Abstract: A waste disposal chute assembly is disclosed for segregating waste material in a multi-story building. The chute assembly has a plurality of laterally adjacent chutes, which may be nested together. Each chute has a plurality of elongate, longitudinal, telescoping members. The telescoping members have an inlet port, an outlet port and a telescoping portion. Seam cleats are provided to facilitate the unobstructed telescoping of the telescoping members into those below. Laterally adjacent telescoping members are attached and each chute has an opening to provide access thereto. Each opening may be covered by a door which is adapted to provide access to more than one opening. The chute assembly is retained in the multi-story structure.
