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 25% post-consumer recycled polyethylene resin by weight, about 50% plant-based polyethylene resin by weight, about 10% calcium carbonate by weight, about 5% cotton waste by weight, about 7% food starch by weight and about 3% biodegradation additive by weight.
A composition for production of a bioplastic that is compostable and biodegradable, the composition comprising about 5% post-consumer recycled polypropylene resin by weight, about 60% plant-based polypropylene resin by weight, about 12% calcium carbonate by weight, about 10% potato starch by weight, about 10% tapioca starch by weight and about 3% biodegradation additive by weight.
A composition for production of a bioplastic that is compostable and biodegradable, the composition comprising about 10% post-consumer recycled polyethylene resin by weight, about 60% plant-based polypropylene resin by weight, about 15% calcium carbonate by weight, about 12% food starch by weight and about 3% biodegradation additive by weight.
