Environmentally friendly school

One thing i think people over look with the building of our new school is what we are going to do with the old one. Obviously it will get torn down, but what will we do after that? Will all the rubble just go to some dump off in the middle of nowhere? Or perhaps some of the waste will be dumped in some natural place, like a stream or a lake? I think to truly be environmentally friendly we need to find good use for the old building's rubble. For example, recycling metals to be used for newer buildings (maybe even parts of our new school). For me that would sound like a very environmentally friendly school, "This partially made with recycled parts of the old buildings". Besides that I think recycling should be stressed more at the new building and we should also look into getting power from clean sources. The biggest part of being an environmentally friendly school, however, is to follow through and walk the walk.
