Here is an introduction to how compost - degradable pet poop bags work:

 

• Material composition: Compost - degradable pet poop bags are usually
made of materials such as plant - based polymers (like polylactic acid, PLA),
starch - based plastics, or other biodegradable polymers.
These materials have a molecular structure that is more easily broken down by microorganisms.

 

• Microbial action: When the bags are placed in a composting environment,
microorganisms like bacteria, fungi, and actinomycetes start to act on them.
The microorganisms secrete enzymes that can break down the chemical bonds
in the bag materials.
For example, in the case of PLA - based bags, the ester bonds in the PLA
molecule are attacked by the enzymes, gradually reducing the polymer chains into smaller fragments.

 

• Environmental conditions: Adequate moisture, oxygen, and suitable
temperature are necessary for the degradation process. In a compost pile,
the moisture content is typically maintained at around 40% - 60%, and the
temperature can range from 50°C to 60°C, which provides an ideal environment
for the growth and activity of microorganisms. Under these conditions,
the microorganisms can multiply rapidly and accelerate the degradation of the bags.

 

• Conversion into compost: As the degradation process progresses, the bag
materials are gradually converted into carbon dioxide, water, and humus -
like substances. The humus - like substances can be used as a soil conditioner
in gardening and agriculture, improving soil structure and fertility.

 

In summary, compost - degradable pet poop bags work through the action
of microorganisms in a suitable composting environment, which break down
the bag materials into harmless substances that can be recycled in nature.
