The main components of the glass bottle are silicon dioxide, calcium silicate and sodium silicate, etc., with very stable chemical properties. Waste glass products are difficult to decompose in the natural environment and cannot be degraded in landfills. In addition, glass is a non-combustible substance. Once it enters the waste incinerator, it will soften and adhere to the furnace wall, affecting the incineration efficiency. So the best way to dispose of waste glass bottles is crushing and recycling. There are many uses for recycling waste glass, such as glass raw materials, paint raw materials, building tiles, glass mosaics, glass tiles, production of thermal insulation, sound insulation materials, etc.
