Glassware Special Instructions Glassware needs to be put into either the black landfill cart or the blue recycling cart – based on what it is. If the item is borosilicate (tempered) glass, crystal, pyrex, and other dishware it needs to be disposed of in the black landfill cart. If the item is a standard glass jar or regular drinking glass, it can go into your blue recycling cart. Do Not Mix With Glass Recycling Glassware cannot be recycled with glass bottles and jars. Its melting temperature is different, so it can contaminate an entire batch of recycled glass.
