Dear Andrew, thanks for your response. Your inputs will surely be helpful.

In which medium do you intend to run your biodegradability tests; compost, soil or water? That will inform which international standard method to use.

Dear Osei, I'm interested in doing the tests in compost and soil.

Please do let me know.

Dear Sunny,

Please read the article referred to by Sudhakar above, I've read it and it contains all the standard test methods for biodegradability testing in compost and soil.

Wishing you all the best.
