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.
Since December 2018, we’ve diverted 12,916.8 lbs of food waste from the landfill, collected in 786 buckets (5 gallon) and 13 bins (32 gallon).
At the landfill, this food waste would have otherwise generated about 19,791.3 lbs (8.98 metric tons) CO2 equivalent. That’s around the same emissions from using 1009 gallons of gasoline in a car—or 25,225 miles driven with 25mpg fuel economy.

We collect food waste from:
- White Dove Coffee
- Potion Tea & Bakery
- Canyon REO
- Late for the Train‘s roastery headquarters
- Pine Forest School
- Deana’s Cocina
- Single Speed Coffee Roasters
- a number of residential households
If you’d like to partner for compost pickup, please contact us for details. You’ll save space in your trash can, reduce trips to the landfill, and help us build fertile and resilient soil.
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.
