Because of the global sustainability trend newenvironmentally friendly policies developed, world energy requirements go upmore slowly than in the former, however, it will still amplify by 30% betweentoday and 2040. (IEA, 2017).
Figure 1.8 energyconsumption by fuel source from 2000 to 2015, with growth rates indicated forthe more recent period of 2010 to 2015 (Source: Global Carbon Budget, 2016 and Jacksonet al., 2015) Consider of energy demand side its shift in therapidly growing and developing economic countries such as China and India,together with a slowing in overall energy growth as it is used ever more efficiently.And on the supply side, it’s moving into green energy sources dominant byrenewable energy sources, as a result of sustainability trends andtechnological improvements (BP Statistical Review of World Energy, 2017) 1.4.
1Waste to energy conceptWaste to energy concept is the process, whichinvolves waste for the generating of energy. In this process recovers energyfrom a variety of waste materials. The most common application by far isprocessing the Municipal Solid Waste (Eurostat, 2013). There are a variety of technologies have combinedwith the WtE concept.
Such asThermal technologies · Gasification· Pyrolysis· Thermal Depolymerization· PGP (Plasma Arc Gasification) Nonthermal technologies· Anaerobic Digestion· Mechanical biological treatment· MBT + Anaerobic digestion· Ethanol Production· MBT to Refuse Derived FuelThe implement of WtE projects necessitates combiningwith different organizations and technologies. Along with green energy conceptand integrated waste management system, the WtE concept is becoming the bestalternative solution to the decision makers. Because it’s addressed to allsectors of the economy and sustainability.
