Testing of Ecoflex was carried out in accordance with DIN 38412 Part 30. In this test, the pollutant-dependent immobilization of daphnia in solutions of different concentrations (series of dilutions) is used. The control solution contains microorganisms that are known to biodegrade the test polymer. The stock solution at the end of the test also contains the degradation intermediates of Ecoflex .

Petri dish tests are more likely to give an estimate of primary bio degradability than ultimate biodegradability these tests give an estimate of the resistance of plastic to microbiological degradation and the clear zones do not necessarily show the complete consumption of the material but degradation of the polymer bonds.
