Much attention has been paid to municipal solid waste (MSW) incineration power generation and biomass energy. The co-firing power generation tests of MSW and biomass were performed in a MSW incineration power plant in North China. Experimental results showed that the running efficiency of generator unit had achieved the optimum state when the blended ratio was 14% (w%); the concentration of fly ash decreased greatly, and the concentration of SO2 and NOX increased slightly. These contents can be referenced in the running of MSW incineration power plant and the using of biomass energy later.

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.

As incineration is widely used in the disposal of municipal solid waste (MSW), the relation of harmful gas HCl, SOx, NOx, CO from incineration should not be neglected. In order to study the characteristics of HCl emission and removal during MSW incineration, several kinds of typical MSW components are selected for experiments in a Φ 150mm fluidized bed test rig. The effect of temperature on Cl → HCl conversion rate is discussed; the influence of HCl concentration on emission of NO, SO2 during incineration is analyzed. Finally the effect of Ca-based sorbents on dechlorination is also discussed. Results show that The Cl → HCl conversion rate varies obviously as temperature increases. With the increase of HCl concentration, the concentration of NO decreases, The inhibition of HCl to NOx is very obvious. At the temperature of 920 °C the capture of SO2 become more than at the temperature of 880°C. The type and amount of Ca-based sorbents can affect dechlorination rate.

Municipal solid waste has increased with the development of urbanization which sets a high request to the stability of landfill. The strength of anti-seepage slurry plays a crucial role in the stabilization of landfill. The ratio of each component was changed to test the slurry strength of different ages. Results show that the slurry strength increased with the raise of cement paste because the strength was mainly determined by the skeleton structure. In contrast, the excessive bentonite reduced the strength of slurry, for the excessive bentonite may package the skeleton structure of cement-fly ash instead of filling in. The dosage of Na2CO3 and PVA increasing to 3.0 g also reduced the strength of the slurry, because the water absorbability and expansibility of bentonite were inhibited and the effect of reinforcement on cement-fly ash structure was weaken.

AbstractMulti-objective optimization is one of the most effective tools for the decision support system. This study aims to optimize the gasification of municipal solid waste (MSW) for advanced power plant. MSW gasifier is simulated using Aspen Plus v11 to produce syngas, to be fed into power generation technologies. Four power generation technologies are selected, solid oxide fuel cell, gas turbine, gas engine, and steam turbine. Mixed-integer non-linear programming (MINLP) multi-objective optimization is developed to provide an optimal solution for minimum levelized cost of electricity (LCOE) and minimum CO2eq emissions. The optimization is conducted with a ε-constraint method using GAMS through time periods of 2020–2050. Decision variables include gasifier temperature, steam to carbon ratio, and power generation technologies. The optimization result demonstrates that the lower steam to carbon ratio gives lower LCOE and higher CO2eq emissions, and temperature variation gives no significant impact on LCOE and as it increases, CO2eq emission is reduced. It demonstrates that a gas turbine is the best option for generating electricity from 2020 to 2040 and beyond 2040 SOFC is the best option.
