Using Pyrolysis Gas to Reduce CO2 EmissionsCalcination equipment requires large quantities of oil or other fuels. Although carbonization using conventional equipment generates pyrolysis gas as a by-product, up to now energy has not been efficiently recovered from this process. Our facility combines calcination and carbonization, allowing pyrolysis gas from carbonization to serve as fuel for calcination and achieving maximum energy recovery efficiency. Energy recovered from waste wood can be considered carbon neutral, and it contributes to lower CO2 emissions. Also, the fact that the energy needed for carbonization comes from waste heat means that this process uses zero fuel. Carbonization products find use as soil improvement additives and other high added value products. In addition, the warm air generated by an air heat exchanger is used effectively – for example to prevent white smoke formation – making this a highly energy-efficient system.

Electricity Generation and CO2 Emissions Reduction from Waste Heat UseHeat energy generated during incineration and calcination is converted to electric power by a waste heat recovery boiler and steam turbine. All the electricity produced is used to supply power on our site, helping to reduce our plant’s energy consumption.
