RTO technology and RCO technology are VOCs (Volatile Organic Compounds) treatment technologies. They are mature technologies currently widely used, featuring excellent treatment efficiency, stable operation, and relatively low costs.

RTO refers to Regenerative Thermal Oxidation technology, with its English name being "Regenerative Thermal Oxidizer". The heat recovery of RTO (Regenerative Thermal Oxidation) adopts a new unsteady-state heat transfer method. Its principle is to heat organic waste gas to above 760°C, so that the VOCs in the waste gas are oxidized and decomposed into CO₂ (carbon dioxide) and H₂O (water). The high-temperature gas generated by oxidation flows through a specially designed ceramic heat accumulator, heating up the ceramic body to "store heat". This stored heat is used to preheat the subsequent incoming organic waste gas, thereby saving the fuel consumption required for heating the waste gas. The decomposition efficiency of RTO technology ranges from 95% to 99%.

RCO refers to Regenerative Catalytic Oxidation technology, with its English name being "Regenerative Catalytic Oxidizer" (Note: The original text has a typo "Oxidition", which is corrected to the standard term "Oxidizer" here). The working principle of RCO (Regenerative Catalytic Oxidation) is as follows: The first step is the adsorption of VOC molecules by the catalyst, which increases the concentration of reactants; the second step is the catalytic oxidation stage, which reduces the activation energy of the reaction and improves the reaction rate. With the help of the catalyst, organic waste gas can undergo oxygen-free combustion at a relatively low ignition temperature, decomposing into CO₂ and H₂O and releasing a large amount of heat. Compared with direct combustion, it has the characteristics of low ignition temperature and low energy consumption. In some cases, no external heat supply is needed after reaching the ignition temperature, and the reaction temperature ranges from 250°C to 400°C.
