Some guy on the Dutch forum thinks that NP biopellets may be resins made by Mirel/Metabolix. NatureWork makes most of the PLA pellets in the market. I can't seem to find a distributor for Mirel. They just opened a huge plant a couple of months ago so the resin should be available in large quantities in the near future.

There seem to be a confusion on carbon here. When we talk about carbon-dosing in this setting, we are talking about biofuel or organic carbons. These are long chain carbons that living organism use for fuel by breaking the bonds that hold these chains of carbon together. We human and other mammals use glucose as our primary fuel. Various bacteria can use different forms of chained carbons for fuel. Something is biodegradable if you can find a bacteria to eat it. That is why plastic from fossil fuel does not degrade because bacteria cannot use it as fuel and break it down. The final product of carbon biodegradation is CO2 which has only one carbon left. This is also not the same INORGANIC carbon that are in activated charcoal we use to clean our tank water with. So when we talk about carbon leaching, it's with inorganic carbon and totally unrelated to this discussion.
