One thing that frustrates my home renovation expert and bonafide contractor husband to no end is the shoddy quality of the construction materials, fixtures and other doo-dads that his customers buy at a certain uber home supply company that has managed to put most local hardware stores out of business. Thus the blog I posted the other day about green building products company Serious Materials was inspired as much by a concern over quality as green issues.
GreenTech Pastures reader Dan Barry checked in over the weekend to suggest that the two are linked. He's been reading up on a debate sparked earlier this year that suggests that the pyramids in Egypt's Giza region aren't actually constructed out of pure limestone but rather out of a blend of both cut stones and those that were cast out of reconstituted limestone. It's really quite a fascinating story . And the process described by the article could be an alternative to existing cement production methods, which are known culprits in excess carbon dioxide production.
Read it and think.
