There are primarily four types... but essentially what you will need in everyday life is either the first or the second as most people use that.
1.Continuous-feed Disposals – Placed under a sink. Efficient and quick grinding.
2.Batch-Feed Disposals – Simpler installation and safer than continuous-feed disposals.
3.Dishwasher Garbage Disposals – Only for food particles and can also be found inside the dishwasher unit
4.Septic Tank Garbage Disposals – Only for septic tanks. There is a special feature to break down food scraps.
