It is inefficient and unsustainable to haul human waste back in from remote festivals and other places typically populated with port-a-potties. So why not use on-hand materials to make something simple and green?
Thus L’Uritonnoir by Faltazi which turns an everyday farm item into a urinal by means of simple funnels attached on various sides and connected via a loop running around the perimeter. The composted results can be recycled right back into the local land.
“An uritonnoir is a hybridisation of two everyday products, an urinal and a funnel (literally in french, “urinnoir” et “entonnoir”). This system is used either used in public spaces during festive events (slotted into round bales) or in private gardens (slotted into small straw bundles). L’Uritonnoir is an utensil filling a volume of straw (carbon) with urine (nitrogen) in order to compost it during a 6-12 month period and convert it into humus.”
The flat-pack design makes it easy to transport and deploy then clean or discard, minimizing waste and transit costs and making for easy assembly at events. A stainless-steel alternative is less portable but easier to clean and reuse. “The round bale stays and composts on-the-spot. Six months later the manure can be used by local farmers. The following year, it can be used as a giant planter to be enjoyed by new festival-goers !”
