(You can see visual evidence of a Square Burger Cake Shake in a Greenware cup in this photo by Unbreaded.)
About the cups:
The Fabri-Kal Greenware line is made from NatureWorks biopolymer, a polylactic acid (PLA) resin derived entirely from plants instead of oil. All Greenware products are created from domestically grown renewable resources and are manufactured in the U.S.A.The Phillies were supposed to sell ALL their draft beer in these cups at Citizens Bank Park. However, that still has not happened.
Greenware products break down into carbon and water, like other matter derived from plants, in properly managed composting facilities with mature compost, constant temperature control and specific relative humidity for good biological growth. Correctly done at 150F and 90% humidity, products will completely compost in approximately 50 days.
So we are happy to see Stephen Starr taking steps to make Square Burger at least somewhat environmentally responsible.
It is located in a park, after all.
