or plant-based polypropylene, by weight, and 0.5% to 5% biodegradation additive by weight;
