RTK PBD automatic plastic disintegration analyzer


Disintegration tests were conducted under defined, standardized conditions for pilot-scale composting. The test material is mixed with fresh biomass waste in precise proportions and placed in a defined composting environment. The microbial populations prevalent in nature naturally trigger the composting process and the temperature increases accordingly. Composting materials should be turned over and mixed regularly.

Product introduction
Disintegration tests were conducted under defined, standardized conditions for pilot-scale composting. The test material is mixed with fresh biomass waste in precise proportions and placed in a defined composting environment. The microbial populations prevalent in nature naturally trigger the composting process and the temperature increases accordingly. Composting materials should be turned over and mixed regularly. Regularly monitor temperature, pH, and gas composition, which should meet standard requirements to ensure adequate and suitable microbial activity.

The composting process continues until the compost is fully stable, typically after about 12 weeks. The compost is observed regularly from the appearance to monitor the adverse effects of the test material on the composting process. To determine the compost maturation at the end of the test, sift the compost and test material mixture with a 2mm and 10mm sieve. The disintegration of the test material was evaluated by the ratio of the amount of test material fragments to the total dry solids on the 2mm test screen. The compost obtained at the end of the composting process can also be used for further tests, such as chemical analysis and toxicity testing
