I like the idea of garbage disposals but you wouldn’t really control.
Grease and Fats may liquefy and then solidify further down the water pipe which usually could clog up the drain.
It seems to me a great idea, on the one hand food trucks (restorers + passenger airplanes) could come from the other supply trucks (shops), from the other construction materials (constructions + object repairs). And trucks, however, apart. And cooking the food you get will be great.
It is a great idea and could be implemented with the catering service.
