Waste superheated steam decomposition technology is an emerging harmless treatment method. It is a technological upgrade based on subcritical hydrolysis technology. Similar in principle to subcritical hydrolysis, it modifies the thermal decomposition conditions by reducing the production pressure (to 0.02-0.3 MPa) and increasing the decomposition temperature to between 300-800°C (the temperature is typically higher than the supercritical temperature point, while the working pressure is much lower than the subcritical pressure). In an oxygen-free or low-oxygen environment, organic waste undergoes thermochemical decomposition using high-temperature superheated steam (typically 300-800°C, pressure 0.02-0.3 MPa) as the heat carrier and reaction medium. In superheated steam decomposition technology, temperature and pressure are inversely proportional; for example, low pressure requires high temperature, and low temperature requires high pressure. This process promotes the thermochemical decomposition of organic matter in domestic waste. The products generated are the same as those from subcritical hydrolysis: organic matter can be thermally decomposed into reusable resources such as combustible gas, water, carbon dioxide, organic coal, and fertilizers. Simultaneously, harmful substances are also decomposed into harmless byproducts, thus achieving the resource utilization of waste.

Superheated steam decomposition technology enables the efficient and clean continuous conversion and decomposition of organic waste by using low-pressure, high-temperature heating steam. Because it can be carried out under atmospheric pressure, its safety and stability are very high.
