One way to make more environmentally friendly housing

By John Harrison - posted Friday, 15 March 2002


Current emissions from clay bricks:

4.26 million tonnes produced X emission factor of .28 tonnes CO2 = emissions of 1.20 million tonnes.

Reduced emissions from clay bricks if substituted by eco-cement bricks

4.26 million tonnes produced X emission factor of .0375 tonnes CO2 = emissions of some .1597 million tonnes.

By subtraction the abatement would be over a million tonnes CO2.

Consider now the situation with concrete blocks:

Current emissions from concrete blocks:

2.76 million tonnes produced X emission factor of .05 tonnes CO2 = emissions of .138 million tonnes.

Reduced emissions from masonry units if substituted by eco-cement bricks

Advertisement

2.76 million tonnes produced X emission factor of .0375 tonnes CO2 = emissions of .1035 million tonnes.

By subtraction the abatement would be over .0345 million tonnes CO2, somewhat less but still significant. If waste organically derived fibres are also used the abatement could be .138 million tonnes or more, somewhat more significant.

The above are significant claims so consider our credibility:

TecEco Pty Ltd have received endorsement by leading scientists around the world including Dr Kwesi Sagoe-Crentsil from CSIRO Building Construction and Engineering and Professor F. P. Glasser of Aberdeen University, Scotland and Dr. Leon Burgess Dean of Deakin University in Australia

In an appraisal document, Dr. Sagoe-Crentsil said that "the theoretical basis of the proposed Eco-cement is logical and the economic and environmental benefits appear excellent."

Prof. Fred Glasser, an international expert on cement based materials and ceramics, said, in an academic report titled ‘Cements Based on Magnesium Oxide’, that the technology "represents one of the few recent advances in inorganic cements which are suitable for large volume production."
