Economic and environmental comparison between two scenarios of waste management: MBT vs thermal treatment

Refuse recovered biomass fuel from municipal solid waste. A life cycle assessment

“…Many studies have been carried out to assess the environmental performance of MBT technologies, especially versus WtE, and to demonstrate their environmental, resource and socio-economic relevance [6][7][8][9][10][19][20][21][22]. In spite of the recovery of additional resources and the range of possible energy recovery applications [20], MBT technologies increase system's complexity by adding inherent system losses, requiring additional energy consumption and representing a potential source of direct emissions.…”

A multilevel sustainability analysis of zinc recovery from wastes

“…Mass and energy balances have been performed based on the estimation provided in the literatures (Inglezakis et al, 2011;Panepinto et al, 2015;Surroop and Mohee, 2011), presented in Fig. 4.…”

“…• MSW input: 1000 t/d (equivalent to 41.7 t/h and 333.3 kt/y) • Operating hours per year: 8000 h • Fraction of mixed RDF and metal stream: 78.4% by weight of MSW (Panepinto et al, 2015) • Fraction of RDF: 70.2% by weight of MSW (Panepinto et al, 2015) • Fraction of residues to landfill: 1.9% by weight of MSW (Panepinto et al, 2015) • Energy generation from anaerobic digestion and CHP (Panepinto et al, 2015): -Total heat generation: 2.40 MWh per tonne of biogas • Total electricity generation: 1.83 MWh per tonne of biogas • Distribution of heat and electricity between internal use and selling (Inglezakis et al, 2011): -Heat: 28% (internal use) and 72% (sold), based on total heat generation • Electricity: 26% (internal use) and 74% (sold), based on total electricity generation • Energy generation from RDF incineration and CHP (Surroop and Mohee, 2011): -Total heat generation: 4.15 MWh per tonne of RDF. • Total electricity generation: 1.37 MWh per tonne of RDF.…”

Exploring untapped energy potential of urban solid 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). However, average data on electricity production vary from country to country because of varying composition of waste and different efficiency of the technologies being applied to the waste (Fruergaard et al 2009).…”
