Living in a region that is thick with concrete
plants I would be very interested in your source or your findings about the
damage concrete plants do to the environment. Can you please cite your
source or provide any information?
One obvious damage done by these plants is
that they quite literally chew the hills away our limestone here.
Once they start a 1200 foot tall hill can be leveled flat in five years by these
guys. God knows what happens to the flora and fauna that once resided on
that hill. It can be very ugly.

Subject: [GBlist] Fw: A carbon based
built environment
Some three or four years ago I found amongst some
back issues of Environmental Building News a copy of an article about how
disastrous Portland cement is on the environment. As well as the noise
and dust, according to many authors over 10% of anthropogenic CO2 comes from
this source.
The article really inspired me and since that time I have
been working on a carbon based cementitious material. It seemed logical to me
that the way to stop global warming and climate change was to do what nature
has done for billions of years and create our own built environment using
carbon dioxide as a source molecule.
Over two or three years we found
ways of making the technology work and are now producing bricks, blocks and
pavers on an experimental basis. What is exciting is that the bricks utilise
well over 90% of a wide range of wastes and are CO2 neutral or even a net
sink. The potential sequestration is enormous. Even though we know that there
are over 1.8 billion tonnes of Portland cement produced globally each year we
do not know how many billion tonnes of clay bricks and other materials that
could potentially be replaced are produced so we cannot give an accurate
overall figure. According to the Australian Federal department of
Industry Science and Resources in a document titled “Building for Growth. An
Analysis of the Australian Building and Construction Industries ”buildings are
responsible for some 30 per cent of the raw materials we use, 42 percent of
the energy and 40 per cent of the air emissions. So what we do know is that it
would be several billion tonnes. I think we have developed what is
probably the most important technology this milleneum
We believe
that we will be successful because so much less energy is required to make the
new eco-cement resulting in a very low cost base.
If any readers are interested or can help with
statistics etc. more detail are on our web site at www.tececo.com
