Simulation of Drying and Disinfection Technology Using Microwave Energy

Microwaves are electromagnetic waves with frequencies spanning approximately 300 MHz to 300 GHz, corresponding to wavelengths ranging from 1 to 0.001 meters. These invisible waves of energy propagate at the speed of light, approximately $3 \times 10^{8} \mathrm{~m} / \mathrm{s}$. In the electromagnetic spectrum, microwaves are positioned between radio frequencies and infrared radiation. Among the extensive range of microwave frequencies, several are specifically designated for industrial, scientific, and medical applications. Microwave disinfection is, in essence, a steam-based process, as disinfection takes place after heating the wet waste through the action of moist heat and steam generated by microwave energy. The factors influencing the microwave treatment of waste are: the frequency and wavelength of the irradiation, the duration of the exposure, the degree of destruction and the humidity of the waste and the temperature during the treatment. Microwaves interact directly with the combined plastic and paper waste to be treated. This interaction is related to the chemical properties of the material in question, and the material will be heated in a uniform, homogeneous manner throughout its volume, which cannot be achieved by any other conventional heating method.
