Comparison of Specific Nutrients of Tunisian Textile Sludge and Produced Composts

Mohamed Anis El Hammadi, Melika Trabelsi and Belgacem Hanchi    

Abstract: The composting of textile sludge is an alternative to the traditional disposal of residues and also involves a commitment to reducing the production of waste products. A comparative study was made for major nutrient elements or macronutrients (include carbon, nitrogen, phosphorous, potassium, calcium) and the micronutrient elements mostly used (sodium, magnesium) present in the textile sludge taken from the a textile-wastewater treatment plant in the north of Tunisia. The two produced composts were made from the above sludge, mixed in two proportion (1:1 and 1:3 sludge and green plant waste (v/v)). The two produced composts showed higher C, N, Ca, Mg, K, P and lower Na contents than the above sludge. Sludge composting reduce the Na content of the sludge, provide a stabilized organic matter and improve the physicochemical properties of the textile sludge. However, other studies are necessary for a complete evaluation of the two produced composts before land application.
