“…It is widely accepted that the recycling of both CO 2 and the sorbent is indispensable in practical CCUS process ( Gao et al, 2020 ; Flores-Granobles and Saeys, 2020 ; Leclaire and Heldebrant, 2018 ; Gonzalez-Diaz et al., 2020 ). Therefore, in this study, the crystals of FuBIGH 2 (CO 3 ) (H 2 O) 4 were heated at 110°C in oven for one week for the investigation of the robustness of FuBIG in CO 2 capturing and releasing process.…”

Summary In this study, the concept of biomass-based direct air capture is proposed, and the aminoguanidine CO 2 chemical sorbent 2,5-furan-bis(iminoguanidine) (FuBIG) was designed, synthesized, and elucidated for the physicochemical properties in the process of CO 2 capture and release. Results showed that the aqueous solution of FuBIG could readily capture CO 2 from ambient air and provided an insoluble tetrahydrated carbonate salt FuBIGH 2 (CO 3 ) (H 2 O) 4 with a second order kinetics. Hydrogen binding modes of iminoguanidine cations with carbonate ions and water were identified by single-crystal X-ray diffraction analysis. Equilibrium constant (K) and the enthalpies (ΔH) for CO 2 absorption/release were obtained by thermodynamic and kinetic analysis (K 7 = 5.97 × 10 4 , ΔH 7 = −116.1 kJ/mol, ΔH 8 = 209.31 kJ/mol), and the CO 2 -release process was conformed to the geometrical phase-boundary model (1-(1-α) 1/3 = kt). It was found that the FuBIGH 2 (CO 3 ) (H 2 O) 4 can release CO 2 spontaneously in DMSO without heating. Zebrafish models revealed a favorable biocompatibility of FuBIG.

“…In the process and parameter optimization, the process parameters involved in the sewage treatment process need to be adjusted and controlled to optimize the technical strategy of greenhouse gas emission reduction [24]. In addition, corresponding emission reduction measures should be formulated from the aspects of reducing the energy consumption of wastewater treatment facilities and reducing the indirect emissions of greenhouse gases [25][26][27]. Various new greenhouse gas emission technologies have been combined to form a method with reference value for the overall planning and control of urban sewage system [28,29].…”

With the rising awareness of environmental protection, more sewage treatment plants have been built. However, this is also one of the main sources of greenhouse gas emissions. This study carried out a series of sewage treatment experiments to analyze the factors affecting the greenhouse gas emissions of the two commonly used treatment processes in the current urban sewage treatment: the A/O and SBR methods. The experimental results showed that the total amount of greenhouse gases emitted by the A/O method was 415.63 gCO2-eq/m3, and the total amount of greenhouse gases emitted by the SBR method was 879.51 gCO2-eq/m3. The N2O emission factor in the A/O method experimental group was 0.76% of the nitrogen content in the influent. In the aerobic section, when the content of dissolved oxygen was in the range of 1.30~2.10 mg/L, and the content of dissolved oxygen was 1.90 mg/L, the minimum N2O emission factor was reduced to 0.29% of the nitrogen content of the influent. In the SBR experimental group, the ammonia oxidation rate of sewage decreased rapidly as the temperature decreased, thus affecting the discharge rate of N2O. At 25 °C, the biological enzyme activity of nitrifying bacteria was higher, thus promoting denitrification and generating more greenhouse gases. The research results provide reference for strengthening the management of sewage treatment plants and reducing greenhouse gas emissions from sewage treatment plants.

“…It incorporated the survey-based outcomes, which are theoretically explained but focused only on the procurement protocols. Gonzalez-Diaz et al [ 29 ] analysed the various critics of the rice and wheat supply chain towards the avenues of decarbonisation. For the same, a life cycle assessment is done to estimate the levels of the carbon footprint being generated during the processing of rice and wheat.…”

The potential of decarbonising rice and wheat by incorporating carbon capture, utilisation and storage into fertiliser production

Abstract: This paper evaluates the reduction on greenhouse gas emissions in rice and wheat and their supply chains by incorporating CCUS into fertiliser production mainly from ammonia process, which is the section of fertiliser that produces the most CO2.
