RE:CHAR en fuegoWhen TEI partnered to produce its Bio-Char toilet presented at the India new toilet competition - we all expected contracts in Africa.
Mini DryRex dried the fuel fuel for a burner and a FluAce recovered the heat for the DryRex.
I believe BioChar was an output.
TEI did there next project in Kivalina, showing how their process redused sewage.
Best as I can remember...!
