Rosa Arranz, José M. de la Kern, Jürgen Reza, M.T. Knicker, Heike Ministerio de Economía y Competitividad (España) Ministerio de Educación, Cultura y Deporte (España) Hygienization Hydrochar Pyrochar Solid-state NMR spectroscopy Slow-release N fertilization 10 páginas.-- 4 figuras.-- 6 tablas.-- 43 referencias Hygienization by thermochemical carbonization may be one option to enable the use of sewage sludge (SS) as soil amendment and nitrogen (N) fertilizer. To evaluate this possibility, SS derived from different water purification processes of a rural waste water treatment plant were hydrothermal carbonized (HTC) at 200 and 260 °C for 0.5 and 3.0 h, and pyrolyzed at 600 °C for 1 h. During HTC, temperature rather than residence time affected the chemical alteration. Solid-state C and N nuclear magnetic resonance (NMR) spectroscopy showed considerably lower aromaticity in the hydrochars than in the pyrochars. Whereas the aromatic network of the hydrochars is dominated by polyfurans and N-heterocyclic aromatic units that of the pyrochars is mainly composed of arene structures. The highest total and inorganic N contents were obtained via HTC at 200 °C for 30 min, thus this material may be applied if both immediate and slow N release is needed. This work was supported by the Spanish Ministry of Economy and Competitiveness (projects PCGL2012-37041, CGL2015-64811-P and CGL2016-76498-R) and the Spanish Ministry of Education, Culture and Sport (Marina Paneque FPU fellowship, FPU 13/05831). Carlos Aragon and the Experimental Wastewater Treatment plant (CENTA) are acknowledged for providing the sewage sludge samples. Dr. Ulf Luder (Leibniz-Institut fur Agrartechnik and Bioengineering, Potsdam Germany) is thanked for his assistance during the production of the chars. Marta Velasco-Molina (IRNAS-CSIC, Sevilla) is gratefully acknowledged for her technical assistance.
