Food waste typically winds up in a landfill, contributing to methane emissions and creating water quality concerns. Instead, a startup company uses an aerobic digestion process to break down the organic matter obtained from grocery stores into a liquid fertilizer.
The company believes their fertilizer stimulates additional root growth and allows plants to better absorb nutrients.
Lewis is studying the fertilizer’s impact on crop yields, soil health, and water quality. Last year, he conducted field trials on various crops. While the results have not been peer reviewed, the fertilizer does appear to improve crop yield.
“We did about 40 trials,” he said. “In most of them there was some improvement.”
