(September 21, 2017) Keep Pennsylvania Beautiful invites schools in Pennsylvania to participate in their Litter Free School Zone Program, a comprehensive program that encourages young people to play an active role in protecting and improving our environment through recycling, litter awareness, and community stewardship. Keep Pennsylvania Beautiful provides a sign recognizing the participating school as a Litter Free School Zone. The school, in turn, organizes two cleanup or beautification events per year. There are currently over seventy schools that participate in the program. All schools are welcome – elementary through high school.
