View challenge: C-7190-0102 - Polymer biodegradation screening tests
We are seeking an effective screening methodology for biodegradability of polymers in soil to precede a 2-years biodegradation test in close-to-real soil conditions.

Background:-

Polymers biodegradation in the soil is affected by multiple factors with intricate co-dependencies: the soil type, the biome of a specific soil sample, geographical location, temperature, moisture, and other factors. Ultimately, biodegradation can only be ascertained in a full long-term test in as real conditions as possible. We are aiming at high biodegradation rates of 90%, or more, in soil over a period of 2 years at 25C.

For practical reasons, we're looking for an accelerated screening test to quickly select the most promising polymers before commencing a full-length biodegradation test. The accelerated test should take into account the micro-organisms activity, the soil medium, the bacteria culture used for the tests, additives that may be used to accelerate the test, and any other factor that may affect the result and make it meaningful, with the ultimate goal of reliably correlating the accelerated test result to the full 2-years test.

Our criteria
