Garbage disposals have an upper and a lower chamber, separated by metal shredders. Once shredded, food waste flows easily through your plumbing.
The biggest issues are jams and clogs. Avoid putting in hard or fibrous foods, such as husks and bones. Or gummy or expanding foods, such as banana peels and pasta. Never put your hands in the disposal.
