Could green building materials also be longer lasting?

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.
