Closing the Loop: Fueling Trucks with the Organic Waste They Pick Up

When you placed your food waste at the curb last time, did you consider the journey it’s about to take? You could find it coming back down your street the next month as the fuel in the truck that picks up that week’s organic waste. That’s closer to Doc’s “flux capacitor” from the 1985 movie Back to the Future than most people ever imagined – and the fuel is powering trucks on American roads and around the world right now.

Biogas, or natural gas from organic sources, has been used for decades and was recognized as a renewable source for electricity. In the intervening years, natural gas fuel stations and the natural gas vehicle base has expanded, opening up the market for renewable natural gas (RNG) use in transportation.

Refuse operations across North America are embracing the opportunity to fuel trucks with the very waste they pick up. The RNG created with processed organic matter such as food scraps (or in other cases landfill gas) can power trucks equipped with a natural gas engine such as Cummins Westport ISX 12G or ISL G engines.

In North America, fleets and energy partnerships from Georgia to Quebec to California are embracing the concept, saving waste and money in the process. The vehicles operating on RNG from organic sources include refuse or sanitation trucks, pickup trucks, utility vehicles, and tractors.
