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 · 7,229 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 · 13,764 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 · 7,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Metal Accumulator and Protease Secretor Microbes from East Calcutta WetlandSanhita Chowdhury, Madhusmita Mishra, V.K. 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 · 8,991 accessesView PDFCite

Approach: Two different protocols have been used taking particularly into account the problems connected to sludge heterogeneous composition and to … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,370 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCo-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane ProductionA. Sulaiman, M. R. Zakaria, M. A. Hassan et al.Problem statement: Refined Glycerin Wash Water (RGWW) from the oleochemical industry contains high Chemical Oxygen Demand (COD) and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl) that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME) for … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,937 accessesView PDFCite
