“…Due to varying composition of waste, it is very difficult to accurately assess the energy value stored in the waste. However, according to a study by Murphy and McKeogh (2004) of all the available technologies, gasification was proved to be the best in terms of electric production, i.e., approximately around 1083 kWh/t MSW and for biogas the value was comparatively low, i.e., 151 kWh/t of MSW. Likewise for incineration, the electricity production was around 200 kWh/t (Cheng and Hu, 2010;Panepinto et al 2015).…”

There is continuous increase in quantum and variety of waste being generated by anthropogenic activities. Burgeoning amount of waste being generated has potential to harm the environment and human health. Aggravating the problem, ever-increasing energy demand is putting strain on the non-renewable sources of energy and there is huge gap between the demand and supply of energy. This has led the scientific communities to adopt innovative methods to reduce, reuse and recycle them. Therefore, there is an urgent need to minimize the quantity of waste and meet the current demand profile of energy is required; technologies to recover energy from waste can play a vital role in substantial energy recovery and reduction in waste for final disposal; in addition to meet the rising energy requirement. Generating power from waste has greatly reduced the environmental impact and dependency on fossil fuels for electricity generation. Economically also it is an optimal solution for recovery of heat and power from waste. This paper gives an overview of energy potential stored in waste, major available waste-to-energy technologies and also strategic action plan for implementation of these technologies.

“…), but they can be significantly reduced through the use of appropriate pollutant control systems. Murphy and Mckeogh (2004) reported that MSW incineration generating only electricity can produce approximately 220 g CO 2 /kWh e based on a net conversion efficiency of 15.3%. However, they do note that it is difficult to establish precise values due to the varying composition of MSW.…”

“…They are capable of reducing the volume of waste by up to 95% (Wong and Tam, 2014) and flue gas clean-up is generally less intensive. CO 2 emissions have also been reported to be lower than an incinerator at around 114g CO 2 /kWh e (Murphy and Mckeogh, 2004) . This is due to the assumption of a higher net conversion efficiency of 27.2%, and greenhouse gas emission per kilowatt hours will be of the same order if the entire thermal product is utilised.…”

A multi-criteria analysis of options for energy recovery from municipal solid waste in India and the UK

Energy recovery from municipal solid waste plays a key role in sustainable waste management and energy security. However, there are numerous technologies that vary in suitability for different economic and social climates. This study sets out to develop and apply a multi-criteria decision making methodology that can be used to evaluate the trade-offs between the benefits, opportunities, costs and risks of alternative energy from waste technologies in both developed and developing countries. The technologies considered are mass burn incineration, refuse derived fuel incineration, gasification, anaerobic digestion and landfill gas recovery. By incorporating qualitative and quantitative assessments, a preference ranking of the alternative technologies is produced. The effect of variations in decision criteria weightings are analysed in a sensitivity analysis. The methodology is applied principally to compare and assess energy recovery from waste options in the UK and India. These two countries have been selected as they could both benefit from further development of their waste-to-energy strategies, but have different technical and socio-economic challenges to consider. It is concluded that gasification is the preferred technology for the UK, whereas anaerobic digestion is the preferred technology for India. We believe that the presented methodology will be of particular value for waste-to-energy decision-makers in both developed and developing countries.

“…Because of the exponential growth of population and urbanization, coupled with the improvement of living standard and the development of social economy, the amount of MSW throughout the world has increased a lot, which poses a potential threat of environmental dilapidation (Karak et al, 2012). Therefore, MSW has been one of the key topics for environmental protection and resource utilization nowadays (Renou et al, 2008;Murphy and McKeogh, 2004). The last decade was characterized by great progress in development of MSW disposal, energy conversion methods, and management.…”
