What is vermicomposting???

• The process of composting with worms.

Page 3: Vermicomposting in the home

Why compost? • Last year we threw away about 133 billion

pounds of food.

• At least 12% of municipal waste is food.

• Spend $1 billion to dispose of food waste

• The average American throws away 209-245lbs of food per year.

• If we wasted 5% less each year we could feed 4,000,000 Americans.

• Landfills account for about 1/3 of all methane emissions in the air.

already added before adding more.
