It depends on which aspects of the environmental impact you’re looking at, as melting glass to recycle it can be much more damaging than landfilling several plastic bottles if the glass furnace is heated by fossil fuels. If glass bottles are washed and reused, they’re much better than plastic, but that’s rarely what happens.
Gas is used to heat up glass furnaces most of the time. But it is possible to use elctricity aswell, which is more and more sources from either solar or nuclear.
Not saying it is greener than plastic when it comes to electricity and shipping.
