"waste glass in municipal solid waste" refers to glass containers, tableware, window glass, and other glass products generated during residents' daily life and consumption. These glass materials, once mixed into municipal solid waste, lose their original functionality, or although not completely losing their potential for reuse, are discarded. After collection, sorting, cleaning, crushing, and melting, such waste glass can be used as recycled raw material to produce glass products, construction materials, or highway engineering materials, thereby achieving resource recovery.
