 Are
waste reduction efforts like recycling already in full swing at your school?
Try tackling a different green challenge by joining the world of composting.
Much of the waste in your classroom garbage bin can be composted, which
means less waste going to landfills. Yahoo! What is composting anyway? It's the natural breakdown of organic material. Huh? Basically, this means gathering in a bin items like dry leaves and grass, known as browns. Next, you mix in your sometimes icky leftovers, known as greens, like veggies and fruit peelings; stir and water contents; wait for natural processes to take place; and PRESTO you've helped turn "waste" into nutrient-rich compost that can be reused for gardening. Read on for more details. COMPOSTING AT SCHOOL: A STEP-BY-STEP GUIDE Step 1 - FIND A TEAM LEADER to guide your efforts, e.g., a teacher, a member of the maintenance staff, or a parent.  Step
2 - FORM A TEAM, A TEAM NAME AND A SCHEDULE. The schedule
serves to identify those who are responsible for weekly composting duties.
Students can take turns doing different tasks.Step 3 - GATHER SUPPLIES. For example, a compost bin, a bucket with lid, a shovel, a watering can, and gloves will get you started. Step 4 - SELECT A LOCATION. With help from your team leader, find a convenient, partially sheltered area for the compost bin. Step 5 - GATHER YOUR COMPOST MATERIALS in a small bucket with a lid. Greens are typically moist, fresh items like coffee grounds, flowers, fruits/vegetables and peelings.  Browns
are often dry items such as dry leaves and grass, coffee filters, newspapers,
pine needles, tea bags, woodchips, and straw.**Remember to collect cafeteria waste, and never put meat, fish, eggs, milk products, fatty food, animal waste or diseased plants in your compost bin. Step 6 - EMPTY THE MATERIALS INTO YOUR COMPOST BIN. Start with about 6 inches of browns, then layer greens then browns, keeping each layer no larger than about 6 inches deep. A little soil between layers helps the materials breakdown and decompose. Step 7 - ADD WATER. Keep the contents of the compost bin moist, never wet. Step 8 - TURN THE CONTENTS OF THE COMPOST BIN. Once a week, use a shovel to turn materials in the bin. This will allow air (oxygen) to circulate and aid in the breakdown of materials. Step 9 - BE PATIENT. With the proper ingredients, the compost materials will heat up (60-70 °C) and begin to decompose. Regular turning of the compost allows the ingredients to interact and heat again. Once the compost materials stop heating up as much, your compost should be ready. This may take a few months.  Step
10 - ENJOY THE END PRODUCT. When the contents of the
bin no longer heat up, are dark, crumbly and earthy smelling, you've done
your work. You now have COMPOST! The trees, flowers and plants around
your school will no doubt benefit from the addition of a healthy dose
of compost. Remember: composting is nature's way of recycling!Take Action! Start simple,
work safely,
and make your commitment strong. |
