Events produce copious amounts of waste–leftover food and drink, food wares, paper, aluminum cans, glass bottles, plastic banners and signage, cooking oil and more—but what’s often overlooked is the greywater generated from cooking, cleaning and hand-washing stations, particularly at outdoor food festivals. While food trucks are required to contain their own wastewater containers and are critical, mandatory components of their plumbing system to prevent illegal dumping, festivals with stand alone food operators have to rent their own sinks and arrange some method of containment until that greywater can be responsibly disposed.
