Organobromine compounds comprise between 3 and 8% by weight of WEEE and mainly converted to HBr and Br in the incinerator. However, these compounds, during the cooling of the flue gases, can form the PBDD/Fs in the post-combustion area of the furnace. Due to the many benefits of Oxy-combustion process, our group has developed a fluidised bed incinerator for burning the WEEE and plan to maximise HBr/Br in the flue gas. Experimental results presented in the recent papers show that the combustion of the WEEE particles attains quickly to thermodynamic equilibrium. Thermodynamic modelling can, therefore, predict the concentration of brominated pollutants, particularly HBr, Br, HgBr, and Br˙ in the flue gas. In this paper, the effect of various parameters for increasing the HBr/Br ratio in the flue gas has been investigated. The model shows that the addition of very small amounts of hydrogen in the post-combustion area can convert Br and Br˙ into HBr.

NH-MIL-125 with abundant porosity and specific interactions with CO molecules, has been demonstrate great potential in the field of photocatalytic CO reduction. However, conventional NH-MIL-125 and their composites much lower CO photoreduction efficiency in aerobic environments because of the O competition. To circumvent the issue, this study modifies NH-MIL-125 through crystal facet engineering to enhance its selective CO adsorption and photocatalytic efficiency in the environment of impurity CO.

The disposal of municipal solid waste (MSW) is a significant source of greenhouse gas (GHG) emissions. As incineration becomes the primary method of MSW disposal in China, MSW incineration (MSWI) plants are expected to play a crucial role in mitigating GHG emissions in the waste sector. This study estimated the quarterly GHG emissions from two representative MSWI plants in Qingdao using a life-cycle assessment (LCA) approach.

Domestic waste treatment is an important source of anthropogenic greenhouse gas emissions, and it is of great significance to clarify the carbon emission intensity of each link before and after waste classification treatment to help with the "double carbon" goal. Based on the relevant data on domestic waste generation in Baoji City in 2021, combined with the integrated urban and rural domestic waste disposal model, the carbon emission intensity of urban and rural domestic waste treatment before and after classification was calculated using the IPCC inventory guide carbon emission factor method. The results showed that by reducing the proportion of simple landfills in rural areas, the carbon reduction could reach 59 451.

Among the various studies on CO2 utilization, the sustainable and cost-effective fixation of CO2 into cyclic carbonates remains one of the most intriguing subjects. To this end, a novel type of composite dicationic ionic liquid material, DIL@PDIL, was developed. This composite consists of a dicationic ionic liquid (DIL), DMAP[TMGH]Br, supported on a polymeric dicationic ionic liquid (PDIL), P-DVB/Im[TMGH]Br.

The direct CO2 reduction reaction (CO2RR) from simulated flue gas of various CO2 concentrations could minimize extra energy for pre-concentration processes to highly concentrated CO2 as a feed-stock. We investigate the challenges for CO2RR caused by low CO2 concentrations and provide strategies concerning the impact of the chosen electrocatalyst material and the selection of the electrolyte to attain high CO selectivity. We continuously feed CO2 mixed with N2 (the typical dilutant in flue gas) in various ratios to gas diffusion electrodes in a model flow-through electrolyzer.
