Microwave treatment units can be either on-site installations or mobile treatment vehicles. The processing usually includes front-end shredding of the waste, both to increase the efficacy of the microwave treatment and to reduce the volume of the end waste for disposal. If the waste is dry, water is introduced and the wet waste is introduced to the microwave chamber<ref name="Mals">[https://www.malsparo.com/treat2.htm/ Malsparo]</ref>. Typical operation is at 2450 Hz. Microwave power causes the temperature of the water to increase. If an [[Autoclaving|autoclave]] provides heat from outside the waste, the microwave unit transmits energy as microwaves and that energy turns into heat inside the wet waste<ref name="Mals" />. | Microwave treatment units can be either on-site installations or mobile treatment vehicles.

Microwave disinfection works only when there is water in the waste because the radiation directly works on the water, not the solid components of the waste<ref name="Mals" />. For this reason, treatment units are often supplied with a humidifier. Processing time is in the region of 20 minutes per batch<ref name="Mals" />. | Microwave disinfection works only when there is water in the waste because the radiation directly works on the water, not the solid components of the waste<ref name="Mals" />.

With enough power the water is converted to steam and makes all of the waste around 100 degrees C. The entire process takes place within a single vessel<ref name="Mals" />. | ||
