“A new machine dubbed the “Black Phantom” can turn biomass into manmade coal.
Carbonscape, a New Zealand-based start-up, describes its invention as an industrial-sized microwave that can cook plant waste, wood waste, and “even sewage” into coal.
Carbonscape also claims that the machine captures and stores more carbon than the amount of carbon generated by the electricity needed to power it for the process. “
