Eco-friendly hot cups are made from renewable resources to reduce your environmental impact. Disposable material makes cleanup fast and simple after each use. Smooth rolled rim enhances the cup's strength and ensures a secure lid fit. Instead of a polyethylene lining to prevent condensation and leaking, these cups are lined with PLA (poly-lactic acid), a renewable resource, which is compostable and derived entirely from plants. These cups are ASTM D6868-11 compliant and BPI certified. They can be paired with versatile Genuine Joe lids (10212 - sold separately) that also fit Genuine Joe 12 oz. cups for a more efficient beverage center.Eco-friendly hot cups are made from renewable resources to reduce your environmental impact.
