The RBC hosted two battery collections Sept. 8-9 in Milwaukee, including one at Rock the Green, a music festival focused on educating the community about zero waste and other sustainability activities. Participants in the collection received a discount on the ticket price for the festival that featured two stages with musical acts from around the country.The RBC was proud to be a sponsor of Rock the Green’s Pedal Power Stage. The power supplied to the stage was provided by teams of 10 cyclists pedaling on stationary bikes. Members of local cyclist clubs volunteered their efforts to keep the stage powered into the night.
