What's the difference between biodegradable vs. compostable?



Role: Designer

Please help to explain the difference between biodegradable vs. compostable materials. I have read through several definitions but am still not quite clear on it. Both seem to end up with CO2, H2O and biomass, while biodegradable will be degraded by microorganisms. But some compostable material might be involved with microorganisms as well. Is this right?

Please share some examples of materials in these groups. Many thanks!
