TecEco Home

Welcome to the global hub for the exciting new TecEco sustainable technologies including:

• Tec-Cement - A more durable cement for pre-mix concrete that greatly reduces shrinkage.
• Eco-Cement - Environmentally friendly cement that sets by absorbing CO2.
• Enviro-Cement - Superior cement for toxic and hazardous waste immobilisation.
• Tec-Kiln - A more efficient kiln for making making calcium and magnesium oxides from their carbonates without releases.

TecEco's technologies are part of an ambitious yet uniquely profitable and politically acceptable solution to the problems of global warming, water and waste we call Gaia Engineering which is a tececology that can save our planet by changing materials flows and thus underlying moleconomic flows.

Gaia Engineering involves technical change rather than politically unacceptable carbon constraint and starts with a third party process to sequester carbon dioxide using the magnesium and to some extent calcium contained in bitterns, seawater or brine. To date there are many candidate methods that all require further research and development including the Greensols process which involves chemical precipitation, a pyrohydrolysis process that can be run in association with salt manufacture, an ultra high speed centrifuge process and biomimetic processes.

The solution to our problems with carbon dioxide and other wastes is to invent technical paradigms that convert them to resources. TecEco will provide essential economic drivers for producing man made carbonate by providing markets as building and construction materials and John Harrison our managing director has pursued this paradigm with his invention of Eco-Cement

Our Mission

To solve global environmental problems including excess carbon dioxide in the atmosphere, the waste and water crisis.

Humans are too many and our influence too great. We must therefore accept our role of maintaining “spaceship earth” [1] as planetary engineers and find ways of maintaining the level of carbon dioxide, oxygen and other gases in the atmosphere at desirable levels.

Our technical world, the techno-sphere, is not a closed system and our take and waste impacts are disturbing the homeostasis of earth systems. As in natural ecological systems we must learn how to make our outputs our inputs and achieve balance.

We are hooked on fossil fuels and cannot possibly arrest the alarming increases in carbon dioxide currently occurring through efficiency, emissions reduction or sideways substitution by for example renewables. We must make some fundamental bottom up changes as well.

There is a good chance of preserving the future if we mimic nature by finding uses for carbon and other wastes that are profitable as a large number of people will as a consequence wish to engage. Building with anthropogenically created man made carbonate and wastes is politically acceptable, doable, invokes a market that is insatiable, large and indefinitely continuing.and most likely presents the only option we have for saving the planet from runaway global warming.

Apology

We apologise that we cannot answer all of the thousands of emails we receive. Our main mission must remain convincing the powers that be that a long term solution to the global warming problem must involve a technical capacity to remove CO2 from the air profitably. If you are determined to use TecEco technology to build an exemplar or help us by providing research and development funds please contact us and we will endeavour to respond as soon as we can.

9th of May 2008 - Various Press Regarding the Claimed Invention by Dr Cheeseman of Imperial College of our Technology

In an article dated 1 May 2008 published by CNPlus, the on line newsletter of Construction news in the UK and that has also appeared in a feed to aggregateresearch.com, it was reported that a Dr Chris Cheeseman of Imperial College London claimed he had invented a new carbonating magnesium oxide cement. The offending articles are available at http://www.tececo.com/rdandd.thirdparty.php as links in the text on that page. TecEco utterly reject the contents of the news story as being totally incorrect. According to the report "while carrying out research on one such compound the Imperial team stumbled upon the fact that the resulting cement also absorbed further CO2 from the atmosphere as it hardened." TecEco achieved this some years ago and has reported on the fact ever since. It would seem that the only thing the researchers at Imperial College have stumbled on is the truth. John Harrison of TecEco invented Eco-cements which are magnesium oxide hydraulic cement blends that in permeable substrates harden by taking up CO2 and water from the air. This fact has been widely reported by the media around the world, the first major story being by Fred Pierce who wrote "Green Foundations", published in New Scientist Magazine, vol 175 issue 2351, p38 on the 13th July, 2002. Further media reports confirming Mr Harrison's invention are available at http://www.tececo.com/media.php. Archives of the TecEco web site describing cements that match Dr Cheeseman’s so called discoveries are available on web archives of TecEco going back for years. Dr Cheeseman telephoned Mr Harrison on the 8th May 2008 and claimed that the report was incorrect and not his doing. This excuse has not been confirmed by Mr Alasdair Reisner the publisher who states that Dr Cheeseman made it clear to him that his team had invented something new. As Dr Cheeseman has had little experience with our cements and not collaborated with us and our patents and formulation know how both have very wide relevance we do not believe anything new or that we have not anticipated has been invented by him. TecEco surmise that Dr Cheeseman's incorrect claims appear to be a ploy to attract funding and we further therefore comment that systems that force academics to be fiercely competitive in a commercial world they have little understanding of is bringing out the worst in them and that if we are to solve the urgent problem of global warming a much more collaborative approach is required. As the true inventor Mr Harrison is aggrieved by Dr Cheeseman claims, particularly as he met Dr Cheeseman in 2003 and 2004 and described the TecEco innovation to him and at conferences he attended. Dr Cheeseman was further given samples of carbonating magnesium cements by Mr Harrison during this period. As the new Imperial College spin off company to develop the cements is called Novacem and Nova suggests "new" TecEco do not believe Dr Cheeseman's claims that he was not trying to claim credit for the invention of the cements invented by Mr Harrison. We therefore warn him and others that they cannot reinvent history and reserve our options to take further action if necessary. As of the 9th May 2008 TecEco are waiting on complete written retraction that has been promised and when this arrives it will be published by us.
