For an alkali pyrolysis, the sewage sludge is pyrolysed after adding potassium. Thus, heavy metals are removed in the vapour phase. This results in a P-K fertilizer that can be fully absorbed by plants and that has a market-grade nutrient content. In this project, the process will be optimised and piloted on a larger scale. Further plans are the assessment of the agronomic efficiency, plant design, cost calculation and the draft of a sales concept.
