Pyrolysis gas to provide thermal energy for, e.g. drying processes
BioChar as an attractive product for agriculture, animal husbandry and food industry ...
Pyrolysis coal is a stable, with nutrients (e.g. phosphorus) and free of harmful substances (antibiotics, hormones, pesticides, microplastics)....
With the anticipated widespread end of agricultural utilization of sewage sludge, thermal processing of this waste material has become essential.
In this regard, pyrolysis presents a good and comparatively favorable alternative to the co- or mono-incineration. With the T:CRACKER unit, NGE offers an innovative and continuous processing technology whereby sewage sludge is recycled both as material and for energy. In addition to reducing the amount of original dry mass by approximately 50%, a sanitized (thermal destruction of xenobiotics, hormones, microplastics, etc.) of sewage sludge coke can be achieved, and can be used as a valuable phosphorous-rich soil additive, depending on the input load (primarily heavy metals).
The pyrolysis gas produced at 550°C is fed to a controlled incineration unit, in which the sewage sludge is heated and dried via a heat recovery system.
Furthermore, it is possible to add a compact Pyrolysis Coke Degassing System (PCDS) which allows the generation sewage sludge ash analog to ash derived from mono-incineration. This material can be utilized for ash-based phosphor recycling or fertilizer industry in case.
