Research ArticleOpen accessPhrase in the titleBehaviour of Main Microbiological Parameters And of Enteric Microorganisms During the Composting of Municipal Solid Wastes and Sewage Sludge in A Semi-Industrial Composting PlantOlfa Fourti, Naceur Jedidi, Abdenaceur HassenThis study was focused on the microbiological aspects of composting and on the behaviour of main prevalent microbial communities (non-pathogenic and selected pathogenic bacteria) during the composting process of municipal solid wastes and sewage sludge in a semi-industrial composting plant. Results showed that the dehydrogenase activity and Biomass C / Biomass N ratio showed a noticeable increase in the two … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,306 accessesView PDFCite
Research ArticleOpen accessPhrase 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
Research ArticleOpen accessPhrase in the titleHeavy Metals Content of the Grassland Soil around Katima Mulilo Municipal Solid Wastes Dumpsite, NamibiaJ. Abah, P. Mashebe, S.A. OnjefuThe effects of open wastes dumpsites on the immediate vicinity continue to generate safety concern. This study determined the levels of lead, chromium, cadmium, arsenic, nickel, cobalt, copper and manganese in soil samples collected at two depths: 0-15 and 15-30 cm within and around Katima Mulilo municipal solid wastes dumpsite and a control site. The samples were digested according to … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 18 Mar 2017 · 7,481 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEvolution of Microbial Biomasses C and N during the Composting of Municipal solid WastesOlfa Fourti, Naceur Jedidi, Abdennaceur HassenProblem statement: The aim of this study was mainly focused on the evolution of microbial biomasses C and N during the composting of municipal solid wastes. Approach: The carbon and the nitrogen of the microbial biomass (BC and BN) were studied using the fumigation-extraction method. Results: The dynamics of the BC/BN ratio, index of the chemical composition of the whole … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,702 accessesView PDFCite
Research ArticleOpen accessPhrase in the titlePlastic Solid Waste Assessment in the State of Kuwait and Proposed Methods of RecyclingS. Al-Salem, M. Al-SamhanA proper assessment of Solid Plastic Waste (SPW) in Kuwait will provide a greater understanding to the industry of plastic manufacturing and manufacturers as well as direct the strategic future plans proposed into execution. This research show the results obtained after a years survey and study of plastic solid waste in the state of Kuwait and the surrounding region in … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 7,416 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleMunicipal Solid Waste Generation and its Management, a Growing Threat to Fragile Ecosystem in Kashmir HimalayaRouf Ahmad Bhat, Moonisa Aslam Dervash, Mohammad Aneesul Mehmood, Khalid Rehman HakeemThe Kashmir valley is facing tremendous pressure associated with problems of growing waste generation. Thus, the aim of the present research was to generate baseline data for adequate waste management and associated problems. For the collection of samples, 20 houses were randomly selected in the main town from each district and segregated into compostable, recyclable, combustible and inert categories. All … …American Journal of Environmental Sciences, Vol. 13, Issue 6 · 13 Jan 2018 · 9,018 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffect 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
Research ArticleOpen accessPhrase in the titleFull Scale Tests of Short-Term Municipal Solid Waste Incineration Bottom Ash Weathering Before Landfill DisposalFranco Marchese, Giuseppe GenonProblem statement: Natural weathering is the most economic method of treatment in order to reduce the release of heavy metals present in the residue. Approach: The aim of the study was to optimize the minimum weathering times that were useful to reduce the lead release to within the Italian limits for landfill disposal. The mechanism of short-term weathering of MSWI … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,153 accessesView PDFCite
