Farm Aid has partnered with St. Louis businesses to help achieve zero waste goals during the concert and add to the established Verizon Wireless Amphitheater recycling program.

With the help of Replenishing the Earth and Route 66 Organics, all compostable waste   will be turned into agricultural material. Volunteers will help concertgoers differentiate between landfill-bound trash, recyclables and compostables.

The energy used to produce the concert will be offset by purchases of renewable energy certificates through the Bonneville Environmental Foundation. Farm Aid’s concert greening initiatives are underwritten by Horizon Organic and Silk Soymilk.
