You no longer have to cut down a forest to build a gleaming parquet floor. In fact, some of the most popular new materials aren't made of wood at all. A look at some environmentally sound options:
Cork: Usually taken from a bottling company's leftovers, it's softer underfoot than hardwood (from $6.50 per square foot; greenfloors.com ).
Recycled glass: It's more slippery than ceramic, so use the smallest, one-inch tiles for your bathroom (about $30 per square foot; sandhillind.com ).
Renewable rugs: Flor ( florcatalog.com ) is one of a growing number of companies offering partially recycled, adhesive-free rugs (from $6.50 per square foot).
