“…The feedstock fed to the process was excluded from the evaluation because, if not utilised, it would have to be disposed of. However, waste could be disposed with an energy recover, so in E3 we consider Maria et al, 2016) has been taken into account. Also observing trend of E3 value, the higher the LHV the lower the eective energy consumption.…”

Currently the production of methanol from Refuse Derived Fuel, a derived product of Municipal Solid Waste, can be deemed as an excellent example of circular economy, by representing a promising alternative both to conventional methods of waste disposal and methanol production from fossil resources. High-temperature conversion of waste in syngas is the main step of the Waste-to-Methanol process. Unfortunately, produced syngas does not directly comply with the requirements for methanol synthesis, in that syngas purication and conditioning steps are required. Moreover, waste, due to its heterogeneous nature, presents a variable composition, leading to the production of variable syngas owrate and composition. A thermodynamic equilibrium model of gasication unit has been developed in Aspen Plus environment and applied to analyse the eects of feedstock variability; RDF composition has been characterized considering as main parameters: ash, moisture and combustible fractions, carbon to hydrogen and carbon to oxygen ratios, and Lower Heating Value. Then, a simplied simulation of downstream process has been introduced to evaluate the inuence

“…When compared to a cement kiln, energy losses during heat transfer in a traditional WTE plant are much higher as the number of sites where heat transfer takes place are much higher. Therefore, a typical WTE plant can reach an average efficiency of 13% [18], which is much lower than a cement kiln. Some of the latest and state of the art WTE in Denmark are able to an efficiency of 27% [19].…”

Marine plastic pollution has become a major threat to the ecosystem. The increasing production and use of plastic, combined with limitations of waste management practices, mean the leakage of plastic waste into the environment is bound to increase. This study focuses on the determination of plastic recovery potential from dumpsites and landfills in Thailand, to potentially prevent marine plastic pollution. In this study, two dumpsites were analysed wherein an average of 42% of plastic was found to be present. This value, when extrapolated for Thailand, is equivalent to 187.9 million tonnes of plastic waste in dumpsites and landfills. While there are 2380 dumpsites in the country, this study suggests that 973 of these spread over 42 provinces are located near water bodies or coastline, which should be considered as a priority. The plastic waste recovered from these dumpsites can be treated by co-fuelling in cement industries. Cement kilns can valorise plastic waste as they can reach up to 75% energy recovery from waste, which is much higher compared to traditional waste-to-energy plants. With adequate incentives and sound regulations, cement industries could help in the reduction of marine plastic pollution with controlled emissions and a very large capacity to co-fuel cement production, there is a readily available solution to manage the large volumes of solid waste generated.

“…Due to the heterogeneous nature of waste, some differences with respect to conventional fossil fuel power plants have to be considered in the energy conversion process. The efficiency Energy Conversion -Current Technologies and Future Trends of a coal burning cycle is generally around 40%, while the efficiency of a garbage incineration cycle varies between 20 and 25%, if operating in a cogeneration mode, and up to 25-35% in the case of power production only [8,[26][27][28]. In general, fuel quality (i.e., waste) and other technical conditions (e.g., plant size, low temperature sources, etc.)…”

The contribution of this chapter is to deepen and widen existing knowledge on municipal solid waste (MSW) management by analyzing different energy recovery routes for MSW. The main aspects related to the composition of waste are addressed, as well as the technological routes for thermochemical and biochemical energy usage. Within the thermochemical route, incineration is currently the most utilized technology for energy recovery of waste, with generation of electricity and heat and also a decrease in the volume of the produced waste. Gasification and pyrolysis are alternatives for the production of chemical products from wastes. The biological route is an interesting alternative for the utilization of the organic fraction of MSW, as aerobic or anaerobic processes enable the production of biogas and of a compound that can be utilized as a fertilizer. Depending on the size of the population, composition of waste, and products to be obtained (energy or chemical), more than one technology can be combined for a better energy usage of waste.
