It may come as a surprise, but food trucks are inherently less wasteful than traditional restaurants in many ways. Once they arrive at their destination, they use only a fraction of the utilities that larger brick and mortar restaurants use. Food trucks must also contend with unique challenges, such as limited space for food and supplies (including water) forcing them to conserve as much as they can and making them highly aware of waste. When it comes to overall emissions, there doesn’t appear to be a definitive answer as to which setup comes out ahead.
