“…Biogas generation rate depends on several factors (Bicheldey and Latushkina 2010;Rawat and Ramanathan 2011;Behera et al 2010;Machado et al 2009), such as waste composition and density, water availability and others site-specific conditions (e.g., temperature, pH, nutrients). In this work, gas generation is assessed using the simple anaerobic model proposed by Tchobanoglous et al (1993).…”

This paper presents an alternative water balance model for predicting leachate production in landfills, from the operative to the post-closure management. The developed model, based on analytical and empirical equations, provides a quantitative estimation of leachate volumes, using a water balance approach which accounts for the different rates of the incoming water, water losses and water consumption. Aging and compression are also included, allowing to assess the progressive variation of hydraulic and physical properties of deposited wastes. In this work, after a brief description of the model architecture, different applications to hypothetical scenarios and to a real landfill are presented. Namely, in order to highlight how aging and biodegradation can influence the expected leachate production, the results of the developed model are also compared with those provided by the Hydrologic Evaluation of Landfill Performance model which neglects both these processes. The obtained results showed that wastes compression may affect leachate prediction in a large extent during operative stage of a landfill, and neglecting these processes could lead to underestimation up to one order of magnitude. Also biodegradation of waste organic matter may result relevant for leachate volumes assessment, influencing water storage capacity of wastes and leading to a leachate production 2-3 times greater than those obtained neglecting these phenomena. Finally, the application of the developed model to the real landfill shows a quite good agreement with the field data, whereas the Hydrologic Evaluation of Landfill Performance model tends to underestimate the leachate volumes with errors up to 80 %.

“…In many developing nations, animal faeces have been composted and used to fertilize farm fields [1,2]. Many factors, including the type and concentration of substrate, temperature, moisture, pH, etc., may affect the performance of the anaerobic digestion process in the bioreactor [3,4]. The anaerobic digestion of organic waste is also an environmentally useful technology.…”

“…Based on the type of feedstocks, biogas contains 50-70% methane and 30-50% CO 2 and can be used to replace fossil fuels in power and heat production (Bajgain et al, 2005;Bond and Templeton, 2011;Katuwal and Bohara, 2009;Weiland, 2010). Biogas can be produced from wide ranges of biomass such as livestock farm-waste (manures, slurries and waste waters), crop residues, food (Behera et al, 2010;Chandra et al, 2012;Hill and Bolte, 2000;Liu et al, 2009;Weiland, 2010). In this regard, municipal solid waste (MSW), which is considered as the unwanted waste products, has a high potential for the generation of biogas through the anaerobic digestion (Hilkiah Igoni et al, 2008;Johari et al, 2012;Singh et al, 2011).…”

Municipal Solid Waste Management: Challenges and Opportunities in Nepal

Nepal is one of the least urbanized countries in the world where more than 80% of the total population live in rural areas. In recent years, the rate of urbanization became rampant which ultimately accelerated immense pressure on municipal services, especially on managing the ever increasing amount of wastes. Due to lack of technology, infrastructure and financial capacity management of increasing amount of solid waste has become a major challenge in municipalities of Nepal. The indiscriminate dumping of solid wastes already affected the urban environment by creating a serious occupational health and environmental hazard to the vicinity of the dumping sites. However, there is great possibility of recovering methane from the landfill sites since the typical Nepalese municipal solid waste contains more than 65% of organic wastes. Despite having enormous potential of generating electricity from hydropower, Nepal is facing acute shortage of energy. Therefore, comprehensive scientific research and development is necessary for making solid waste to environmentally friendly by converting waste to the energy.
