HPS visits Princeton University

HPS visits Princeton University

On March 7, our 12th grade Global Issues classes visited Princeton University to learn about their latest sustainable innovation, an aerobic biodigester!

Biodigester systems work by taking advantage of natural biological processes through a closed system. As waste is broken down, microbes release methane, carbon dioxide, and other gases. The system captures and stores gases to use as a valuable energy sources.

According to the EPA, diverting 50% of food waste from landfills and capturing the methane could provide enough electricity to power 2.5 million homes. Also, the solid and liquid residue that remains at the end of the biological process is nutrient-rich, and can be used as either fertilizer or compost, depending on the raw materials used.

Many thanks to Princeton University for their hospitality!
