  • Vermicomposting in ActionRedworms (Eisenia foetidaie & Lumbricus rubellus) Live in the top 12 inches of soil Feed on organic decaying matter Can eat their body weight in food every day Generate 75% of body weight in worm poop (castings) each day Lay one cocoon every week or so Each cocoon produces 3 to 4 baby worms Begin breeding at 4 to 6 weeks of age Worms can double population every 90 days Live up to 2 years

  • Vermicomposting in ActionCompost Tea Liquid produced from vermicomposting Protects plants from disease Improves nutrient retention Decomposes harmful chemicals Transforms compacted soil into healthy soil Reduces water usage Decreases run-off and leaching

  • Composting vs. LandfillingSome Numbers to Consider Food and yard waste account for at least 25% of landfill materials AA dining halls generate 700 pounds food waste each week 12% of total greenhouse gas emissions generated from growing, preparing, and shipping food Eating 1 pound of food daily generates 1.5 tons of carbon dioxide (CO2) annually CO2 impact from edible food waste per person equates to taking 1 to 4 cars off the road CO2, methane(CH4), and nitrous oxide (N2O) generated as organic waste decays in landfills CH421 times worse and N2O 300 times worse than CO2 Proper composting minimizes greenhouse gas emissions and extends life of landfills by saving space
