“…Apart from that, it has been widely used in treating stabilized (Al-Hamadani et al 2011) and matured landfill leachate (Vedrenne et al 2012). In addition, the application of coagulation and flocculation can be used as pre-treatment process in order to remove non-biodegradable organic matter (Renou et al 2008).…”

“…Thus, leachate cannot be discharged to natural water bodies without appropriate treatment since it contains high concentrations of pollutants, such as organic substances (evaluated through the chemical oxygen demand (COD) and biochemical oxygen demand (BOD)), ammonia, heavy metals and inorganic salts. 7,10,11 As a landfill ages (> 10 years) the biodegradable fraction leached from organic pollutants decreases, since anaerobic decomposition occurs in the landfill. As a result, the organic compounds present in mature leachate are much more refractory than those found in leachate present in more recently established landfill sites.…”

One of the outstanding issues of concern by governments and society in general relates to the final destination of solid waste, which can bring severe impacts on social, political, economic and environmental dimensions. The sustainable development of enterprises and industries goes for the care of the planet, thus ensuring the quality of life for future generations and the planet. The disposal of municipal waste in landfills is the technique most commonly employed for the remediation of solid residues. The residues undergo decomposition beneath the soil and in the presence of water this generates leachate, which percolates down to the bottom of the landfill through drainage. This drained liquid is collected from the landfill installations and subjected to treatment, which involves physico-chemical and biological processes. Landfill leachate commonly contains heavy metals due to the incorrect disposal of products such as fluorescent bulbs and batteries. In this context, a method for the treatment of sludge originating from the physicochemical remediation of leachate using thermal plasma is proposed in this paper. The efficiency of the method was verified by monitoring the total organic carbon content, water content and density of the sludge. The quantity of metals present in the samples was determined before and after pyrolysis by thermal plasma using flame atomic absorption spectroscopy (FAAS), scanning electron microscopy (SEM) and X-ray fluorescence (XRF) spectrometry techniques. The results show that the leachate treatment method used was efficient, presenting the best results for the samples of iron and zinc.
