Glass is made from sand, an invaluable yet finite resource harvested from nature. To make new glass, we would have to continue harvesting from the increasingly fragile landscapes on Earth.
As one of the most consumed natural resource, we may also face a sand crisis in the near future
(Torres et al., 2017). But being so heavy and challenging to process, glass is less of a priority in any recycling programme.
By choosing to upcycle and recycle glass, we help to circulate existing glass within our economy and society. This reduces damage to nature amidst our hunger for ever more resources.
