Under composting conditions, plastic bags can be degraded into water and carbon dioxide by microorganisms, without any toxicity or secondary pollution to the soil. For example, bags made of polymer materials such as PBAT\PLA\PCL\PHA.

Degradation under composting conditions: moisture content above 95%, soil, temperature (28-58 degrees), specific microorganisms.

Materials that can only be degraded into small fragments and cannot be converted into water and carbon dioxide within a specified time. Photo-oxidative degradation (d2W, P-Life, etc.) adds 1-2% photo-oxidative additives to traditional PE materials. There are also PE and starch mixed materials, in which the starch part can be degraded, but the remaining PE part still cannot be degraded.

According to EU and national standards, more than 90% of the resin components must be biodegraded into water and carbon dioxide.

Infrared spectroscopy (comparing molecular structures) can be used to quickly identify the composition of plastic bags; chemical cracking can also be used (biodegradable materials can be cracked quickly under hot alkaline conditions, while ordinary plastic bags will not crack)

12 months in sealed condition (protected from moisture, soil, light, etc.)

PLA is a polymer material made by converting starch into lactic acid monomers through fermentation, and then polymerizing it into polylactic acid through chemical polymerization;
PBAT is a polymer material made by polymerizing adipic acid, terephthalic acid, and butanediol through chemical polymerization;
Both materials can be biodegraded into water and carbon dioxide under composting conditions.

PBAT has excellent flexibility, processability, and resistance to high and low temperatures, and can meet the needs of film applications. In addition, PBAT has a wide source, is easy to mass produce, and has low cost, making it an excellent product to replace polyolefin materials.

Industrial compost is an organic soil conditioner obtained by biological decomposition of a mixture. The mixture is mainly composed of plant residues, and sometimes contains some organic materials and certain inorganic substances. The raw materials for compost can be organic solid wastes in urban and rural areas, such as agricultural crop straw, rural livestock manure, urban domestic garbage, kitchen waste, municipal sludge, food industry waste residue, etc. Composting, a treatment method for producing compost, is a biochemical process that uses microorganisms that are widely present in nature to controllably promote the conversion of degradable organic matter in solid waste into stable humus. Composting can be divided into aerobic composting and anaerobic composting according to the growth process of microorganisms and whether oxygen is provided. Aerobic composting is the process of decomposition of organic matter in the presence of oxygen, and the final products are CO2, H2O, heat and humus. Anaerobic composting is the process of anaerobic microorganisms degrading organic matter into CH4, CO2, H2O, heat and humus under anaerobic conditions. Composting usually refers to aerobic composting. Industrial composting refers to the process of aerobic mesophilic or thermophilic degradation of solid and semi-solid organic matter by microorganisms under controlled conditions to produce stable humus. The general cycle is 180 days, but with the changes in aerobic composting technology, the shortest time can be 30 days or even shorter.

Home composting refers to the process of aerobic composting mainly using household kitchen waste or garden waste to produce compost for home use. Home composting takes longer than industrial composting, but generally does not exceed one year.
Whether it is industrial composting or home composting, the organic waste it treats should have the following characteristics:
a) Biodegradability (i.e. the original biodegradability of the material);
b) Disintegration performance during composting;
c) No adverse effect on the biodegradation process;
d) Adverse effect on the final compost quality, such as: excessive harmful elements

The delivery time for biodegradable bags/CPE/PE/recyclable plastic bags is 15 days;

The delivery time for viscose bags/glassine bags/cotton bags is about 20-25 days;
