PVA in the soil can be decomposed by bacteria and strains isolated from the soil, and can eventually be degraded into CO₂ and H₂O.

PVA starch materials are biodegradable and soluble under both aerobic conditions (soil, compost and fresh water) and anaerobic conditions (sewage and landfills). PVA starch dissolves in water, forming a glue that penetrates into the soil, increasing the soil's viscosity, air permeability and water retention. It is especially suitable for sandy soil transformation. PVA in the soil can be decomposed by bacteria and strains isolated from the soil, and can eventually be Degraded into CO₂ and H₂O. PVA starch plastic can quickly break down in seawater into extremely soft, tiny and non-toxic powders or fragments that are safe for marine animals. Burning will not produce irritating smell, no harmful toxic smell, slag, or smell like burning paper.
