Morton Arboretum's pathway is made of recycled beer bottles

Putting discarded beer bottles to a better use, the Morton Arboretum in Lisle utilized these to make a 1,440-square-foot pathway leading to arboretum’s Thornhill Education Center. Dubbed as the FilterPaveTM, the pavement is made of crushed beer bottles, other glass and granite fragments, held together by a special mixture of polyurethane. The glass has undergone thorough processing to round its edges. The manufacturer, Presto Geosystems of Wisconsin, states that the porous pavement costs about $10 to $12 per square foot installed.

The trials have testified such porous pavements to last 16 years without needing any repairs. Since fast-moving rainwater leaches through these pavement, the porous surface doesn’t add pollutants to nearby water sources. Moreover, it reduces the "heat island" effect by trapping heat and not allowing it to reflect into the atmosphere.
