Can You Incinerate Medical Waste?

1 23
Incineration of medical waste is possible, and it involves burning unwanted materials produced by research facilities, veterinary facilities, and hospitals. These by-products include infectious and non-infectious wastes.
There are three types of medical incinerators used: rotary kiln, excess air, and controlled air.

Rotary Kiln

A Rotary Kiln burner has a central chamber, where waste materials are heated and vaporized. It also has another compartment, where volatilization is completed.

The main chamber has a rotating kiln that is inclined. It is where waste transfers from the feed segment to the ash discharge segment. The combustion air goes into the main chamber with the use of an auxiliary heater.

Excess Air

An Excess Air burner is typically a smaller unit. Also known as a retort incinerator, multiple compartment incinerator, or batch incinerator.

This type of incinerator consists of a dense cube with many baffles and internal compartments. Although it can function continuously, it is typically operated in batches.


A Controlled-air Incinerator is an MWI (Medical Waste Incinerator) that is most commonly used globally.

The process is referred to as modular combustion, starved-air incineration, or two-stage incineration. Combustion of by-products in this type of incinerator undergoes two stages.

First, medical waste enters the combustion chamber. Inside the combustion chamber, the air stimulates the evaporation of trash and the burning of residual carbon.

Excess air will then be supplemented to the evaporative gases in the main compartment to achieve complete combustion.

Facilities use incineration to lessen the amount of solid waste, minimize the volume and potential infectious effects of medical waste, and reduce the volume and potential toxicity of biological and chemical waste.
