Özet
Sewage sludge is an important type of organic wastes among the various categories of solidwaste. Organic matter resources in soils are relatively low and frequently requirereplenishment. Therefore, the use of sewage sludge in agricultural soils is a desirablemethod of their utilisation. The addition of sewage sludge to soils may be an inexpensiveand effective alternative to the methods applied currently (mineral fertilisation, manureetc.). In spite of the undisputable advantages resulting from the application of sewagesludge in agriculture, it also involves some serious threats. Among those we should mentionthe presence of pathogens, heavy metals, and organic pollutants. In the current scenario ofincreasing global population, the generation of solid wastes like biosolids is bound toincrease remarkably. Improper and unscientific disposal of biosolids results in severalenvironmental issues such as surface and groundwater contamination, degradation of land,and food chain contamination. According to the principles of waste management hierarchy,agricultural recycling of biosolids will be a more environmentally preferred option over thetraditional disposal methods. Utilizing the potential of biosolids to recycle valuable plantnutrients and as an effective soil amendment will not only help in sustainable managementof this waste but also in minimizing the negatives associated with its traditional disposal.Every country must obey their regulations and legislations for managing their sewagesludge as a basic solution for use of sewage sludge in agricultural soil.
