> Most glass is mostly sand, an abundant raw material.
Sand is not actually an abundant raw material [0]. Although sand in general is abundant, sand that is usable for construction and manufacturing is generally found on beaches and flood-plains - desert sand is less angular and usable. We extract 50 billion tonnes of sand per year and this is getting worse as a result of continued massive urbanisation. Ocean dredging for sand has significant ecological input.
This might not be why glass recycling started, but it suggests an incentive for continuing to do so.
