Johannesburg - Changing the Paradigm

The United Nations will stage its biggest conference yet when the World Summit on Sustainable Development starts in Johannesburg next week. More than 60 thousand people and one hundred heads of state and government are expected to be there.

According to the Global Environment Change Report[1] many countries are beginning to feel the apparent conflict between the need to reduce greenhouse gas emissions and the potential threat such reductions could have on economic growth. A viable way forward and out of this dilemma splitting many nations is sequestration, which involves the capture, separation, and storage or reuse of carbon.

The built environment is our footprint on earth and accounts for approximately 40% of all materials flows, emissions and energy consumption. TecEco have developed low cost magnesium carbonate cements with the potential to transform the built environment from a producer to a net consumer of carbon dioxide (CO2). The Eco-Cement formulations developed by the company use high proportions of wastes but not much energy and the positive impact on global climate, pollution and housing for the masses is potentially huge.

Projects are in place exploring terrestrial and geological sequestration however it is widely believed that the oceans may become the eventual repositories of CO2. Unlike creating artificial algal blooms or pumping CO2 into the oceans the TecEco technology is terrestrial and does not appear to have any downsides whatsoever and therefore must be considered as a priority. TecEco contend that It does not make sense to tinker with ecosystems we know little about when we can store the major proportion of annual atmospheric increases in CO2 of some 12 billion tonnes[2] in our own ecosystem, an environment we know a great deal about, understand and can monitor.

Putting vast tonnages of carbon dioxide into sea water will reduce the pH, locally and perhaps even on a wider scale. There will also be other effects, the full extent of which we do not know.  It makes infinitely more sense to use a technology that cannot affect the wider ecosystem. This is not to say, stop the computer modelling or experiments, on the contrary, putting C02 and fertilizers to stimulate algal growth into oceans may well prove viable in the long term, but the experiments should be performed in closed systems before committing the wider ocean environment to change.

TecEco won the Tasmanian Innovation of the Year award and was featured in the July 13th 2002 issue of the international New Scientist Magazine and in many other publications around the world. John Harrison, the managing director, has also appeared on ABC National Television and spoken on several talk back shows.

Consider the tremendous positive ramifications for Australia with it's vast magnesium reserves and for the world of this new technology and if in a position to do so - do all you can to make sure the debate of sequestration takes a more sensible wider approach at Johannesburg. It is essential that we get the message to the conference before the juggernaut of scientists supporting the ocean CO2 repository concept or algal bloom ideas have their way without the appropriate scientific diligence.

Complexity is not an issue - the TecEco Eco-Cement technology is basically simple and easily understood. It does however require some lateral thinking. Resources are not an issue. As we have pointed out many times before magnesium is the eighth most abundant element in the crust. Equipment should not be an issue - Eco-Cements can use existing plant and equipment. Energy should not be an issue - Eco-Cements have a very low embodied energy. There are no substantive material or scientific issues, yet why is the adoption of our technology not happening fast enough? The answer in our heads. The TecEco technology is not just an attractive new science - it involves a paradigm shift in the way we think about our built environment. We have evolved in a basically silicate world of bricks and concrete and have trouble contemplating anything else. It is the fear of change that prevents us considering alternative paradigms. I sometimes wonder whether TecEco should be less transparent in the publicity it is generating - after all the end user does not need to know that the masonry brick of block they are using is a carbonate not a silicate. But then 70% of end users are supposed to have green sentiments so we thought we would appeal to them by telling them that change is possible and the simple truth about our technology. Maybe it is just because we are really small and have such huge ideas! If this is the case as I suspect it partly is then to make it happen faster we need to raise capital quickly and that is what we are doing right now.

Tasmania's Environmental Home Expo

TecEco will be exhibiting at the Environmental Home Expo at the Hobart City Hall, Tasmania, with the assistance of Island Block and Paver and I will personally be in attendance on Saturday 24th and Sunday 25th August from 10am to 5 pm. Any offers of some assistance from shareholders and others would be appreciated as standing on that cold floor for two days is not something I relish!


A boat docked in a tiny village. A wealthy tourist complimented the fisherman on the quality of his fish and asked how long it took him to catch them.

"Not very long," answered the villager.

"But then, why didn't you stay out longer and catch more?" asked the tourist.

The villager explained that his small catch was sufficient to meet his needs and those of his family.

The tourist asked, "But what do you do with the rest of your time?"

"I sleep late, fish a little, play with my children, and take a siesta with my wife. In the evenings I go into the village to see my friends, have a few drinks, play the guitar, and sing a few songs. I have a full life."

The tourist interrupted, "I have a business degree and I can help you. You should start by fishing longer every day. You can then sell the extra fish you catch. With the extra revenue, you can buy a bigger boat. With the extra money the larger boat will bring, you can buy a second one, and a third one and so on until you have an entire fleet of trawlers. Instead of selling your fish to a middleman, you can negotiate directly with the processing plants and maybe even open your own plant. You can then leave this little village and move to the city and from there direct your really big enterprise."

"How long would that take?" asked the villager.

"Twenty, perhaps twenty-five years," replied the tourist.

"And after that?"

"Afterwards? That's when it gets really interesting," answered the tourist, laughing. "When your business gets really big, you can start selling stocks and make millions!"

"Millions? Really? And after that?"

"After that you'll be able to retire, live in a peaceful little village by the sea, sleep late, play with your grandchildren, catch a few fish, take a siesta with your wife, and spend your evenings drinking and playing the guitar with your friends!

Patents Secure

We have committed to the following expenditures for registrations and our budget have been adjusted accordingly on the web site


Estimated Cost ($AK)

Cumulative Cost ($AK)




European Patent





















South Africa



New Zealand



North Korea









Eurasian patent



TecEco have raised $A 90K in the last month or so and $A 70K of this has gone to the patent attorneys with the balance on deposit.

We were tempted to patent in every last country. In the end however we were persuaded by our attorney, Brian Gibson from Freehills, Carter Smith Beadle to adopt Pareto's principle and using a criteria of GDP, magnesia production, magnesite reserves and relative cost (including graft) select the 80% of countries that would give us the greatest return costing about 20% of what we could have spent. This meant that we missed out on a few countries like Norway, Vietnam and Indonesia that I would like to have registered the patent in but funds were limited. Overall we have about 80% of the global economic action and I am content with that.

Next year patent financing will not be so stressful as the latest patent intelligence we have is that TecEco will have to find about $ 10 - 15K. One of the advantages of the European or Eurasian patent we have gone for is reduced translation costs and the fact that the individual filing fees for various countries are considerably delayed.

Welcome to New Shareholders

Welcome to a new shareholder - Dean Lisson from Launceston. Dean is president of the Abalone Divers Association and has asked our managing director John Harrison to speak to divers at the end of the month!

Thank you for your support - we will do our utmost to live up to you confidence in us.

JJ's Column[3]

Some people have commented upon the small font size of TecEco's website. I have replaced the style sheet with one that uses relative values. This means that y the font size will be your browser's/OS's default.

TecEco's new site has been put on hold so I can finish another project of mine - CO2 Busters   - a non-profit organisation founded by dad and I. As dad is very busy trying to save the world with his company TecEco, The site has been completely programmed by me!

CO2 Busters was created to help widen the debate on global warming, climate change and sequestration (removing CO2 from the air). Everyone is encouraged to become involved - not just big corporations. A central theme is alternative solutions to these problems.

I invite the TecEco newsletter readers to visit http://www.co2busters.org/ and sample the site. Within a few days it will be possible for people to post their own articles/news and help build up a useful and interesting resource for environmentally related information.

I would appreciate comments and suggestions about the CO2 Busters site. It helps me improve the design/layout as much as possible. Once the code is complete I will do a 'release' on this mailing list.

Lots of Publicity Means Lots of Emails

The response to the article in the New Scientist Magazine Article on the 13th July issue was huge. I have not been able to respond to many of the emails I have received such as the small sample that follows, so in this issue some generic answers that apply to everybody are included.

Thank you to all of those people who have taken the time to contact us. Sensitive business emails are not included and personal email address and phone numbers have been deleted.


Hi John

I have your details. I've got a fair bot of travel planned in the next fortnight but I've looked at the newsletter and am slowly piecing things together. I may email a couple of questions to you as when I am traveling it is often not possible to use a phone at a civilized hour.

Thanks for your input: I can appreciate why you are so passionate about what you do. I believe an environment feature that is coming up shortly will be the best showcase for your technology.

John Harrison: We could do with more staff to help you


Hi John

I did telephone you a couple of months ago. In this email, I am representing Carter Holt Harvey Ltd a New Zealand company but also has large Australian operations and is listed on the Australian stock exchange. The company does have a new venture fund and as part of that I am presently commercializing a patented lightweight concrete. It will initially focus on the concrete market. The major reason for this enquiry is to look for any synergies between what both of us are doing. I have perused the web site and from this brief review, I understand that you are actually wishing to manufacture a replacement cement. I would appreciate an update as to where you are currently up to, including issues of timing, funding requirements etc

Kind regards

John Harrison: I need to get across to all interested parties that Eco-Cements are a system of formulations involving three basic ingredients, a hydraulic cement such as Portland cement, reactive magnesia and a pozzolan. The way in which these basic ingredients are blended affects the sustainability and engineering outcome.


Dear John

As I mentioned on the phone,   (Magnesita SA)   are very interested in your technology. I have sent you by overnight post a brochure that is self explanatory. From that you can see that they would seem to be an ideal candidate. I will send you a fax to 03 62730010 that has all my company details. Kind regards

I'm starting up a Ferrocement construction company and am interested in using your ideas.  Is this available in product form at affordable prices?  In Alaska?


John Harrison: Our cement are ideal for ferro cement boats as they are resistant to sea water. We look forward to the day when we can assist people like you with supplies.


Dear Mr Harrison,

I have just read the New Scientist article on your magnesium based cement technology and am extremely impressed and interested. As a building designer I specify concrete all the time and would be very keen to be able to specify a less environmentally damaging form of concrete. I am a member of the Building Designers Association of NSW, and would be very happy to help raise awareness of your product to our members both here in NSW and around the country. The BDANSW and our national body the BDA of Australia both have strong environmental policies and are pretty keen to hear of such innovations. I have posted a short "heads up" message to the BDANSW email forum telling members of the article, and pointing to this site. Please let me know if you think there is anything we as specifiers of concrete products could do to assist in the development of technology.

John Harrison: Thank you for your encouragement and offer of assistance.



I read the article in New Scientist and contacted Fred Glasser regarding your product. I think it is interesting and would like to find out more, so can you send me - preferably electronically - technical and promotional material?

If you would like to know more about AMEC have a look at amec.com for an overview. (It doesn't jump out to me that our Australian operations are head quartered in Adelaide with a lot of local, mostly MandE, experience around Australia.)

My immediate interest is the practicality/costs of demonstrating the product in the UK. We are not into buying or owning IPR, but we look to make profit from applying technologies for our clients. Do you have any suitable contacts who could make the cement here, and can you quote for imported material. I was wondering if you had talked to Adelaide Brighton Cement about the product. If not we may be able to look at possibilities.

I look forward to hearing from you

Dear John

I wish to confirm my interest in your developments and my belief that Eco-Cement may be able to be developed into a suitable storage medium for Rankine Cycle solar power plants.  In this, it is likely that the lower emissions will be reflected in higher Greenhouse credits for a given project, so that there is a financial benefit for using the cement.

I am speaking both as a researcher at the University of Sydney and as Chairman of Solar Heat and Power.  My University web site is below the email and my background is at http://www.physics.usyd.edu.au/app/research/solar/index.html

We are actively developing solar power plants (see http://www.physics.usyd.edu.au/app/research/solar/clfr.html)

and are currently examining the potential for base load power plants to replace coal fired generation, and would hope to develop the first one before 2007, catering to recent legislation in NSW.

My concept is this: I see the potential for a research programme using your IP as a basis, but with regard to using additives and establishing high thermal conductivity blocks with an expansion coefficients compatible with steel steam pipes.  This emphasis seems different from your current one would generate new IP jointly held, and your partners would be the University, SHP, and possibly the CSIRO (I have strong links there and they are already interested).  We have the resources to conduct the physical project here in Sydney (I realise that you are heavily committed) but I am sure there would be financial benefits accruing to your company during the R and D process, as there would be for the University.

I would appreciate being able to have access to your technical papers such as you can release, and being able to share these with my colleagues from the University, SHP and CSIRO.   In a following email I will send you an invited paper to be delivered in Alice Springs to the Electricity Supply Association in August which is an overview of the local field in solar thermal electricity as we see it.

Our time frame is to develop useful storage for full system testing by about 2005 when we hope to be developing the first storage solar power plants.  It is clear that use of your concrete would require a license from you is these circumstances, and for subsequent production.

I hope the above is interesting to you; after reading any material you can supply, we will discuss the concept here and prepare a proposal for you.  It is probable we will have SHP prepare an economic model of the storage system before proceeding with the research project.

Best regards

Dear Mr Harrison,

I have been made aware of TecEco through a recent New Scientist article, and have since had a look at your website.

I am interested in pursuing options for possible uses for Tececo products on our campus, in particular and in the first instance, for paving applications

I am in the process of preparing schemes for a major new entry to the University of Otago, which will involve large areas of paving.

The University currently uses coloured concrete paving blocks for this type of application, and the blocks readily meet our requirements for strength and non-slipperiness. The colours however leach out faster than the pavers abrade, and after a few years the pavers assume colours which are soft variants of cement grey.

To retain pattern in our paving, we use different paving modules, and provide inserts of other materials eg stone slabs. We make only limited use of fired brick pavers, as suitable local supplies are not readily available and slip resistance is more problematic.

An area not addressed in your website documentation (well, not yet as far as I can see, and understandably) is the detailed finishes available for TecEco cement -based paving blocks.

- what are the prospects for colour fast formulations?

- what are the likely ingredients for a stable and sufficiently strong (for vehicle loadings) brick-sized paver?

- what is the current cost compared to Portland cement pavers?

- given favourable and suitable answers to the above questions, how best can I enable the manufacture and supply of paving blocks to this site (University of Otago, Dunedin, NewZealand) within a few months time?

I would be most grateful to receive your comments with regard to these questions.

Tried to call you yesterday. I have another slot on national TV next week. Today went well. Can you just explain in really simple terms how we can build our project using Eco-Cement ie what are the simple steps we will have to go through and the likely costs. If you have the info to hand - it would be great to know the carbon footprint for Portland versus Eco-Cement. This is what you would sell eco- cement on. Many thanks for this exciting feedback.

Dear Mr Harrison:

What a wonderful invention! Just chanced upon the NEW SCIENTIST (13 July 2002). A geologist pal, Dr. James R. Underwood, jr of Austin, Texas, USA, has devised a new classification of rock planetary rock types that includes "Anthropic Rocks" along with the usual (sedimentary, metamorphic etc). His e-mail: jrujr@flash.net. I've notified him and several other persons vitally interested in "Geo-engineering"--the correction of man-made environmental problems through technologies--but he may be out of town (new grand-child!). I wish you all the luck in pursuit of your goals. FYI my cv is attached. Have a great week!

Dear Mr Harrison

I visited your web site, after a message from Green Leap.  I think that this looks a fascinating venture.  My interests are derived from tow areas, firstly I have spent a lot of my professional career in the cement and concrete industry working with an US concrete additive company as a business development / engineer and technical support.  I left this industry to complete an MBA at Monash Mt Eliza, where I spent a lot of my time looking at developing a package to assist in the decision to reduce greenhouse gases and general sustainable development management.  I am now working as a consultant in the renewable energy field and in general business management.

If you have any information that is of interest I would really like to look at it.  I am particularly interested in the technology and chemical reactions!

Conversely if I can be of any assistance for you, please drop me a line, my technical knowledge of OPC and Extenders is rusty but good, I did a lot of practical work in this area, I am also aware of some of the cocktails that can improve the plastic properties of a mix.  I have also retained a network in the industry and may be able to give you some feed back in the local marketing!

All the best

John Harrison: Regards to you to Emanuele.


Dear Sir

I am very interested in your new magnesium based "Eco-Cement", however I would like a few clear facts in order to clarify a few things. I hope that you can help me or at least direct me to the appropriate source of information:

Over a time-scale of say one year, how much Carbon Dioxide would enter the atmosphere if standard portland cement was used in all the global production of concrete. This is based on the CO2 produced during manufacture offset against the carbonation process for the year.

The same question but for Eco-Cement!!

I would like to make a direct comparison of the two cements in terms of percentage of CO2 annually saved by using Eco-Cement.

Further to this, it is important to relate this back to the quantity of Carbon Dioxide that is Globally produced by man, therefore, what fraction of the annual global emission of CO2 is the quantity of CO2 saved by using Eco-Cement for all concrete structures.

I hope this makes some sense!!

Many Thanks

John Harrison: Adam - I am hoping you will find the answers to your questions, or at least how to calculate them in our  newsletter 20 and 21. We also have a proprietary spreadsheet I will sent you in due course that will do the calculations for any formulation involving Portland cement, reactive magnesia, a pozzolan and aggregates.


John, I am a prospector in Northern Ontario Canada. My partners and I have several millions of tons of Lizardite. It is a  member of the serpentine family of rock and apparently has the same heat resistant properties as now outlawed asbestos.

The lizardite runs an average of approximatly fourty percent magnesium.

Could this material be used in the manufacture of eco cement?

This deposit is for sale or option. We staked the claims recently and the rock is at surface and is easily accessible. A major railway and siding bed is located over top of the deposit and a highway is one kilometer distant via an existing heavy duty haul road directly from the deposit.

Perhaps if the lizardite cannot be used in the production of eco cement you may know of other uses due to its heat resistant properties. It seems that the world is looking for an alternative to asbestos and deposits of fibre free material with the same characteristics are very rare if they exist at all with the exception of this one. The railway opens the door to transportation to the United States as a possible market.

I found the article in the Toronto Star newspaper regarding your Eco Cement very interesting.

Thanks for reading this.

Hoping to hear from you

Garry Windsor

John Harrison: Garry, we are not in a position at this point in time to discuss your mine but one or two of the strategic partners we are forging may well be. I will let them know.



I read about your eco cement development in New Scientist with interest. We develop street furniture and architectural related products for a range of clients. I am interested in potential applications of your products in this sector. Could you let me know the status of your developments with an idea of when the product may be available in the UK. We would be interested in assisting its commercialisation here.

Very glad to learn about Eco-Cement. I am an architect and a structural engineer from India and now, migrated to USA. At present, living in Atlanta.

I feel oxychloride may be quicker to set and will provide high strength and magnesium carbonate or portland cement. Would be glad to listen your comments.


John Harrison: Ashvin - Check out newsletter 20 available on the web site in which I discuss Sorel type technology in relation to TecEco Eco-Cement technology.


Hi John

Got a call form Vic today looking for you. A lady is building and wants to know who what when as a result of new scientist...nice to know she rang me first ..I have sent your details to her and they will network you to a group of enviro architects...the ball is definately rolling...well done

John Harrison: Thank you for all your support. You're a champion!


Good Afternoon Mr. Harrison,

Being in the industry and recently reading some of your company's literature on the above, I would be interested to find out more about the product and it's applications.

As background Mississauga is Canada's 10th largest city (population) and 7th fastest growing (residential/commercial construction) and as such we would be most interested in new technologies that prosper economic and environmental benefits to our residents.  As such any information you could forward to my attention would be most appreciated.

I represent a carpet manufacturing mill in Queensland.

We are involved with the E.P.A  and its Waste wise program as well as representatives from other local government and private sectors as result of our commitment to reducing landfill waste.

I assume that "Tececo" has had experience with waste materials generated by carpet manufactures, if not please consider the following.

Northstate utilises synthetic materials of approximately 1.5 million kg's of imported polypropylene and nylon fibres and 270 thousand kg's of backing per annum, a total of 1.8 million kg's. Naturally there is a degree of scrap after all production and it is this scrap that we wish to eliminate from becoming land fill.

I estimate that we are in a position to supply "Tececo" approx 2500 - 3000kg of mixed synthetic fibres and backing per month.

We are also looking at shredding and supplying finished carpet into the future where the volumes will be enormous.

I would very much appreciate if you could get back to me and advise if you feel that the above mentioned materials would be suitable to support your business.

Thanking you in advance.

Mike Davis


John Harrison: TecEco are very interested in this kind of waste - we will be emailing you for a sample as soon as possible.


Dear John

My name is Drew Smart. I was told about your product by someone that saw your product on the TV. The person thought it may be of some interest to me as my company manufactures a light weight rock from cement products. Please go to www.smartrock.com.au This will explain more about us.

Should you see reason for us to get to know your product better, please let me know,

Kind Regards

I work for the New York City Transit Authority (the subway system) and we have a very strong green program.  I would like to see if I can get them to use/consider your product (not in that order). I think that to do that I would need the material specifications and information on acquiring either the technology here or receiving the product from you.  And of course information on how much CO2, money, whatever, can be saved.  People there are very paper oriented which is why printed information would be useful.

Dear Sir,

We have been requested by one of our prospective clients to help them with the handling, treatment and disposal of fly ash.  The fly ash, which is a result of burning residual oil of electricity generation process, is presently being directly dumped in 65m X 10m X 4m pits. 

Due to the seepage of rainwater into the ground the fly ash has begun to contaminate the ground water.  At the moment there are about 40 of these pits.  The authorities are now looking for a technology or contractor that is able to solidify the fly ash into an inert form which will then prevent further and future contamination of the ground water.

Since we have been made to understand that your firm has the necessary know how to solve this problem please let me know how do you propose we proceed.  However in the event that it is not within your ascope of expertise, I would be most grateful if you could recommend  some other companies that in your opinion might be able to assist us.  My contact details are listed below and I therefore look forward to receiving your reply soon to enable me to act accordingly.

Thank you and best regards.
