Re: [papercreters] Re: 26lbs of CO2 per bag of Portland

Thats the way I see it piddle a little now or do it for the life of the house with wasted fuel and or electric energy dragons spitting it out. Its all about the overall effect at the end of the road. Now I did do my part to a point I now only use 1/2 a bag of cement replaced with half a bag of s-lime in a load of mix. But I must admit it was more because it cracks less and cuts mildew and bugs down better then anything. Of course thats also helped by the cactus juice to.

off my stump sorry lol

Picture a papercrete builder that uses the worst source of cement,
trucked half way across the country, and uses very cement rich
mixes. Is this the worst possible scenario for Carbon Dioxide in
papercrete construction?

As long as that worst case builder builds a very energy efficient
house, the TOTAL CO2 emmisions associated with that house over its
life span will be minimal.

Compare it to the horribly energy wasteful houses that are usually
built. There are often megatons of carbon dioxide that are emitted
to create the excess energy required to heat and cool standard homes.

Why quibble over a few extra pounds or even a few thousand pounds of
carbon dioxide compared to that?

Keep perspective.
