how sustainable is…
This study investigates the environmental impact of peanut butter production in the USA. It identifies the following main environmental impact categories: natural gas production, disposal of municipal waste, disposal of coal byproducts, and pesticide use.
Natural gas production and use is associated with drying (buying point) and roasting. Disposal of municipal waste was associated with blanching, roasting, and processing. Disposal of coal byproducts is associated with processes on the farm. Pesticide impacts are primarily associated with farm operations. However, interestingly, pesticide amounts reported to be used at the sheller, blancher, and roaster are in quantities large enough to be used in the model.
The study also investigates greenhouse gas emissions from peanut butter production. Although this was outside the study boundaries, it finds that the use and disposal phase cause the highest amounts of greenhouse gas emissions (for the electricity required to pump and heat the water for cleaning the dishes).
