TRTC/EG is the public business entity that finances and sells NBPlants products. EG itself is an empty shell. All it does is to repackage and rebrand.
I often wonder if early shareholders of TRTC involuntarily financed NBPlant's existing debt thru EG ... and that was where majority of the ~50 mil accumulated deficit came from.
TRTC without EG was once called private secretary whose expertise is public financing with no product of its own.
