Pyrex Landfill (Trash) Cart Is your Pyrex still in usable condition? Donate it! Visit our Donation Locations page for more information. Do Not Recycle Pyrex cannot be recycled because it melts at a higher temperature than glass bottles and jars. It will contaminate a batch of glass recycling. Wrap up Pyrex before throwing it in the garbage. Ways to Reuse Good Condition? Donate It Pyrex can last a long time. If you have Pyrex that’s still in good condition (i.e., no cracks or chips in the glass), don’t throw it away. Give it away or donate it to a thrift shop.
