    • Composting at Whately Elementary School Bill Obear, Bear Path Farm Presentation by: Ms. Amy Donovan, Program Director
    • What is Compost?
      • In nature, soil organisms called decomposers eat p lants, leaves, and dead animals.
      • The end result is soil, or compost .
      • That compost then nurtures new plants to grow.
    • What is Compost? Composting uses that natural cycle to dispose of food waste, making soil in the process.
      • Compost is good for plants:
      • adds nutrients to soil
      • reduces need to water
      • replaces chemical fertilizers
      • used on farms for growing vegetables
      • in home gardens for growing flowers, vegetables
      • in landscaping
      Farmland Finished compost
    • Composting keeps food out of landfills (dumps).
      • Composting saves space in landfills.
      • Our local landfills are almost full!
      • Where will be put our trash in the future?
    • Composting helps slow Climate Change Climate Change (or Global Warming) is caused by greenhouse gases in our atmosphere. Greenhouse Gases : Carbon Dioxide Methane Nitrous Oxide
    • The Climate Change Connection
      • When food waste (and paper) decay in a landfill, methane is released.
      • Methane is a greenhouse gas 23 times more powerful than carbon dioxide.
      • Over 20 years, methane from a landfill can be 72 times more potent than carbon dioxide!!

    • Why doesn’t composting release methane? Because oxygen is part of the composting process. There is no oxygen in a landfill. Compost bins made from reused pallets
    • 3 “sizes” of composting:
      • Small : An indoor worm bin uses red wiggler worms to eat food waste (vermicomposting)
      • Veggies, fruits only
      • Medium : Backyard composting
      • Veggies, fruit, bread
      • No meat, dairy, oils
      • 5 th grade class has this type of bin.
    • Large : Commercial Composting at Bear Path Farm in Whately. Accepts all food: meat, cheese, oils… Paper: napkins, straw wrappers… Windrows at Bear Path Farm

    • How does it work? A compost bin needs:
      • Water: material in bin should be as damp as a wrung out sponge. Add water if not, and when building pile. Add sparingly in winter.
      • Air/ Oxygen: mix/stir occasionally
      • “ Green” materials: (nitrogen) food waste
      • “ Brown” materials: (carbon) leaves, hay, shredded and soaked newspaper, egg cartons
      • Microorganisms: eat material and heat it up
    • Food Web Of the Compost Pile
    • Keep it cookin’
      • Each time you add food waste, bury in center and cover with leaves/ brown materials
      • Add leaves or brown materials regularly
      • Add water regularly
      • Stir entire pile every 6 weeks or so.
      • Once you have a bin full of materials (in 6-12 months), stop adding materials and stir more frequently.
      • When the compost is finished, use on gardens and when planting new plants
