Disintegration tester - DT Respirometer
How to determine degree of disintegration?
The degree of disintegration is determined by comparing the material’s weight before and after the test. During the test, the material is exposed to controlled composting conditions for a specified period. The more material that breaks down during the test, the higher its degree of disintegration.
The DT Respirometer provides controlled testing conditions for biodegradable and compostable plastic materials, allowing the degradation process to be monitored and analysed accurately and reliably.

Modularität
- The biological treatment of biodegradable plastic materials includes aerobic composting in well-operated, municipal or industrial biological waste treatment facilities. Determining the degree of disintegration of plastic materials in a pilot-scale plant is an important step within a test scheme to evaluate the industrial compostability of such materials.
- The disintegration test is performed under defined and standardized composting conditions on a pilot-scale level.
- The test material is mixed with fresh bio waste in a precise concentration and introduced into a defined composting environment. A natural ubiquitous microbial population starts the composting process spontaneously and the temperature increases. The composting mass is regularly turned over and mixed. Temperature and O2 concentration are regularly monitored.
