Broken Glass
Instructions
Broken glass can't be recycled because it would be too dangerous for recycling station operators.
Alternatives
Consider making a mosaic; glass has a lifespan exceeding plastics.
Facts
Most non-bottling glass is made at high heat, or further laminated or layered in the case of plate and safety glass. This makes it incompatible with the various color grades of glass used for nonheated beverage and food storage, which are recyclable.
