The school wanted to reduce waste and teach students about the environment. Teachers and students worked together to make the school greener. First, the school placed recycling bins in every classroom. Students learned how to separate paper, plastic and glass. They also started a food waste programme, collecting leftover food to make compost for the school garden. The project has been a great success. The school has recycled over 500 kilograms of paper and plastic. The garden has produced many vegetables that are used in the school kitchen. Students have become more aware of environmental issues.
