In order … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 21 Jul 2011 · 9,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Generation and Recycling: Comparison of Conventional and Industrialized Building SystemsRawshan Ara Begum, Siti Khadijah Satari, Joy Jacqueline PereiraProblem statement: In the Malaysian construction industry, there is a pressing issue of minimizing construction waste, which cause significant impacts on the environment. With the increasing demand for major infrastructure projects, commercial buildings and housing development programmers, a large amount of construction waste is being produced. Adoption of prefabrication and industrialized building systems is now a priority in the industry … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 9,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of Textile Dyes Ponceau-S and Sudan IV Using Recently Developed Photocatalyst, Immobilized Resin Dowex-11R. C. Meena, Ram Babu Pachwarya, Vijay Kumar Meena, Shakuntla AryaProblem statement: In present study, we selected a model dyes Ponceau S and Sudan IV, to test a recently developed photo catalyst methylene blue immobilized resin dowex-11. Approach: This is a light-activated process that has been successfully applied to remove organic and inorganic dyes of textile industries. Results: The reactor, made of glass slides (tubes) coated with a thin-film of … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Garbage Sorting MachineStephen Kwasi Adzimah, Simons AnthonyProblem statement: Domestic waste collection, sorting and disposal are major problems in many developing countries such as Ghana. It is an undeniable fact that the environment has been engulfed in filth. This filth comprises of the garbage and waste generated in homes, workplace and industrial setups. Most of this waste has found its way into the streets, gutters, in and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,514 accessesView PDFCite

TawariProblem statement: Elechi Creek of the Upper Bonny Estuary in the Niger Delta contributes to the Rivers State Fish resources. It is a sink receiving organic anthropogenic wastes from Diobu, Eagle Island and waterfront dwellers of Diobu areas. Fishing, car washing, bathing, swimming and other human activities are constantly going on within and around this creek. Based on these activities, … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Higher Sludge Recycling Rate on Anaerobic Treatment of Palm Oil Mill Effluent in a Semi-Commercial Closed Digester for Renewable EnergyAlawi Sulaiman, Zainuri Busu, Meisam Tabatabaei et al.Problem statement: A 500 m3 semi-commercial closed anaerobic digester was constructed for Palm Oil Mill Effluent (POME) treatment and methane gas capture for renewable energy. During the start-up operation period, the Volatile Fatty Acids (VFA) accumulation could not be controlled and caused instability on the system. Approach: A settling tank was installed and sludge was recycled as to provide a … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractFoundry Wastes Reuse and Recycling in Concrete ProductionSilvia Fiore, Maria Chiara ZanettiThe industrial process of a cast iron foundry plant located in the North of Italy was analyzed in order to determine the amount and kind of produced wastes.

Research ArticleOpen accessIn the abstractStabilization of Tyrosinase-Bovine Serum Albumin Crystals by GlutaraldehydeD. Norouzian, A. Akbarzadeh, M.H. Abnosi et al.Tyrosinase and bovine serum albumin were co-crystallized by saturated ammonium sulfate solution(65%) and 20% polyethylene glycol ( PEG) 6000 and n-propanol as co-solvents .The obtained crystals were cross linked by glutaraldehyde solution(1% v/v).Polyethylene glycol 6000 was found to be better co-solvent than n-propanol. The developed biocatalyst could be recycled 6 times without further loss of tyrosinase activity. No loss of … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffective Coagulation Technology for Treatment of Grease Filter WashwaterAbdel E. Ghaly, A. Snow, B.E. FaberThe treatment of grease filter washwater by chemical coagulation and sedimentation using different dosages of aluminum sulfate was investigated. Pollutant removal efficiency was measured in terms of total solids, pH and optical density. The process was found to be effective at the room temperature and the filter washwater pH (9.5). The optimum aluminum sulfate dosage was 2 g/L. The treatment … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 6,816 accessesView PDFCite
