What is compostable plastic? February 19,2021.

compost degradation tester


Disposable tableware, disposable plastic products, and agricultural mulch are difficult to recycle, and the main treatment methods are incineration and landfill. If incinerated, a large amount of harmful gas will be generated, which will pollute the environment. The polymer buried in it cannot be decomposed by microorganisms in a short time, which will also pollute the environment. There are also discarded plastic films in the soil, which hinder the development of crop roots and the absorption of water and nutrients, which will reduce the permeability of the soil and reduce the yield of crops.

After eating the discarded plastic film, it will also cause intestinal obstruction and death. The synthetic fiber fishing nets and fishing lines lost to the ocean or discarded in the ocean have caused considerable harm to marine life, so GBPI R&D team takes care of our global environment as a responsibility. With the orientation of recyclability, easy recycling, and degradability, the compost degradation tester has been developed to enable more materials to meet the requirements of degradability and reduce plastic pollution. GBPI testing experts will take you to learn about compostable degradable plastics and the relevant standards for compost degradation testing.

Compostable degradable plastic refers to the ability of degradable plastic to be biodegraded during the composting process. It must be stated that the material is biodegradable and disintegrable in the composting system, and is completely biodegradable in the final use of the compost. Compost must meet the relevant quality standards, such as no biological toxicity, low heavy metal content, and no distinguishable residues. The compost degradation tester newly launched by the GBPI R&D team can detect the corresponding substances by the composting method, the maximum biodegradation rate under the condition of oxygen supply, and determine the biodegradability of the compost product. The completely biodegradable material can be completely decomposed by microorganisms, which is environmental Have a positive effect.
