The issue of greenhouse gas emissions and global warming is currently one of the biggest environmental challenges. The legislation around carbon tax and emissions trading was originally mainly focused on fossil fuels and, therefore, the majority of the research on carbon capture has focused on
fossil fuel as well. However, there is a possibility that the legislation associated with the emissions of CO2will be extended to waste-to-energy plants. Waste-to-energy plants are, in terms of carbon capture, relatively specific and they differ from facilities combusting fossil fuels. An important aspect is that a
significant part of the incinerated municipal solid waste is often of biological origin. Therefore, some of the produced CO2 emissions are from renewable materials and, to achieve carbon neutrality, only a partof produced CO2 has to be captured. There are several technological solutions for post-combustion
carbon capture in various stages of the development process. The most developed technologies applicable for waste-to-energy are based on absorption (e.g. by monoethanolamine), adsorption (e.g. calcium looping), or membrane separation. The separation costs have been reported to be in favour of
amine absorption in the case of a large scale and/or when a vast majority of produced CO2 needs to be captured. On the other hand, it has been reported that membrane separation can be economically advantageous when only a part of produced CO2 is to be captured at a waste-to-energy plant. An experimental investigation of separation properties of a commercial membrane module was conducted and, based on this investigation, the energy demand and economic impacts of the separation process were assessed.
