“…Solidification/stabilisation (S/S) was utilised extensively in the 1950s to treat atomic wastes and after that was generally sought for the treatment of hazardous wastes in the mid-1970s (Barth 1990). The technology is being connected to:…”

In the whole world today there has been a growing awareness of the damage caused to the environment by the haphazard use of chemicals, some of which are very poisonous and carcinogenic. The textile industry has been strongly criticised as being one of the world's worst lawbreakers in terms of pollution because it demands a large amount of water and chemicals. Although air, water, and noise pollution are created at every step of fabric treatment, the most problem-filled is fabric wet processing, in terms of the huge amount of water and goodly number of chemicals used in wet processing and on completion of the process, leftover dyes and chemicals together with water are discharged as effluents. As the amount of sludge created by wastewater treatment increases, effective reuse and safe disposal of sludge becomes most important. This chapter provides comprehensive information about the various methods and techniques in recycling textile effluents and sludge treatment process of textile effluents.

This paper presents a study on the mechanical properties of a contaminated clay soil and its treatment by cement. One group of unconfined compression (UC) tests was performed on samples of natural soil, and soil contaminated by Mono Ethylene Glycol (MEG) with 40% concentration at different degrees of contamination (3, 6 and 9%). Another group of UC tests was conducted on the samples that were prepared as mixtures of clean or MEG contaminated soil with different cement contents (3, 6 and 9%) at different curing times.The results show that the strength and stiffness of the soil contaminated with MEG is reduced increasingly by the degree of contamination. In addition, by adding cement to the contaminated soil, the strength of the soil is increased as a function of degree of contamination, percent of cement and curing time.

“…The pulverized fuel ash (PFA), which is a siliceous and aluminous material, is used as an alternative binder to PC in the S/S process in conjunction with lime, and the corresponding reactivity depend on the relative fineness of the content and the glass phase ratio (Dhir 1986;Harris et al 1995;Neville and Brooks 2010). The metals in the contaminated soil, if treated with PFA-lime binder, might get chemically immobilized as hydrate complexes (Barth 1990;LaGrega et al 2001). However, the hardening process of PFA is slower (Taylor 1992) and exhibit reduced sustainability during both leaching and durability tests than that of the PC (Harris et al 1995).…”
