  • 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!!
    Methane pipe at a landfill
  • 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

    • 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
