Research ArticleOpen accessIn the abstractTYPICAL MEXICAN AGROINDUSTRIAL RESIDUES AS SUPPORTS FOR SOLID-STATE FERMENTATIONDulce A. Flores-Maltos, Solange I. Mussatto, Juan C. Contreras Esquivel et al.Biological wastes contain several reusable substances of high value such as soluble sugars and fiber. Direct disposal of such wastes to soil or landfill causes serious environmental problems. Thus, the development of potential value-added processes for these wastes is highly attractive. These biological wastes can be used as support-substrates in Solid-State Fermentation (SSF) to produce industrially relevant metabolites with great … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHERMAL CONDUCTIVITY OF RUBBERIZED GYPSUM BOARDTaher Abu-Lebdeh, Ellie Fini, Ashraf FadielThe disposal of scrap tires is a challenging task and hence an innovative solution to meet these challenges is needed. Extensive work has been done on the utilization of waste tires in a variety of applications in asphalt pavements and concrete. However, previous investigations focus only on the mechanical properties of the rubberized materials, but few on the thermal performance. … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 14 Mar 2014 · 8,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractUSE OF CRUMB RUBBER TO IMPROVE THERMAL EFFICIENCY OF CEMENT-BASED MATERIALSAshraf Fadiel, Fouad Al Rifaie, Taher Abu-Lebdeh, Ellie FiniMotivated by the tremendous trend toward green environment and to reduce the effect of scrap tires on the environment and human health, this research is an attempt to find a practical and environmentally sound solution of the problem of scrap tires by developing a light weight with low thermal conductivity composite construction materials using waste tires. A few literatures may … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 14 Mar 2014 · 12,197 accessesView PDFCite
Research ArticleOpen accessIn the abstractBIOGAS PRODUCTION FROM TOFU LIQUID WASTE ON TREATED AGRICULTURAL WASTESBudy Rahmat, Tedi Hartoyo, Yaya SunaryaThe Tofu Liquid Waste (TLW) as a pollution might be processed into biogas which was environmentally friendly and had potential to replace burning wood or oil. However, the waste could not directly be employed as the biogas substrate due to the high nitrogen content which was not suitable to the methanogen microorganism on the biogas digester and did not produce … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 1 Feb 2014 · 7,952 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnaerobic Transformation of Biodegradable Waste; Simultaneous Production of Energy and FertilizerAmirhossein Malakahmad, Syazana Nasrudin, Noor Ezlin Ahmad Basri, Shahrom Md ZainAlmost 40% of the total waste produced in developing countries is made of biodegradable waste. Typically the waste including the biodegradable portion is transported to the so-called landfills without any segregation process, treatment and utilization in advance. Although mitigation practices such as source reduction, reuse and recycle are essential and required to be practiced in any integrated waste management plan, … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 10 Mar 2013 · 7,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Ethics in Governing Recycled Material Styrofoam for Building Human HabitatRavichandran Moorthy, Kartini Aboo Talib Khalid, Suhana SaadStyrofoam is extensively used in food packaging businesses throughout the world. Its light weight makes it a favorite food package for entrepreneurs in food businesses. However, unlike its content, the food, which decomposed easily after some time, Styrofoam remains un-decomposed due to its oil-based structure. This study discusses the prospects of re-utilization of Styrofoam as environmentally friendly recycled material. This … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 8,147 accessesView PDFCite
Research ArticleOpen accessIn the abstractTiO2 Nanoparticles-Coated Polypropylene Copolymer as Photocatalyst on Methylene Blue Photodegradation under Solar ExposureHasniah Aliah, Mahardika Prasetya Aji, Masturi et al.Problem statement: Pollutions of water bodies by dye wastes from textile industries and other sources have become critical consideration. A photocatalytic technique using semiconductor materials such as Titanium Dioxide (TiO2) activated by lights has been considered as one economical method to solve this problem. Approach: We attached titanium dioxide on the surface of polymer grains as photocatalyc agents using a … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 29 May 2012 · 7,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Nitrogen Containing Wastes Addition on Natural Aerobic Composting of Rice StrawThaniya Kaosol, Suchinun Kiepukdee, Prawit TowatanaProblem statement: Rice straw is an agricultural residue. Typically, the rice straw can be burn in the rice field after the harvesting process. The burning can cause air pollution. Another alternative rice straw management method is animal feed. The amount of rice straw is enormus in Thailand. Another sustainable way to manage rice straw is required. Rice straw is used … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 10 Mar 2012 · 8,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Decision Making Tool for Hazardous Waste Landfill Site SelectionP. Pandiyan, A. Murugesan, T. Vidhyadevi et al.Problem statement: Continuous global environmental crisis and degradation has been a challenge for the sustainability of living on earth. This threat was posed by industrialization, high products need, urbanization and population growth activities. As a result, the hazardous waste generation has tremendously increased. Approach: Landfill was one of the positive approaches to handle hazardous waste generated in great quantity. The … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,416 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Composition, Nutrients and Contaminants of Typical Waste Dumping SitesH. Meuser, K. S. Grewal, R. Anlauf et al.Problem statement: The composition of wastes is quite variable depending upon the generating source and mode of collection. Most of the material from the domestic activities will be organic in nature and contains essential plant nutrients, whereas the dumping material of commercial and industrial wastes usually contains appreciable amounts of heavy and potentially toxic metals and organic pollutants. Approach: Objective … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,753 accessesView PDFCite
