A better use of recycled glass

For those of you that recycle their plastic bottles and aluminum cans, you know that a nice return will come back. But when you try to recycle glass bottles, they become a hassle. Most recycling centers recqure you to seperate the colors with the clears. All this hassle for a small return. Reason be is that recycling glass bottles to make new bottles is a harder process than it seems. Instead of recycling them into new bottles, a scientist in the UK has discovered a way to turn ground up glass into a special compound called "tobermorite" which sucks up toxic materials from groundwater. This is a more practical way to recycle bottles since colors would not matter.
