Abstract This study used material flow analysis and scenario analysis to explore the flow and sustainability of glass resources from 1949 to 2050. The results show that waste domestic glass and waste glass fiber are the key nodes of resource loss. Under different demand growth rates, the primary resource demand will exceed the current resource reserves in some period from 2030 to 2050. By 2045, it is expected to increase the recovery rate of waste flat glass to 70% and the recovery rate of waste domestic glass to 60%, so that glass silicon resources can meet the low growth demand. In order to achieve the recycling goal, the government should continue to promote waste classification, encourage enterprises to extend the life of glass products from the design end, improve recycling technology, and establish a good recycling system.
