What is Waste?
• There is no waste in nature.
– Everything is FOOD for something else
– In sustainable practices, leftovers from one
process become either compost or feedstock for
another. See Bill McDonough ‘Cradle to Cradle’
Northpoint Press 2002
• Waste = resources out of place.
• Waste is evidence of inefficient processes.
• It’s not garbage until we throw it away.

• Good for the economy
– 17,000 recycling related jobs in North Carolina
• Provide re-manufacturers with feedstock
• Purchasing products made from recycled
materials supports recycling markets and
businesses in North Carolina and beyond
Look for this symbol on
products with recycled content.
Always ask for recycled

“My kids figured out that we waste
approximately 10 tons of milk each year, to
the tune of around $23000 (based on the
13 gallons that were tossed on our
collection day). They were shocked, to say
the least, and are trying to figure out how to
best spread the word.”
Kristin Bedell
Efland-Cheeks Science Teacher
Why Compost? • Reduce air, water and soil pollution.
• Reduce reliance on landfills.– 30% of what we throw away is food waste
• It’s a great teaching tool for biology, ecosystems, chemistry and math!
