Highlands even goes so far as to recycle the un-recyclable. Through an innovative company called TerraCycle, Highlands helps turn things that would otherwise be filling up landfills–like potato chip bags and juice boxes–into new items like fences, benches and recycling bins. Clever, huh? Some dedicated Highlands students even volunteer their recess time to collect accepted materials for TerraCycle from other classrooms.    Inside of the school, motion detectors for lights have been installed to reduce wasted energy.
