Research ArticleOpen accessIn the abstractDetermination of Rheological Properties of Bio Mastic AsphaltR. Muniandy, H. Jafariahangari, R. Yunus, S. HassimDue to the high oil prices the price of asphalt binder has increased tremendously. This scenario has warranted demand for higher viscosity cheaper asphalt for pavement construction. A study was conducted to take advantage of the Empty Fruit Bunch (EFB) of Date and Oil Palm trees (which are considered as waste) to produce cellulose fiber to be used as additives … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 8,067 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA 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 PDF Cite

Research ArticleOpen accessIn the abstractSolid 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 PDF Cite

Research ArticleOpen accessIn the abstractTreatment of Stormwater Runoff and Landfill Leachates Using a Surface Flow Constructed WetlandA. Snow, A. E. Ghaly, R. CoteA surface flow wetland was constructed in the Burnside Industrial Park, Dartmouth, Nova Scotia, to treat stormwater runoff from the surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The aim was to protect a freshwater ecosystem that consists of a 4.6 km long brook and two lakes. The ability of the constructed wetland to retain … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,747 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUptake and Translocation of Manganese by Native Tree Species in a Constructed Wetland Treating Landfill LeachatesA. Snow, A.E. GhalyA surface flow constructed wetland was used to treat stormwater runoff from surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The uptake of manganese by red maple, white birch and red spruce trees growing under flooded soil conditions in the constructed wetland was compared to that of the same trees growing under well drained soil … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 7,505 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHeat 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 PDF Cite

Research ArticleOpen accessIn the abstractA Comparative Assessment of the Characteristics of Saturated Wetland Soil and a Well Drained Forest SoilA. Snow, A. E. GhalyA surface flow wetland was constructed in the Burnside Industrial Park, Dartmouth, Nova Scotia, to treat stormwater runoff from the surrounding watersheds which are comprised primarily of commercial properties and two former landfills. The aim was to protect a freshwater ecosystem that consists of a 4.6 km long brook and two lakes. A comparative analysis of the pH, total and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,630 accessesView PDF Cite
