One cannot appreciate how food processing wastes become biofuels just by reading about it in a book.
Students in science teacher Melanie Bachart’s high school bioethics course at Chiawana High School, Pasco, Washington, got the full experience of producing carbon-neutral biogas from food waste that usually winds up in landfills. Biogas can be used in place of natural gas to power electrical generators or to provide heat for industrial processes. It can also be used to power cars and trucks that are equipped to run on compressed natural gas.
It was a tactile, memorable experience for the students. Their adjunct instructors for the project were Pacific Northwest National Laboratory (PNNL) researchers, representing PNNL’s Science, Technology, Engineering, and Math (STEM) program.
