Will this be the coolest—and quietest—garbage truck in the world? Perhaps—but we’ll believe it when we actually see it. Nikola, whose most notable contribution to the pickup-truck world thus far is the hydrogen fuel-cell Nikola Badger, is now dabbling in the dirty business of trash collection with its Nikola Refuse battery-electric garbage truck. Nikola, which is shooting for dominance in the zero-emissions heavy truck market, sees waste as a stable business and has received an order of 2,500 electrified Nikola Refuse trash trucks from Republic Services, the second largest recycling and solid waste provider in the U.S. The order is expandable up to 5,000.
