Research ArticleOpen accessEvery word in the titleAnaerobic 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 accessEvery word in the titleProduction of Potassium and Calcium Hydroxide, Compost and Humic Acid from Sago (Metroxylon sagu) WasteC. P. Auldry, O. H. Ahmed, A.M. Nik Muhamad et al.Problem statement: Agriculture waste such as Sago Waste (SW) has a potential to cause pollution when the waste is discarded into rivers. In order to add value to SW, a study was conducted to produce potassium and calcium hydroxide, compost and Humic Acid (HA) from SW. Approach: The SW was air-dried and some grinded. The grinded SW was incinerated at … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,583 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproved Compost Production from Fruit and Vegetable Market Waste: A Case Study in Bagua, Amazonas (Peru)Juan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Wilfredo Ruiz Camacho, Juan Francisco Robles RuizInadequate management of organic solid waste in municipal markets represents a critical environmental challenge in tropical developing regions, where high humidity (>80%) and elevated temperatures (>25°C) accelerate decomposition, generating leachate and greenhouse gas emissions. In Peru, over 50% of municipal waste is organic, yet less than 20% is valorised through composting, highlighting a substantial technological gap. This study evaluated an … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 11 Aug 2026 · 1,262 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemediation of Heavy Metals by using Industrial Waste by Products in Acid Mine DrainageNuur Hani Mohammed, Mustapha Atta, Wan Zuhairi Wan YaacubAcid Mine Drainage (AMD) is one of the main important problems being combated today. Laboratory tank experiments were conducted to evaluate the use of industry waste to adsorb and control the mobilization of metals from contaminated acid mine water. The main physical conditions such as pH and treatment performance are displayed. The solution of acid mine were sampled from the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 18 Dec 2017 · 7,342 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction of Xylitol from Agricultural Waste by Enzymatic MethodsMarie K. Walsh, Hussein Fadhil Khliaf, Khalida A. ShakirEnzyme catalyzed production of xylose from autoclaved and non-autoclaved wheat straw was conducted followed by bioconversion of xylose to xylitol using a Crude preparation of Xylose Reductase (CXR) from Candida guillermondii. Ground wheat straw (autoclaved and non autoclaved) was treated at 40 and 50°C for up to 9 h at pH 4.5 with various concentrations of xylanase (12.4 to 37.2 … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 26 Mar 2018 · 9,655 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMicrowave-Assisted Co-Pyrolysis of Bamboo Biomass with Plastic Waste for Hydrogen-Rich Syngas ProductionN. Saifuddin, P. Priatharsini, S.B. HakimConcerns about diminishing fossil fuels and increasing greenhouse gas emissions are driving many countries to develop renewable energy sources. The knowledge of the dielectric property is essential to design and develop microwave technology for processing biomass materials. Bamboo biomass was subjected to microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 16 May 2016 · 9,121 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleEffect of Municipal Solid Waste Compost on the Growth and Production of Vegetable CropsA.E. Ghaly, F.N. AlkoaikProblem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squash). Approach: Each crop … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,798 accessesView PDFCite
