A 40-seat airport shuttle bus in Britain is making headlines for running on human sewage and food waste.

The Bath Bus Company's Bio-Bus hits the road next week moving passengers between Bristol to Bath while cutting its emissions by 30 percent with the use of biomethane gas instead of diesel fuel.

The odorless gas is produced at a sewage treatment plant in Avonmouth run by GENeco, a subsidiary of Wessex Water, reports the BBC.

In the US, the Sanitation District of Los Angeles is converting its trucks to use biogas being processed as its landfills. It also sells the alternative fuel to anyone with a compressed natural gas vehicle in Carson and Puente Hills. Learn more about related services in California, from the California NGV Coalition.
