Shedd says it is committed to meeting three goals by 2021. They are to significantly reduce or eliminate single-use plastic packaging in retail products, reduce single-use plastic in “back-of-house” operations, and eliminate single-use plastic in all dining tableware.

ACP aquariums have already eliminated plastic straws and single-use plastic take-away bags. They are working to reduce plastic beverage bottles by 2020.
