“…So the sludge disposal may result in secondary environmental pollution if treated improperly. Among the different ways of sewage sludge disposal, land application is low cost and high effective and has been used widely [3][4][5]. However, application of sewage sludge may result in heavy metal accumulation in cultivated soils.…”

“…Different studies have been carried out on the processes commonly used for the stabilization and treatment of sludge, as well as the new technologies which have been developed in recent years. It should be noted that very good literature reviews on novelties in the field of treatment, use and disposal of sewage sludge are presented annually in the journal «Water Environment Research» [8][9][10][11][12][13].…”

The main objective of this work is to study the mechanical characteristics and the chemical degradation of mortars and concretes made obtained by substituting the cement by the machining sludge. Several materials were carried out by substituting the cement with different amount of machining sludge (5, 10, 15 and 20%). The obtained materials are compared to those without substitution (ie: 00wt% of machining sludge). Mechanical and physical properties of the two materials (mortars and concretes) as flexural and compressive strengths were studied. Physical properties as shrinkage, the bloating effect, loss in mass, slump concretes and porosity were evaluated. In addition, chemical degradation is studied for the conservation of these concretes and mortars from machining sludge in different aggressive environment. Moreover, the addition of 5wt% of the machining sludge in the mixture of the mortar and the concretes seems to be interesting.

“…The primary role of incineration is reduction ofthe waste volume prior to landfill disposal or precious metals recovery in the case of some industrial process sludges. Destruction of hazardous organics is another role of sludge incineration, especially relative to alternatives such as land application, landfill burial, and ocean disposal (Bowen et al, 1991).…”

Incineration is an important disposal method for the large volumes or sludge produced by industrial and municipal waste water treatment. This paper describes analytical methods developed for examining industrial sludge incineration processes and the dependence of potential products of incomplete combustion(PICs) on the sludge composition. A surrogate sludge was developed from peat, calcium and iron salts, and a waste water-treatment polymer suspension to simulate incineration characteristics of the real sludge while allowing for controlled variation of its composition. Experiments were conducted under both oxidative and pyrolysis conditions, in reactor systems ranging from microscale up to bench scale with on-line analytical instrumentation. The organic products emitted from the surrogate were quite similar to those of the sludge, with the exception or products from certain synthetic polymers. Significant quantities or aromatic hydrocarbons were emitted from the combustion of the cellulosic and lignin fractions of the material even without the presence or those specific compounds in the original waste. The presence of the metal salts and the additional water they retained significantly affected the peak hydrocarbon concentration by delaying the onset or emissions and lengthening their duration. The amount or polystyrene and polymethylmethacrylate in the real sludge made their decomposition products important potential PICs, which would need rurthercombustion.
