Two teachers at the 4th Primary School of Nea Smyrni in Greece are responsible for overseeing the school's composting procedure. Students voluntarily participate in separating paper, plastic, and other recyclable materials like batteries and lamps into designated recycling bins. As part of their recycling and composting education, students watch instructional videos, complete worksheets, and discuss related topics. The teachers have a monthly plan for maintaining the proper balance of water, greens, and browns needed for effective compost development.
