A naturally degradable vacuum-sealable plastic bag, comprising a bag body, which is composed of layers compounded from a plurality of film layers (1, 2, 3), wherein a receiving cavity is formed in the middle of the bag body, which can be used for storing food, wherein at least one of the layers of film comprises a prodegradant material, wherein polyethylene is contained in the film material for preparing and manufacturing said multiple layers, wherein the added amount of prodegradant material is approximately 5% by weight of the polyethylene.

Thermoformable and biodegradable cellulose acetate compositions comprising at least one cellulose acetate at least one plasticizer, and at least one additional component chosen from a filler, additive, biodegradable polymer, stabilizer, or odor modifier are disclosed. The compositions are formed into films, sheets, and articles.

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.

Disclosed herein are methods for degrading polyurethane foam from mounted polyurethane foam-containing tires, methods for separating a wheel from a mounted polyurethane foam-containing tire, methods for preparing a degradable foam-containing tire, and degradable foam-containing tires. The methods include applying a solution comprising at least one phosphorous oxoacid or an ester thereof to the polyurethane foam inside of a tire, incorporating a degradant comprising at least one phosphorous oxoacid or an ester thereof into the polyurethane foam, or both, and then heating to degrade the foam. Degradation of the foam allows for separation of the wheel from the rubber carcass of the tire.

A method for alcoholising and hydrolysing polyurethane (PUR) materials made from at least one polyol compound and at least one toluene diisocyanate based compound; wherein the method comprises the following steps: contacting the polyurethane material with at least one alcoholising compound, thereby forming a reaction mixture (M.sub.0) and allowing the polyurethane material and the alcoholising compound to react in said reaction mixture (M.sub.0), thereby forming a mixture (M); allowing the mixture (M) to separate into at least an upper phase and a lower phase, wherein phase (A) and phase (B) are two immiscible phases; subjecting phase (B) to at least one hydrolysis step, thereby forming a phase (B1); wherein the at least one alcoholising compound is characterized by a melting point of lower than 200° C.; wherein the at least one alcoholising compound is characterized by a hydroxyl functionality of at least 2; and with the proviso that the at least one alcoholising compound is not glycerol.
