Those are all closed retorts and don't do double duty as building and process heat suppliers in widely distributed micro-applications, hence, to wit, and therefore not triple-bottom-line qualifying. The business model for using them would be the standard corporate centralized one that externalizes costs and concentrates wealth, without optimizing the non-monetary benefits.

Maybe that is Chinaism?

As far as I know, we have the only top-lit, up draft, continuous process pyrolyzers in existence - which is a key factor in maximizing triple-bottom-line benefits - Americanism! ThumbsUp
