“…When the WG is mixed with organic waste, it can not only produce hydrogen sulfide gas but also when the WG is landfilled into the inert landfill, the sulfate will leach into the groundwater. In short, the production of WG has harmed human health in addition to aggravating disposal problems [7,8]. erefore, the recycling of WG and the utilization of its recycled plaster are necessary to reduce the plaster of Paris consumption, reduce cost, save energy, and protect the environment.…”

In this work, Portland cement- (OPC-) blended recycled plaster materials (R-CP) were prepared to find out their hydration and mechanical properties. It was found that the hydration of R-CP was accelerated by the rapid rehydrated ettringite (AFt), and the strength of R-CP was decreased by the reduced hemihydrate content and low strength of rehydrated AFt and CaCO3. On the contrary, consistent with the previous studies, the strength of OPC-blended plaster of Paris materials (POCP) was improved by the formation of AFt, Ca(OH)2, and CaCO3 that filled pores in the pastes. Therefore, a different strength development could be seen in POCP and R-CP. In principle, these findings will lay a solid ground work for the utilization of recycled plaster.

“…López and Lobo (2014) reported SO4 concentrations of 100−800 mg-SO4/L and > 500 ppm H2S as the monitoring results at an actual landfill site. Even if 1000 ppm H2S were generated in the ground and H2S in the air were increased, the concentration would not reach 1000 ppm.…”

In order to suggest a limit value for gypsum (CaSO4) for the suppression of hydrogen sulfide (H2S) generation at an inert solid waste landfill site, the relationship between raw material (SO4 and organic matter) for H2S generation and generated H2S concentration, and the balance of raw material (SO4) and product (H2S) considering generation and outflow were investigated. SO4 concentration should be less than approximately 100 mg-SO4/L in order to suppress H2S generation to below 2000 ppm. Total organic carbon (TOC) concentration should be less than approximately 200 mg-C/L assuming a high SO4 concentration. The limit value for SO4 in the ground is 60 mg-SO4/kg with 0.011 w% as gypsum dihydrate, i.e., approximately 1/10 of the limit value in inert waste as defined by the EU Council Decision (560 mg-SO4/kg-waste). The limit value for SO4 in inert waste as defined by the EU Council Decision is high and TOC is strictly excluded. The cumulative amount of SO4 outflow through the liquid phase is much larger than that through the gas phase. SO4 concentration in pore water decreases with time, reaching half the initial concentration around day 100. SO4 reduction by rainfall can be expected in the long term.

“…The volatilization of the organic compounds from hazardous waste is the main pathway for the odorous emissions from the hazardous component of the waste [9], however the hazardous fraction is insignificant in municipal solid waste. The odor nuisance from construction and demolition (C&D) waste has been observed to be insignificant [10].…”

More than 60% of the waste dumps in India are within 500 m from the communities. The odor impact from these sites may be the sole criterion to prioritize these sites for closure/remediation. The existing rating systems do not consider odor impact in their assessment. A new system, proposed in the study, employs seven parameters derived from the literature review and selects their ratings based on data obtained from a survey of waste dumps in Indian cities having population more than one million and expert judgment. Application of the new system to the waste sites with continuously varying characteristics shows that the scores are spread over the full range of 0-1000 and have minimum clustering. The sensitivity analysis of the new system shows that the system exhibits medium to high sensitivity to five out of seven parameters employed in the system. The odor impact ratings for the fifteen waste dumps from the new system prioritize these dumps into three categories for remedial action and help suggesting a particular cover alternative for these dumps.
