These swing bin bags completely degrade to H2O & CO2 and do not need to be buried etc for them to degrade fully and so will degrade even if stuck in a tree or in water. The degradation process will be speeded up under the right conditions such as if they are buried in landfill. d2w degradable bin bags are better than biodegradable bags because those need to be in a bioactive environment to degrade.
d2w degradable bags are specially designed to last for their intended lifespan but should not be exposed to excessive heat or light during storage.
