When we throw food away, we remove important nourishment from the soil nutrient cycle that can be used to grow food and support biodiversity. But food waste in landfills also generates greenhouse gas emissions. In a landfill, food waste undergoes anaerobic decomposition (without oxygen) and generates methane—a far more potent greenhouse gas than carbon dioxide (CO2). In contrast, most home and garden composting is aerobic (with oxygen) and, when done correctly, virtually eliminates methane emissions. Aerobic composting also stores carbon in the soil.
We collect food waste from:
- Flagstaff CSA & Local Market Community compost drop-off
- White Dove Coffee
- Potion Tea & Bakery
- Canyon REO
- Pine Forest School
- Laura Chamberlin Professional Chef
- Sugar Mamas Bakery
- Flagstaff-area residential households
If you’d like to partner for compost pickup, please contact us for details. You’ll save space in your trash bins, reduce trips to the landfill, decrease your carbon footprint, and help us build fertile and resilient soil.
2021 Totals (thus far)
- 8,605 pounds of food waste diverted from the landfill
- 276 buckets (5-gallon) and 70 bins (32-gallon) collected
- 13,185 pounds (5.98 metric tons) CO2 equivalent would have otherwise been generated by the food waste at the landfill.
That’s about the same emissions from using 672 gallons of gasoline in a car, or 16,800 miles driven with 25mpg fuel economy.
- 22,625 pounds of food waste diverted from the landfill
- 785 buckets (5-gallon) and 179 bins (32-gallon) collected
- 34,666 pounds (15.72 metric tons) CO2 equivalent would have otherwise been generated by the food waste at the landfill.
That’s about the same emissions from using 1,768 gallons of gasoline in a car, or 44,200 miles driven with 25mpg fuel economy.
All-Time Totals (Dec 2018 – present)
- 43,513 pounds of food waste diverted from the landfill
- 1,809 buckets (5-gallon) and 261 bins (32-gallon) collected
- 66,672 pounds (30.24 metric tons) CO2 equivalent diverted
Equivalent to about 3,400 gallons of gasoline in a car, or 85,007 miles driven with 25mpg

Notes: Carbon dioxide (CO2) equivalent is a quantity referring to the conversion of different greenhouse gases’ warming effects into common “units” of carbon dioxide’s warming effect. For example, methane has a warming effect of up to 34 times more potent than CO2 over a century, so every 1 pound of methane emissions is 34 pounds of CO2 equivalent. Food waste emissions calculations derived from the EPA’s Waste Reduction Model (WARM) and Greenhouse Gas Equivalencies Calculator. The EPA’s WARM calculations are tailored to waste management entities and don’t account for our small vehicle’s transportation emissions.
