Pyrolysis study of sewage sludge by TG-MS and TG-GC-MS coupled analyses

Pyrolysis Analysis and Solid Residue Stabilization of Polymers, Waste Tyres, Spruce Sawdust and Sewage Sludge

“…These analyses were followed by several experimental tests carried out on a pyrolysis lab-scale reactor and a gas chromatograph (GC) as analyzer, in order to identify the evolved gas species. Although TG-MS/TG-GC-MS analyses allow to process a very small amount of waste (10-30 mg of sample), this instrumental analysis furnishes relevant information about the sample that are indispensable to study and scaling up a possible process treatment based on pyrolysis [9,10].…”

Thermal behavior and gaseous emission analysis during co-combustion of ethanol fermentation residue from food waste and coal using TG–FTIR

“…Most studies focused the burning characteristic and emissions of research target itself during the pyrolysis or oxidation process under different conditions, such as forestry waste [6][7][8][9], medical waste [10], sewage sludge [11], agricultural waste [12] and others. Chouchene et al [6,7] studied the kinetics and emissions from the pyrolysis and oxidation process of olive solid waste, he found that pyrolysis under oxidative conditions underwent three stages: drying, volatiles emission and char oxidation, whereas in the case of pyrolysis under inert conditions only the first two stages occur.…”

“…The research was essential for medical waste pyrolysis model, the TG-FTIR approach was important to provide valuable inputs for predictive modeling of medical waste pyrolysis. Ischia et al [11] and Giuntoli et al [12] investigated the pyrolysis of sewage sludge and agricultural residues in similar ways.…”

Thermal characterisation of the products of wastewater sludge pyrolysis

“…However, presence of metals and trace elements in wastewater sludge limits their use in agricultural application as a fertiliser. Disposal of wastewater sludge through landfilling should be avoided as it subtracts the soil from agricultural use [6,7]. On the other hand incineration reduces the volume of the sludge but it is costly and generates emissions to air, soil and water [8].…”
