Regenerative Energie
Future-oriented waste management concepts should combine economic and ecological requirements. Within this context, the pyrolysis or gasification of high calorific waste fractions can, in combination with the existing or newly built power plants and industrial furnaces, offer an alternative technical solution, provided that it is mainly used for selected high calorific waste and waste fuels.
Pyrolysis and gasification technologies are generally much more valued as alternative waste treatment technologies in Europe than they are in Germany. This is especially valid for the Anglo-American regions, for which consultancies, such as the English Juniper Consultancy Services or the Frost&Sullivan, have been forecasting for decades a breakthrough of gasificationand pyrolysis technologies or at least an overall increase of both on the thermal waste treatment market. However, failed predictions, such as the one made by Juniper in summer 1997, according to which pyrolysis and gasification would grow to represent a 20 % share of the entire European thermal treatment market in 2007 (especially in Germany and France), have proven that they are of limited value. In this, what was to be a fortunate period for these technologies, the most promising technology of that kind - Thermoselect disappeared from the European market completely, as it similarly happened decades ago to the American concept Andco-Torrax. Whether possible changes in economic and political conditions could affect the development of these alternative technologies for their benefit, is debatable. Before the question on the status of pyrolysis and gasification today is answered and the technological developments of the last 40 years are revealed, a quick glance the current European legislation and the decisions of the European Court is needed. The focus is on the Industrial Emissions Directive - IED, which replaces the IPPC Directive, and on two recent court decisions that could affect the legal classification/description of pyrolysis and gasification when it comes to the incineration and co-incineration of waste. Both deal with the special situation when using gasification or pyrolysis as method for the thermal treatment which is normally covered as incineration or co-incineration of waste. But under special conditions it can be taken out of the scope of waste incineration activities which leads to less stringent emission standards. More details can be found under the described literature.

Die EEW Energy from Waste GmbH (EEW) hat sich das Ziel gesetzt, bis 2045 klimaneutral zu werden. Mit 17 Standorten verfügt EEW über eine Verbrennungskapazität von ca. 5 Millionen Tonnen Abfall pro Jahr.
Abfall- und Kreislaufwirtschaft in Deutschland im internationalen Vergleich - Spitzenplatz oder nur noch Mittelmaß?
© Witzenhausen-Institut für Abfall, Umwelt und Energie GmbH (4/2025)
Neben der Umstellung der künftigen Energieversorgung auf ein zu 100 % erneuerbares Energiesystem ist die Abfall- und Kreislaufwirtschaft die zweite zentrale Säule im Rahmen der globalen Transformation in eine klimaneutrale Wirtschaft und Gesellschaft.
