Carbon, even that scrubbed and reclaimed from industrial smokestacks as an admixture for concrete has been discussed for at least 20 years and to my knowledge has never been implemented. Since such source of carbon, being a waste product would therefore be essentially free but even so has not been utilitized for this purpose. It is therefore hard to imagine how or why Zenyatta's very expensive product would be so employed. At any rate this MOU provides the excuse to pretend to provide a relevant news release. On the subject of MOU's, not being binding on either party, they are usually recognized in knowledgeable circles as nothing more than a promotional tool.
