Research ArticleOpen accessEvery word in the titleExploring the Reuse Potential of Chemical Sludge from Textile Wastewater Treatment Plants in India-A Hazardous WasteHema Patel, Suneel PandeyProblem statement: This study was conducted to explore the reuse potential of the chemical sludge (considered as hazardous waste as per Indian Government Hazardous Waste Management Rules) generated from combined effluent treatment in textile clusters. These textile clusters mainly cover the cotton dyeing and printing operations. Approach: Therefore, treatability studies of chemical sludge were conducted using solidification/stabilization treatment to examine … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,539 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReducing the Environmental Impact of Olive Mill WastewaterAwni Khatib, Fathi Aqra, Nader Yaghi et al.Problem Statement: A research was needed to monitor the environmental impact of olive mill wastewater (OMW): production and relative production of olive mill waste. This was achieved by collecting data from 92 local olive mills in order to study the olive production yield, water consumption in olive washing and in oil recovery, wastewater generation relative to olive processed and oil … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,043 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of the Detoxification on the Shrinkage Temperature and pH of Chromium Leather Waste, Another Promising Way for the Tannery PollutionA. Malek, M. HachemiThe leather tannery industry produces a significant amount of solid chromium waste. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. This research describes the possibility of decrease of the shrinkage temperature and to increase the pH value of leather waste by detoxification treatment with use of tartrate … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,114 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Typical Case Study: Solid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanThe current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,767 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSolid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanWaste management became focus of attention of many researchers and scientists in the last half century due to its vital importance. Waste management covered waste source reduction in general, by recycling, reusing, composting, incineration with or without energy recovery, fuel production and land filling. A common approach of waste management models were for specific problems with a limited scope (like … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,939 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvolution of Biochemical Parameters During Composting of Various Wastes CompostN. Saidi, M. Cherif, N. Jedidi et al.In Tunisia the most treatment waste is landfill (50% of wastes were land filled) and only 5% are composted. And since our soil become more and more poor in organic matter, green waste can be a significant source of organic matter; in parallel we cited the domestic waste and dead posodonia collected from beaches. All these wastes coming from various … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,933 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWaste Characterization in Steel Casting and Recycling Opportunities in EuropeSilvia Fiore, Maria Chiara Zanetti, Barbara RuffinoThe wastes coming from a steel foundry located in Italy, producing about 600,000 t/y of steel slabs, are considered in this work. The plant produces about 143,000 t/y of wastes, made of furnace and ladle slags (84%), pelletized dust (8%) and oxidised shaving (8%). The waste materials have been characterised by means of particle-size and chemical analyses, and some reuse/recycle … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,049 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleHeat Transport Modeling in an Aquifer Downgradient a Municipal Solid Waste Landfill in ItalyRajandrea Sethi, Antonio Di MolfettaHeat generation inside municipal solid waste (MSW) landfills is due to aerobic and anaerobic exothermic reactions occurring inside the waste. The result of heat generation and transport inside sanitary landfill leads to a temperature field that varies from mesophylic range (optimum at 30-40°C) to thermophylic range (optimum at 50-60°C). Due to high temperatures at the bottom of the landfill, liner … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,210 accessesView PDFCite
