Research ArticleOpen accessIn the abstractASSESSMENT OF ORGANIC WASTE MANAGEMENT METHODS THROUGH ENERGY BALANCEAntonio Comparetti, Pierluigi Febo, Carlo Greco et al.In Italy, the Organic Fraction of Municipal Solid Waste (OFMSW) is nowadays landfilled or processed through aerobic composting. The Italian towns currently support a high cost for OFMSW disposal and cause a high environmental impact, because of long distances travelled from towns to a few available landfills and fewer treatment places, as well as the used waste management methods. An … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 30 Sep 2014 · 7,212 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Formation by Ecological Factors: Critical ReviewSaeed Zeraat Kar, Aydin BerenjianRegolith is the term we give parent material that has been weathered. The regolith consists of weathered bedrock near the surface including the soil layer. In the Iranian soil layer we will find: decayed parent materials, decaying plant material, decaying animal matter (manure) along with vegetation. Results of the present study show us that methods stimulating natural fertility in Iran … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 2 Apr 2013 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Disposal and Pollution Management in Urban Areas: A Workable Remedy for the Environment in Developing CountriesJ. A. Awomeso, A. M. Taiwo, A. M. Gbadebo, A. O. ArimoroProblem statement: Both wastes and the crude disposal techniques have created subtle and yet serious environmental pollution havoc in many developing countries. This has lead to the degradation of abiotic and biotic components of these nations’ ecological systems. Poor industrial waste disposal systems as well as the indiscriminate and inappropriate domestic litter disposal habit have been identified and proved to … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 9,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractResidual Influence of Early Season Crop Fertilization and Cropping System on Growth and Yield of CassavaE. A. Makinde, O. T. AyoolaProblem Statement: In assessing fertilizer effects to sustain an intensive cropping system, the residual effects of fertilizer applied to preceding maize on the growth and yield of cassava and the effects of intercropping with soybean were studied in field experiments at Ibadan, Nigeria. Approach: Maize, established in April was fertilized using either organic manure or inorganic fertilizer or a mixture … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,967 accessesView PDFCite
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 PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Maturity Level in Laying Hen Manure by Chemical and Thermogravimetric AnalysisAlice Dall’Ara, Francesco Antolini, Laura Billi et al.This study aims at investigating maturity levels in manure from laying hens in order to encourage its agronomic re-utilization. In fact the use of unstable/insufficiently mature manure could potentially damage both soils and crops. Effective, easy to reproduce methods are needed in order to assess bio-stabilisation and maturity levels, particularly for biomass that has not undergone conventional composting. This study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Mixing on the Biological Degradation of Toluene under Aerobic ConditionsAbdel E. Ghaly, D.G. Rushton, K. MartinellThe effectiveness of in-vessel bioremediation in reducing the concentration of toluene in contaminated soil under continuous and intermittent mixing conditions using invessel composting system. The results showed that there was a startup period (60 h) during which the average temperature rose from 21 to 32 and 40°C (and then remained constant) for the bioreactors with continuous and intermittent mixing, respectively. … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,497 accessesView PDFCite
