What is the principle of biodegradable materials for fully biodegradable dog poop bags?

As living conditions improve dog lovers can't help but take their little cutie out for a spin every day!
Then there is the problem of how to clean up the dog's poop.
Most people think that dog poop can be used as fertilizer for the lawn, but this is not the case!

Dog poop is not fertilizer.
----
Many people think that dog poop can be used as a natural fertilizer to bring nutrients to the grass, but that's not actually the case.
Dog poop has a lot of bacteria in it and if the owner doesn't pick up the poop after the dog poops
The bacteria from dog poop is carried to the groundwater and can contaminate rivers, lakes and beaches and can destroy the entire ecology of the land.

Dog poop is so harmful, so as gluttonous poopers we definitely need to clean up our dogs' poop when we're outdoors.
What is more feasible is to use special, fully biodegradable dog poop bags and throw it in the trash.
Not only does it not get your hands dirty but it's also very convenient and fully biodegradable and environmentally friendly!

So what are the ingredients used in fully biodegradable dog poop bags?
Fully biodegradable shit bags are made of a new PBAT+PLA+starch based material This material is used under certain conditions
This material can be biodegraded into the water, carbon dioxide and organic fertilizer through oxidation, which is fully in line with the current international trend of environmental protection and can effectively solve the problem of waste disposal.

And what is the degradation principle of fully biodegradable products?
Biodegradable products, as the name suggests, are plastics that can degrade and under certain conditions can be completely transformed into carbon dioxide, water and other small molecules of biomass that do not remain in the environment and cause white pollution.

Biodegradable products change in physical form from large pieces of plastic film to small pieces of plastic debris under various actions of microorganisms, natural environment, etc.
more conducive to the attachment of microorganisms.
At the same time, the long chain structure of degraded plastic becomes short chain, which is easier for microorganisms to digest.

At this point, degradable plastic completes its full cycle in nature, turning from petroleum or plants into molecular monomers, then polymerizing the monomeric material into degradable plastic and processing it into various plastic products, and finally, under the action of the microbial environment, transforming into water, carbon dioxide, biomass, and returning to the natural environment in another harmless form.
