“…Many pyro- and hydrometallurgical methods have been tried, mainly to extract nickel from these lateritic ores 13 Ammonia–ammonium carbonate leaching of the reduced ore has been carried out in the presence of oxygen, and about 70–75% of the nickel was extracted 4. Leaching with sulphuric acid has also been carried out at atmospheric as well as elevated pressure and temperature.…”

The management of huge volumes of overburden at chromite mines is a concern, and there is a need to make effective use of this material. Therefore, direct reduction of low grade chromite overburden from the Sukinda chromite mines was studied at high temperatures to recover Fe, Cr and Ni. The effect of process parameters, such as temperature, time, reductant and flux, on the recovery of these metals was studied. The bench scale results obtained were then used in laboratory rotary hearth furnace reduction experiments, where it was found that a cycle time of 25 min is required for maximum recovery of metal. It was observed that y90% of Fe and .90% of Ni were recovered and thus have the potential to reduce the volume of waste at chromite mines.

“…One of the growing applications of microalgae is towards the production of biofuel. 2,12–15 With growing concern for biofuel production, current research is now being focused on readily available and low-cost growth media for cultivating microalgae. In this regard, microalgal growth in nutrient loaded wastewater have gained more attention, and this indicates the possibility of removing nutrients from wastewater, while concomitantly achieving the desired biomass for production of biofuels.…”

Agricultural, domestic and industrial activities contribute in releasing several organic and inorganic substances into the water streams that result in environmental pollution. Biological treatment of industrial and domestic wastewater using Activated Sludge Nutrient Removal (ASNR), the conventional process, is well known; however, it is relatively expensive due to the requirement for high energy inputs. Microalgal applications have been gaining interest as they offer potential cost-effective measures for the treatment of wastewater in the peri-urban and rural areas. Such systems provide an interesting tertiary biological treatment method where valuable biomass is produced with simultaneous uptake of nutrients such as nitrogen and phosphorous with reduction in coliform bacteria, heavy metals, chemical and biochemical oxygen demand (COD & BOD) and the removal/degradation of xenobiotic compounds etc. This paper provides a systematic review on the current microalgal applications (phycoremediation) for wastewater treatment with advanced information on their role towards nutrient recovery and energy (biogas) production under the third generation biorefinery concept. The use of advanced algal pond systems for wastewater treatment including pollutant degradation, microalgal cultivation and employing such facilities for biogas production in view of technology applications is emphasized. This inter-linked network indicating microalgal role into the Nutrient-Energy-Wastewater nexus with future directions and concluding remarks are discussed.

“…The degradation of estuarine ecosystems often manifests as a simultaneous decline in multiple structures and functions, necessitating comprehensive assessments prior to implementing restoration techniques [24][25][26][27]. Regular assessment and monitoring are crucial to evaluate potential environmental damage resulting from anthropogenic activities that can cause largescale release of harmful compounds, non-toxic organic matter, and nutrients, leading to marine life mortality due to local nutrient accumulation and hypoxia [19,[28][29][30][31][32][33].…”

“…Risks associated with the transportation of various chemicals, fertilizers, petroleum products, coal, and iron ore, resulting in signi cant pollutant discharges during loading and unloading operations [25,32,[34][35][36][37][38]. The presence of major industries, and urban in the catchment, contributes to potential discharge of pollutants into the Mahanadi River, which eventually ows into the Bay of Bengal at Paradeep [39][40][41].…”

This study focuses on the environmental conditions of the Mahanadi Estuary near Paradeep Harbor and the adjacent sea. Data collected from May 2013 to April 2020 from 32 GPS fixed stations was analyzed to assess the water quality in different zones (estuarine, mixed zone, mixed zone south, and mixed zone north) of study area. Parameters such as pH, SST, TSS, nitrite, phosphate, silicate, TOC, chlorophyll, fecal coliform, and heavy metals were used to estimate the Water Quality Index (WQI) for each zone. The study found a deterioration (>30%)in the overall water quality of the Mahanadi Estuary from 2013 to 2020, potentially attributed to river inflows, port activities, and industrial outflows in to the coastal ecosystem. Seasonal variations in temperature, salinity, turbidity, nitrite, nitrate, and ammonia were observed. The water quality showed a deteriorating trend in estuarine, mixed zone, mixed zone south, and mixed zone north. Based on the water quality indices, the ecosystem shows moderate levels of stress. The degraded water quality highlights the need for a targeted mitigation plan to reduce external pressures and enhance the overall ecosystem quality.
