“…Based on the composition of landfill gas (Table D.4) and low heating value of CH 4 (Desideri et al, 2003), the net calorific value of landfill gas was estimated as 18-19MJ/m 3 , , which agrees with the range (19-23MJ/m 3 ) recommended by DTI (DTI, 2007a, DECC, 2009). …”

I also declare that the intellectual content of this thesis is the product of my own work, except to the extent that assistance from others with data collection and modification of process-oriented model DNDC is acknowledged. Miao GuoSep 2010 LCA of Light-weight Eco-compositesAbstract 3 AbstractThe environmental profiles of novel wheat based foam materials were investigated in this thesis using Life Cycle Assessment (LCA) methods. The LCAs were developed using primary data collected from industrial sources combined with new laboratory experiments supplemented with secondary data from publicly available sources.Laboratory research was conducted to obtain important missing data on WBFs for the LCA modelling, including physico-chemical parameters, biodegradability and energy recovery under anaerobic digestion conditions.Contribution analysis suggested that the emissions evolved from the wheat agroecosystem and PVOH production, together with the energy and infrastructure involved in WBF production were the major contributors to the environmental burdens of the WBF life cycle in most impact categories. The atmospheric emissions resulting from WBF degradation at the end-of-life also emerged as another important contributor to environmental impact. Amongst the diverse ‗end-of-life' scenarios examined, AD and home composting were suggested to be the optimum choices for WBF waste treatment. This research discusses two N 2 O modelling approaches and presents a method to expand the system boundary by integrating the process-oriented model DNDC for field emissions into the LCA. Sensitivity analysis suggests that the environmental profiles of agricultural products are influenced substantially by the system boundary definition. LCA of Light-weight Eco-compositesAbstract 4 Furthermore, it suggests that the ‗general rule' in LCA practice by applying an empirical model or a default emission factor (EF) could deliver unreliable LCA findings.This study also evaluated the sensitivity of the LCA results to methodology and data variations and quantified the uncertainties in the LCA outcomes arising from uncertainty in the inventory and data variability. This has led to an increase in confidence in the LCA findings. At the same time it indicates the areas where improvements in data or methods are needed in order for robust conclusions to be drawn and unbiased information to be delivered e.g. the methodological rigidity of characterization models, the IPCC Tier 1 EF uncertainty range.

“…However, the majority of landfills are only partially closed, thereby allowing the collection and treatment of the leachate, or kept open, leading to the gradual migration and dispersal of the leachate within the immediate ecosystem (Warmer Bulletin 2000;Nikiema et al 2004a;Zamorano et al 2006). Sanitary landfills can receive and process, over the period of their active life, more than a million metric tons of wastes (Desideri et al 2003;Zamorano et al 2006;Spokas et al 2006). For small cities and towns of less than 35,000 inhabitants, a municipal landfill of 20-30 m in depth is able to receive up to 200,000 m 3 of waste during its lifetime and is classified as a small landfill (Bö rjesson et al 2001;Park et al 2004).…”

“…The calorific value of biogas is typically around 20,000 kJ m -3 , i.e. about half that of the calorific value of natural gas and thus, the hot gases generated from biogas combustion can be best used as an energy source for the production of electricity and/or to generate hot water or steam (Goossens 1996;Desideri et al 2003;Tsai 2006;Zamorano et al 2006;Spokas et al 2006). This valorization process allows at least, the partial meeting of the energy demand for the wastes processing site and for other clients located in its neighborhood.…”

The production of biogas in landfills, its composition and the problems resulting from its generation are all reviewed. Biofiltration is a promising option for the control of emissions to atmosphere of the methane contained in biogas issued from the smaller and/or older landfills. A detailed review of the methane biofiltration literature is presented. The microorganisms, mainly the methanotrophs, involved in the methane biodegradation process, and their needs in terms of oxygen and carbon dioxide utilization, are described. Moreover, the influence of nutrients such as copper, nitrogen and phosphorus, and the process operating conditions such as temperature, pH and moisture content of the biofilter bed, are also presented. Finally, the performance of various filter beds, in terms of their elimination capacities, is presented for laboratory scale biofilters and landfill covers.

“…The use of biogas as a fuel source is environmentally sound because it contributes to a reduction of fossil fuel use and mitigates the greenhouse effect. In particular, the emissions of CH 4 , one of the two greenhouse gases emitted, are almost 21 times more dangerous than carbon dioxide for the greenhouse effect (Desideri et al, 2003).…”

“…Biogas is pumped from vertical wells (perforated piping in bulk of waste) and guided in well stations by horizontal pipes that connect each well with one well station. In well stations, biogas is rounded up and transmitted by primary horizontal network in the electric power station (Desideri et al, 2003;Ravena and Gregersenb, 2007). There, biogas is passed through appropriate equipment of dehumidification and elaboration (e.g.…”

AB STRACT:This study investigates the utilization of landfill biogas as a fuel for electrical power generation.Landfills can be regarded as conversion biogas plants to electricity, not only covering internal consumptions of the facility but contributing in the power grid as well. A landfill gas plant consists of a recovery and a production system. The recovery of landfill gas is an area of vital interest since it combines both alternative energy production and reduction of environmental impact through reduction of methane and carbon dioxide, two of the main greenhouse gases emissions. This study follows two main objectives. First, to determine whether active extraction of landfill gas in the examined municipal solid waste sites would produce adequate electric power for utilisation and grid connection and second, to estimate the reduction of sequential greenhouse gases emissions. However, in order to optimize the designing of a plant fed by biogas, it is necessary to quantify biogas production over several years. The investigation results of energy efficiency and environmental impact of biogas utilization in landfills are considering satisfactory enough both in electric energy production and in contribution to greenhouse gases mitigation.
