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 abstractHeavy Metal Contamination of Soils and Water Resources Kettara Abandoned MineManuel Valiente, Gustavo Perez, Marta Avila et al.Problem statement: Metal mining; together with mineral smelting and processing, have contaminated the environment surrounding mine areas throughout the world exceeding natural background concentration. Approach: These processes introduce metal contaminants into the environment through gaseous and particulate emissions, waste liquids and solid wastes. The principal objective of this study was to investigate soil and water contamination in the vicinity of … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 8 May 2012 · 8,831 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Applied Study on the Debris Recycling in TunnellingPierpaolo Oreste, Marta CastellanoProblem statement: A simple calculation has shown what the impact of muck created during the construction of a hypothetical 50 km long and 100 m2 cross section tunnel could be on the environment: around 8 million cubic meters would have to be discharged as waste material. One solution to such a problem could be to recycle (almost a part) the … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 27 Mar 2012 · 7,518 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 abstractExtraction, Purification and Characterization of Fish Chymotrypsin: A ReviewLiang Zhou, Suzanne M. Budge, Abdel E. Ghaly et al.Problem statement: Solid fish waste is generated from the unwanted parts of fish including heads, tails, fins, frames, offal (guts, kidney and liver) and skin. It accounts for up to 80% of material from production of surimi, 66% from production of fillet and 27% from production of headed and gutted fish. Currently, fish wastes are disposed off in land-based waste … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 10,585 accessesView PDFCite

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 abstractA Review of Static Tests and Recent StudiesSrilert ChotpantaratProblem statement: Acid mine drainage from waste rocks, tailings and other mine components, is one of the most important environmental concerns at mining sites. To attempt to determine the balance between the acid and neutralization potentials of the material and evaluate the possible acid-forming potential of mine waste, many static prediction tests have been developed to evaluate the acid-forming potentials … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 19 Apr 2011 · 7,658 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquilibrium Kinetics and Isotherm Studies of Cu (II) Adsorption from Waste Water onto Alkali Activated Oil Palm AshZaira Zaman Chowdhury, Sharifuddin Mohd. Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,933 accessesView PDFCite
