Bioremediation of Tunisian Textile Sludge by its Co-composting with Green Plant Waste

Mohamed Anis El Hammadi, Melika Trabelsi and Belgacem Hanchi    

Abstract: With the increasingly growing production of textile sludge in Tunisia, evaluation of its use in composting process is essential. The sludge was produced in a textile manufacture in north of Tunisia and the composting system designed involved open piles turned periodically over a period of 3 months proved to be inexpensive and reliable. This experiment examined co-composting of textile sludge with green waste at 1:1 v/v (pile 1) and 1:3 v/v (pile 2) ratios in periodically turned outdoor piles, which were sampled for analysis after the beginning of the composting process. Changes in the composition of the two mixtures were determined by monitoring chemical and microbiological parameters. The produced compost C1 shows a higher C, N, pH and dry matter contents. Organic matter concentration at the end of composting was lower in C1 than C2. The amount of heavy metals and pathogens present in the final product is lower than the amount mentioned for the waste compost use in French norms.
