Abstract

Sewage sludge valorization is currently performed mainly through biological processes (anaerobic digestion and composting). Even thought the composting process is well known from the point of view of its operation and process parameters, the evolution of organic matter along the process has been less studied. In this sense, this article uses two novel analytical techniques to follow the evolution of the organic matter during the composting of sewage sludge in an industrial facility. The applied techniques are dynamic respi-rometry and pyrolysis GC/MS.
