Earth Day @ Penn Hills Charter School of Entrepreneurship

​Penn Hills Charter School of Entrepreneurship invites you to their Earth Day Celebration — and a look at what happens when students run a real circular economy.

​PHCSE students are using the ZEUS biodigester to convert cafeteria food scraps into Soil Sauce, a nutrient-rich liquid fertilizer that feeds the school gardens. The gardens grow produce. The students earn Community Credits (C¢) through involveMINT for their work — credits they can spend with local businesses across the network.

​What you'll see:

• ​The ZEUS biodigester in action (built by Ecotone Renewables)

• ​School gardens and food forest growing with student-made fertilizer

• ​Heartcore — the student enterprise behind it all

• ​How Community Credits connect school sustainability to the local economy

​This project is part of involveMINT's PHCSE Food Learning ECOconomy, supported by a Remake Learning Moonshot Grant.

​Whether you're a neighbor, educator, parent, or local business owner curious about community credit exchange — come through.
