“…However, due to the serious overcapacity of China's cement industry, with the gradual implementation of the national phase-out of cement production capacity and compression of cement production, as one of the cement production auxiliary materials, the preparation of cement retarder for phosphogypsum will also be affected. The latest research shows that phosphogypsum can also be used for soil improvement, and the improvement effect is remarkable (Enamorado et al 2014;Hentati et al 2015;Mao et al 2016). Similar to HMNS, a large number of PG also occupy a lot of open space, causing pollution to local groundwater (Li et al 2017;Papaslioti et al 2018).…”

High-magnesium nickel slag (HMNS) and phosphogypsum (PG) are hazardous industrial solid waste. The present work focuses on the feasibility of using the two materials as supplementary cementitious materials (SCM) added to cement. The slag and gypsum were ground into different specific surface area (2235 cm 2 /g, 3040 cm 2 /g and 3900 cm 2 /g), then mixed into ten different samples. The effect of SCM addition was detected by isothermal conduction calorimetry (ICC) testing, compressive strength, mercury intrusion porosimetry (MIP), X-ray diffraction (XRD), scanning electron microscope (SEM) and linear shrinkage. The results showed that the HMNS-PG composite cementitious material with suitable specific surface area has relatively high activity, and a small amount of gel and alumina-ferric oxide-trisulfate (AFt or ettringite) are detected in HMNS-PG composite cementitious material. According to the results, the high-magnesium nickel slag could be together with phosphogypsum as substitutes for cement, improved the utilization rate of industrial waste and reduced environmental pollution.

“…High levels of natural radionuclides and metals were also found in these wastes (Binnemans et al 2015). It is estimated that around five tons of this waste is generated per ton of phosphoric acid produced (Enamorado et al, 2014), which exceeds the mass of product, and 100 to 280 ×10 6 ton are produced worldwide (Cuadri et al 2014;Tayibi et al 2009). …”

Phosphogypsum (PG) is an industrial waste composed mainly by sulphate, turning it a suitable sulphate source for sulphate-reducing bacteria (SRB). In the present work the capability of two SRB communities, one enriched from Portuguese PG (culture PG) and other from sludge from a wastewater treatment plant (culture WWT-1), to use sulphate from PG, was compared. In addition, the impact of this sulphate-rich waste in the microbial community was assessed. The highest efficiency in terms of sulphate reduction was observed with culture WWT-1. The bacterial composition of this culture was not significantly affected when sodium sulphate from the nutrient medium was replaced by PG as sulphate source. Next generation sequencing (NGS) showed that this community was phylogenetically diverse, composed by bacteria affiliated to Clostridium, Arcobacter and Sulfurospirillum genera and by SRB belonging to Desulfovibrio, Desulfomicrobium and Desulfobulbus genera. In contrast, the bacterial structure of the community enriched from PG was modified when sodium sulphate was replaced by PG as sulphate source. This culture, which showed the poorest performance in the use of sulphate from PG, was mainly composed by SRB related to Desulfosporosinus genus. The present work provides new information regarding the phylogenetic characterization of anaerobic bacterial communities with the ability to use PG as sulphate donor, thus contributing to improve the knowledge of microorganisms suitable to be used in PG bioremediation. Additionally, this paper demonstrates that an alternative to lactate and low-cost carbon source (wine wastes) can be used efficiently for that purpose.

“…In addition, an investigation by Abril et al ( 34 ) showed that there is a positive correlation between Cd and 226 Ra levels in PG accumulated over the years of application. The increase in Cd levels was confirmed by Enamorado et al ( 38 ), who concluded that each kg of PG adds 2.1 mg of Cd to the soil.…”

Phosphogypsum (PG) is a waste by-product (residue) originating from the production of phosphoric acid and phosphate fertilisers. PG contains chemical and radioactive impurities, which is why it is mostly stockpiled in controlled areas. Worldwide, only about 15 % of PG is recycled or reused. Today, policies and business strategies prioritise sustainable development through circular economy, which certainly includes PG. This provides new opportunities for Croatia to manage its PG and make an effort to use it as an additive in different industries, such as agriculture and construction. Due to its chemical and radiological properties, PG can potentially cause problems for the environment and human health. Hence, before using PG, detailed knowledge of potential hazards is necessary to protect people and the environment. The aim of this review is to summarise available data on Croatian PG, compare them with other countries, and to identify knowledge gaps and the lack of data on potential hazardous substances in PG in order to assess the opportunities of using PG in Croatia.
