## Abstract A semimicro‐method for determining nitrogen in sewage sludges is described avoiding the use of a micro‐balance or a micro‐burette. The whole estimation can be completed in just over one hour. Good agreement is shown between results obtained by this method and by the older Kjeldahl metho
The pyrolysis and combustion of 17 sewage sludges were studied by thermogravimetry. The dynamic experiments were carried out at 10 8C min À1 , and three different behaviours were observed at the decomposition curves. One of them shows combustion and pyrolysis curves that are parallel until high temp
