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 January 2020:
- 7,051 lbs of food waste diverted from the landfill
- 10,804 lbs (4.9 metric tons) CO2 equivalent would have otherwise been generated by the food waste itself at the landfill.
That’s around the same emissions from using 551 gallons of gasoline in a car, or 13,775 miles driven with 25mpg fuel economy.
- 304 buckets (5 gallon) and 54 bins (32 gallon) collected
Since December 2018:
- 19,335 lbs of food waste diverted from the landfill
- 29,626 lbs (13.44 metric tons) CO2 equivalent diverted
Equivalent to about 1,511 gallons of gasoline in a car, or 37,773 miles driven with 25mpg
- 1,052 buckets (5 gallon) and 66 bins (32 gallon) collected

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.
