“…The analysis of GHG emission driving factors in the Yangtze River Delta region shows that energy conservation technologies have significant GHG mitigation potential . Furthermore, waste heat recovery can achieve significant results in terms of GHG mitigation . Besides, regional assessments based on different regional development goals in China are also important considering that not all focus on environmental or economic benefits .…”

Municipal solid waste incinerator fly ash (IFA) reutilization is energy-intensive with expenditure and secondary fly ash (Sec-FA) generation. Technology innovation and deployment are necessary for better IFA reutilization. Herein, potential benefits of technology innovation by fuel substitution, waste heat recovery and Sec-FA reuse of preferable plasma melting, fuel melting, and sintering technologies were evaluated by life cycle assessment (LCA) and life cycle costing (LCC). Results show that fuel melting and sintering could gain more environmental and economic benefits, respectively Technology innovation could bring environmental benefits and approximately 132 to 173 RMB/t IFA of economic profitability, among which waste heat recovery could gain 32–36% of economic optimization effect. A regional technology transition in China from plasma melting to fuel melting and technology innovation with waste heat and Sec-FA recovery shows GHG mitigation (0.48–0.79 Mt/yr) and economic benefits (322.21–537.02 million RMB/yr). Policy scenarios indicated that enterprise will lose approximately 360.70 RMB/t IFA if zero-subsidy is provided.

The purpose of the article was to conduct an in-depth literature review on the possibilities of managing combustion by-products (mainly fly ash) in the context of a closed-loop economy. First, information on the chemical composition of fly ash in Poland was collected and compared with the composition of fly ash in other European countries. The authors concentrated on describing methods for synthesizing geopolymers and zeolites using fly ash as a substrate. By-products of zeolite synthesis, which are strongly alkaline solutions, can be used as a substrate in the synthesis of geopolymers. A concept has been proposed to combine the synthesis of zeolites and geopolymers into a single process to close the material loop. The search for comprehensive technological solutions that take into account the ideas of a closed-loop economy is essential in an era of resource depletion, and this literature review encapsulates this topic area.
