Why does reusing a glass bottle usually have a smaller impact on the environment than recycling it?
Reusing a bottle does not need the bottle to be transported
Recycling needs energy to crush and to melt the glass
Recycled glass can only be made into building materials
Reusing a bottle removes the need to wash it before use
