Compost weighing method biodegrader
Model：MODA-6
Product use:
1. It can be used for the biodegradability analysis of degradable plastics and other bio-based materials;
2. Meet GB/T 19277.2-2013
3. Meet GB/T 22047-2008
4. Meet ISO 14855.2-2018
5. Meet ISO 17556-2012
Product features:
1. The sample is degraded in the active compost, and the air passes through the active compost under controlled conditions.
2. The released ammonia and water are removed, and the released carbon dioxide is absorbed by sodium lime (sodium hydroxide).
3. The carbon dioxide released is calculated by the weight increase of soda lime.
4. The reaction column can be controlled at the temperature specified by the user.
5. If ISO14855-2 is followed, the temperature is usually maintained at 58 ℃.
6. Samples are weighed regularly during the test.
Product principle:
Under the condition of 55-60 ℃, the air that removes carbon dioxide is continuously supplied to the reaction chamber. The samples to be analyzed in the reaction chamber undergo biodegradation reaction through respiration under the action of microorganisms, and oxygen is discharged into carbon dioxide through respiration, which is absorbed by alkali lime. We calculate the biodegradation rate of the samples by weighing the change in the weight of alkali lime.

Case study:
1. According to ISO14855-2, three tests are required to evaluate biodegradability:
a) Use only compost (blank),
b) Compost mixed with standard (cellulose),
c) Compost mixed with samples of interest.
2. As shown in Figure 2, the results obtained by T6 are considered repeatable.
