Mass burn incinerators are big confinements where people use it to burn big amounts of trash. Once the trash is cleaned and separated (for recyclables), is transported to this machine which will burn it with high temperatures. Ash and particulates are vaporized into the atmosphere; and if anything remains then it is move to create different types of metals. While the machine is working, water is circulating through the walls of the machine and turbines to produce the energy necessary. If the quantity of the trash is bigger than expected, then they leave the trash in lower temperatures for a long period of time so it can burn down properly without overusing the machine.
