The most common question we encounter in our practice, is the comparison of waste-to-energy technologies: gasification and incineration. While the incineration is the most prevalent and approved technology in the world, many clients are interested in gasification in hope to have cleaner and cheaper waste-to-energy plant. In our article “Why incineration?” we showed benefits of incineration, from practical, and technical side. And nothing has changed from the time of publication of the aforementioned article.
But what about economy efficiency? Maybe here gasification plant has an advantage?
We had our opinion for a long time, and recently we encountered a professional report on it by KTH School of Industrial Engineering and Management, Stockholm. This report fully confirms our knowledge of the situation. The study considers 3 cases: incineration (i), gasification with steam turbine (s), gasification with combined cycle (cc):
