Pyrolysis and combustion of two types of sewage sludge have been studied. The two sludges considered, considering their thermal decomposition, have different behaviors when comparing pyrolysis and combustion TG runs of each sludge. In one case, the combustion can be considered as an oxidative pyroly
Thermogravimetry and differential scanning calorimetry were used to examine, in nitrogen, four sewage sludges at modest heating rates. A mechanism consisting of two independent reactions was derived for an undigested sludge. The parameters are: n, = IO, Et = 130 kJ mol-', AI = 1 x IO'\* S-', nz= 15,
