[Stoves] Adding value to charcoal from TLUD stoves

[Energies Naturals C.B.]

Dear Rajan ,

your findings are very interesting.Just a few questions:

You say composting devellopes faster than normal with activated char. Compared to what?

Do you or does anybody have an idea why this could be ?

How do you prepare your compost?

Thanks and have a good sunday.

Rolf
