“…However that is the case in the Lan and Yuansheng [58] analysis. To exclude FGD (primarily used in the production of gypsum) we subtract the 76.6 Mtonnes of FGD that was produced in coal-fired power plants in 2011 [59]. 6 In 2003, 44.1 Mtonnes of fly ash were generated in EU (15) [60].…”

The paper illustrates the importance of capturing cross-sectoral relationships between industries in IAMs. • Retrofitting and clinker to cement ratio is not sufficiently represented in IAMs. • Retrofitting can offer considerable energy savings in the short-term. • Reducing the clinker content in cement can offer significant energy savings. • Limited future fly ash availability reduces the potential for clinker substitution.

Thermal Power Plant generates FGD gypsum as by-product during coal combustion. This study evaluates the characterization (spectroscopic and elemental), potentially toxic elements (PTEs) distribution, and environmental risk assessment of FGD gypsum for safe and sustainable use in agriculture. The XRD and SEM analysis confirmed the dominance of crystalline CaSO4·2H2O in FGD gypsum. The order of concentrations of PTEs in FGD gypsum was Fe > Al > Mn > Zn > Ni > Co. The residual fraction was the dominant pool, sharing 80–90% of the total PTEs. The heavy metals (HMs) were below the toxic range in the leachates. The Co, Ni, Al, Fe Mn, Zn had low (< 10%) risk assessment code and the ecotoxicity was in the range of 0.0–7.46%. The contamination factor was also low (0.0–0.16) at the normal recommended doses of FGD gypsum application for sodicity reclamation. The enrichment factor was in the order of Al < Mn < Co < Zn < Ni. Mn [enrichment factor (Ef) 1.2–2.0] and Co (Ef 1.7–2.8) showed negligible enrichment of metals, whereas Ni (Ef 4.3–5.2) and Zn (Ef 4.5–5.6) reported moderate accumulation in soil. The application of FGD gypsum @ 10 t ha−1 for sodicity reclamation will develop a geo-accumulation index below the critical values indicating its safe and sustainable use to achieve land degradation neutrality (LDN) and UN’s Sustainable Development Goals.
