Opportunities for capital investment in projects sponsored by TecEco exist for appropriately qualified, high net worth, ethical and sophisticated investors. Later when we morph TecEco into a Not for Profit we will try and set it up for crowd funding of research into what matters.

TecEco are developing networks for the research, development and deployment of its Syncarb and Synrock technologies, Tec, Eco and Enviro cements and Tec-Kiln technologies, variously described as a “benchmark”, "sound science", "important" and as showing "much promise" by leading scientists.

The patents are now free to use although we retain as copyright information on this web site. Academics, magnesia producers[1] and cement companies around the world interested in our technology can apply for various options.


The applications of TecEco Gaia Engineering technology are very broad. Companies or governments interested in sequestration, producers of magnesia, cements or coal combustion by products, owners of pre-cast yards, mining companies with wastes, manufacturers of concrete bricks, blocks, pavers, renders, coatings, mortar mixes, patch cements, anyone in the building sector or for that matter anyone at all etc. etc. are all invited to treat with us for the future.
