Glass does not pollute our environment, but its fabrication needs a lot of energy and its recycling avoids more than 500kg of CO2. Glass can also hurt humans and animals if thrown away into nature. It is important to recycle glass, as it is infinitely recyclable. If you cannot recycle, here is another solution.



Make glass sand.
