Research ArticleOpen accessIn the abstractPreliminary Tests Concerning Zero-Valent Iron Efficiency in Inorganic Pollutants RemediationSilvia Fiore, Maria Chiara ZanettiProblem statement: This study was aimed to a preliminary evaluation of the applicability of granular Zero-Valent Iron (ZVI) to the on site remediation of groundwater polluted by inorganic contaminants by means of a Permeable Reactive Barrier (PRB). A particular interest was devoted to groundwater impacted by Acid Mine Drainage (AMD) that was caused by the oxidation of metal sulphide minerals … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Gate to Gate Assessment of Environmental Performance for Production of Crude Palm Kernel Oil Using Life Cycle Assessment ApproachS. Vijaya, A. N. Ma, Y. M. ChooProblem statement: The oil palm industry is an export orientated industry which heavily relies on the world market. In 2007 alone the total export earnings reached RM 45.1 billion. It is essential that the oil palm industry is ready to meet the higher expectation of its overseas customers on the environmental performance of the industry. Life Cycle Assessment (LCA) is … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,225 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview on Landfill Leachate TreatmentsAbdulhussain A. Abbas, Guo Jingsong, Liu Zhi Ping et al.Problem Statement: Sanitary landfilling is the most common way to eliminate solid urban wastes. An important problem associated to landfills is the production of leachates. This study is a review of landfill leachate treatments. Approach: The advantages and disadvantages of the various existing leachate treatments discussed under the items: (i) Leachate channeling (combined treatment with domestic sewage, recycling) (ii) Biological … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 13,754 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Impact Assessment for Potential Continuous Processes for the Production of Carbon NanotubesAditi Singh, Helen H. Lou, Ralph W. Pike et al.As an emerging discipline, nanotechnology has the potential to improve environmental sustainability through its application in pollution prevention, treatment, remediation, etc. One challenging issue in the growth of nanotechnology is how to produce purified carbon nanotubes (CNT) in commercial quantities at affordable price and with low environmental impacts. A detailed assessment of such a manufacturing process from both economic and … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,600 accessesView PDFCite

Adarsh et al.Nine bacterial isolates were screened from different sites of East Calcutta Wetland, an ecosystem located at the eastern fringes of Calcutta. Other than being a biodiversity rich area, the important feature of this system is that it is a natural sewage treatment plant for the city of Calcutta. In addition to daily sewage including solid and soluble wastes, a considerable … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvolution 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 accessAll words, across the recordEffect of Municipal Solid Waste Compost on the Growth and Production of Vegetable CropsA.E. Ghaly, F.N. AlkoaikProblem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squash). Approach: Each crop … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,798 accessesView PDFCite
