The purpose of this paper is to discuss the alternative environmental management options for the utilisation of municipal solid waste (MSW) incineration fly ash (FA), which is generated at Iru Power Plant where MSW is incinerated in Estonia. To determine sustainable and economically feasible environmental management options for MSW incineration FA in Estonia, CO2 sequestration with a further carbonation process was examined. A partial Cost & Benefit Analysis has been conducted to compare the carbonation process to the current situation. Two carbonation options were developed. Option 1 is to use carbonated FA in any other processes based on the waste-to-product principle. Option 2 is to send carbonated FA to the non-hazardous landfill in Tallinn, Estonia. Important parameters, such as Net Present Value (NPV), Internal Rate of Return (IRR), Benefit–Cost Ratio (BCR) and Break Even Point (BEP), have been calculated for carbonation options and the current case. In addition, a sensitivity analysis has been conducted to examine its robustness. The results showed that the best option is carbonation Option 1 with NPV of 9,209,662 EUR, IRR of 43%, BCR of 2.63 and BEP between 2018 and 2019. Both Options 1 and 2 constitute more sustainable and environmentally friendly management options compared to the current situation. It can be concluded that this preliminary feasibility study showed that running a carbonation plant may be profitable and sustainable for Estonia. Currently, there is no treatment technology for MSW incineration FA in Estonia and FA is sent to a neighbouring country for further utilisation. This is the first study to demonstrate FA management options with economic and environmental benefits.

Currently, there are an estimated 1.3 billion tonnes of municipal solid waste (MSW) generated per year globally, and this quantity is predicted to increase to 2.2 billion tonnes annually by 2025. If not well treated, this rapid growth of waste products can lead to socio-economic and environmental problems. Waste is potentially a misplaced valuable resource that can be converted and utilized in different ways such as renewable energy resources for the realization of sustainable development. Presently, waste-to-energy technologies (WtETs) are considered to be an encouraging advanced technology that is applied to convert MSW into a renewable energy resource (methane, biogas, biofuels or biodiesel, ethanol, syngas, or alcohol). WtETs can be biochemical (fermentation, anaerobic digestion, landfill with gas capture, and microbial fuel cell), thermochemical (incineration, thermal gasification, and pyrolysis), or chemical (esterification). This review mainly aims to provide an overview of the applications of these technologies by focusing on anaerobic digestion as biological (nonthermal) treatment technologies, and incineration, pyrolysis, and gasification processes as thermal treatment processes. Landfill gas utilization technologies, biological hydrogen production processes, and microbial fuel cells also are assessed. In addition, the contemporary risks and challenges of WtETs are reviewed.

By expounding the concept of information visualization and municipal solid waste sorting, this paper illustrates the importance of information visualization design in municipal solid waste sorting. Then it conducts a systematic analysis on the current situation and existing problems of the visual language of municipal solid waste sorting at home and abroad from the perspective of information visualization design. Finally, it discusses the design countermeasures of information visualization for municipal solid waste sorting, thus providing a reference for the improvement of visual language of municipal solid waste sorting in China.

Complex Processes

A modern Municipal Solid Waste (MSW) landfill is a renewable energy resource to produce a significant amount of heat and methane used for generating electricity. However, it is difficult to use those sources effectively because active and post-closure MSW landfills are heterogeneous spatially and temporally and exposed to complex environments with varying pressure and moisture in the landfill. With regard to the prediction of the sources, the analysis of in situ MSW properties is an alternative way to reduce the uncertainty and to understand complex processes undergoing in the landfill effectively. A Hydraulic Profiling Tool (HPT) and Membrane Interface Probe (MIP) measures the continuous profile of MSW properties with depth, including hydraulic pressure, temperature, hydraulic conductivity, electrical conductivity (EC), and concentration of selected volatile organic compounds and methane. In this study, we conducted a series of MIP with HPT tests to investigate the MSW characteristics of a landfill in Nebraska. The results of the test showed an increase in hydraulic pressure and temperature with depth. The EC profile showed a variety of different waste constituents and MIP results showed the methane trapped beneath the top cover. The results in terms of hydraulic properties, temperature and EC obtained from different sites can be used to estimate the waste age and help designing energy recovery systems.
