How do you make your Concrete?
VitraStone
products do not use “Portland” cements. Portland
cement [wikipedia] requires large amounts of energy to
produce, according to VitraStone, and they contribute to 7%
of global green house gases. The company uses a ceramic
cement,
which they view makes their concrete stronger to others in
the market. “Ceramic cements are an age old technology, in
fact the mortar in parts of the great wall of China have similar
ceramic cement,” commented Ryan. VitraStone claims their ceramic
cement is very low in embodied energy, about 1/20 of the energy
needed to create Portland cement. VitraStone does not off
gas, and is mold resistant.
In Brazil, one supplier is:

WaterHOG
Text from waterhog.com.au – please

The waterHOG is a slim, rectangular,
modular, plastic rainwater tank which is designed to fit into
the usually empty cavities of the house, for example between
floor joists and wall studs when spaced at 600mm centres.
 The waterHOG units can also be installed like
conventional rainwater tanks, fixed to the side of the house or
to a fence.
The narrow
profile makes the waterHOG a good water storage solution along
sidewalls, down narrow passages and underneath decks and house
structures.
The waterHOG tank is smooth-sided which means that it can
be laid or placed on any of its surfaces when installed and,
however
it’s placed, the water will flow freely between the modules
and the tank will not bulge. It can lie flat, on its side, or stand
on its short end to provide rainwater storage in almost any situation.
The long, low waterHOG tank has a hole in its centre, removing
the water load from the middle and preventing the horizontal tank
from bulging.
A series of waterHOG units (or modules) can be
linked together to form one big storage tank unit. The waterHOG
units can be connected up in any formation to effectively store
rainwater collected from
your roof.
The waterHOG modular tank is rotomoulded in virgin polyethylene
which complies with Australian Standards. This material
is durable and impact resistant, with UV stabiliser and
anti-algae additives
to ensure that the water remains pure and potable. The tank
material itself is recyclable, and the tank carries a 10-year
guarantee.
Each waterHOG tank has a capacity of 180 litres, and has
the following dimensions: 500mm x 220mm x 1800mm.
