“What is a zoo to do with its excess panda poo? Denver’s answer is to compress it into pucks and feed them to a syngas-powered hybrid-electric Tuk Tuk.
As anyone who’s been to a zoo can attest, those animals truly enjoy a good deuce. They do it constantly, typically producing more waste than the facility can reuse. Zoo’s often have to haul the excrement away for disposal in landfills—an expensive and inefficient option. But the Denver Zoo has spent nearly a decade working on an ingenious and local alternative to landfills—a 20-year-old motorized rickshaw, also known as a Tuk Tuk.”
Ingenuity can always think of a productive use for our waste.
