A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.

A film of laminate construction for producing on a packaging machine a flexible container for containing food includes the following layers. A layer of natural kraft paper for forming an outside layer of the container followed by a layer of adhesive. A layer of PE also known as polyethylene followed by a layer of tie adhesive for bonding two layers together. A layer of EVOH also known as ethylene vinyl alcohol and another layer of tie adhesive for bonding two layers together. A layer of PE sealant also known as polyethylene sealant for forming an inside layer of the container, wherein the layers preferably containing an organoleptic biodegradable additive to accelerate decomposition of the film laminate.

The invention relates to a biodegradable additive for improving the property of a PVA-substituted sizing agent. The biodegradable additive is prepared from the following steps: by adopting agricultural side products and wastes as materials, obtaining a biodegradable mixture by alkaline extraction, and preparing the additive based on the agricultural side products and the wastes; or adopting anhydride (acetic anhydride, butanedioic anhydride and the like), unsaturated polar monomers (crylic acid, acrylonitrile, styrene and derivative and the like) to modify the additive based on the agricultural side products and the wastes, and preparing the modified additive based on the agricultural side products and the wastes; or adopting biodegradable polyhydric alcohol or polyhydric alcohol amine as the materials and preparing a plasticizing additive based on the agricultural side products and the wastes together with the additive based on the agricultural side products and the wastes. The biodegradable additive has the advantages that the sizing property of the biodegradable textile sizing agent for cotton yarns, polyester, cotton-polyester blended yarns and other blended yarn threads can be improved, and simultaneously the degradability of the novel sizing agent is not weakened, so that the biodegradable additive is a green sizing-agent additive with low preparation cost and excellent biodegradability.

The disclosure provides a synthetic biodegradation-enhanced fiber, methods of making such fiber, and articles including such fiber. The fiber includes a polymer material and 0.1 to 10 wt % one or morebiodegradation additives at least partially contained within the polymer material. The biodegradation additives enhance the biodegradation rate of the polymer material in a biodegradation environment. The biodegradation additives may comprise at least one of an aliphatic-aromatic ester, a polylactide, an organoleptic, a monosaccharide, an aldohexose or a combination thereof. The synthetic fiber may be micro-denier fiber have a denier of less than or equal to 1, or macro-denier fiber having a denier greater than 1. The synthetic fiber may be siliconized.

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% thermoplastic 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, thermoplastic 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 360-degrees Fahrenheit.

The invention discloses a production process of rapidly biodegradable micro-porous polyester fibers. A high-temperature foaming agent and a biodegradable additive are added, the biodegradable additivein the micro-porous polyester fibers is fully dispersed and uniformly distributed in high-temperature foaming and decomposition processes, and meanwhile, the micro-porous polyester fibers become a porous fiber material, so that the micro-porous polyester fibers become fibers with the fully dispersed and uniformly distributed biodegradable additive and the loose structure, the fibers are easy to biodegrade, the biodegradation speed is increased, and the degradation period is doubly shortened.
