Glassware Special Instructions Glassware goes in either the gray landfill cart or the blue recycling cart – based on what type of glass it’s made of. If the item is borosilicate (tempered) glass, crystal, pyrex, or other dishware, it needs to go in the gray landfill cart. If the item is a standard glass jar or regular drinking glass, it can go in your blue recycling cart. Different Glass, Different Instructions If an Item is made of tempered (borosilicate) glass, crystal, pyrex, or other dishware, it belongs in the garbage. It cannot be recycled with glass bottles and jars. Its melting temperature is different, so it can contaminate an entire batch of recycled glass. If the item is a standard glass jar or regular drinking glass, it can go in your blue recycling cart. Ways to Reduce Buy Used or Vintage Glassware Glassware can last decades. Buying used glassware reduces the need to manufacture new glassware. Simply avoid items made before 1971, which may contain lead. Don't Want Your Glassware? Donate It If you don’t want your glassware anymore, consider selling it, donating it or giving it away.
