Abstract: A waste chute for a multistory building is made up of modules stacked one upon the other. Each module has a vertical section of waste chute enclosed within a fire safe room. The chute sections are arranged to nest together to form a continuous chute when the modules are positioned on one another. Each room is provided with a door providing access to the room. The chute section is provided with a self closing access door. An alternative embodiment of the invention provided a module for more than one story. The multistory module has a room for each story. By integrating the chute section with the chute room in a prefabricated module, the construction of a building is facilitated. The costs and complications of having multiple trades working on the chute system are avoided. The invention may be practiced with a system for collecting different types of trash in different receptacles beneath the chute. Prewired controls in the module at each chute access door select the receptacle beneath the chute.
