Pyrolysis of Sewage Sludge: Physical, Chemical, Morphological and Mineralogical Transformations
Jóisman Fachini, Cícero Célio de Figueiredo
Abstract
HIGHLIGHTS Biochar from sewage sludge (SS) was produced and characterized. Pyrolysis increased organic and total carbon. Pyrolysis increased micro and macronutrients concentration with exception of K. Biochar preserved the mineralogical characteristics of the raw material. Pyrolysis is an excellent alternative to transform SS into organic fertilizer.
