Adsorption process both in post carbon dioxide capture and wastewater treatment has been receiving widespread attention over the past decades as a mitigating technology for climate change and water pollution, respectively. With this increasing interest in adsorption processes to address environmental concerns, development of an adsorbent with not just high adsorptive capacity but which is also low cost is of great interest among researchers. In this study, an agricultural waste which was already utilized as a boiler fuel in a paper industry was investigated for its potential as an adsorbent for both carbon dioxide capture and wastewater treatment. Specifically, the CO2 and methylene blue adsorption capacity of carbon residue from rice husk used as boiler fuel was determined and was compared with a biochar synthesized from rice husk. Furthermore, Scanning Electron Microscope (SEM) and Thermogravimetric analysis (TGA) were used for the characterization of the adsorbents. Results showed that the carbon residue can be a potential adsorbent for both applications with about 0.5 wt% CO2 adsorption and 100% removal of the methylene blue.

Faecal Bacteria

Attached algae settlement is frequently observed in effluents of wastewater treatment plants at locations with sufficient sunlight. For their growth they incorporate nutrients and the surface of the algal biofilm accumulates suspended solids from the clarified wastewater. During the photosynthesis process of algal biofilms oxygen is produced while dissolved carbon dioxide is consumed. This led to an increasing pH due to the change of the carbon dioxide equilibrium in water. The high pH causes precipitation of dissolved phosphates. Furthermore an extensive removal of faecal bacteria was observed in the presence of algae, which may be caused by the activity of algae. The experimental results indicate the high potential of these attached algae for polishing secondary effluent of wastewater treatment plants. Especially for small wastewater treatment plants a post connected stage for nutrient removal and bacteria reduction can be developed with the aid of an algal biofilm.

Results of the investigation of hide liming process wastewater treatment by carbon dioxide are presented in a paper. Comparison of the wastewater characteristics before and after the treatment by carbon dioxide was carried out. It was attempted to regenerate sodium sulphide using three different solutions: 10% solution of sodium carbonate and 5% or 10% solution of sodium hydroxide. The kinetic of sodium sulphide concentration, general alkalinity and pH was established. The solutions with the regenerated sodium sulphide were explored for unhairing of hide. The solution of 10% sodium hydroxide with regenerated sulphides was the mostly suitable for this aim. The properties of unhaired pelt were determined and assessed.

Metal Dichalcogenides

The material characteristics and properties of transition metal dichalcogenide (TMDCs) have gained research interest in various fields, such as electronics, catalytic, and energy storage. In particular, many researchers have been focusing on the applications of TMDCs in dealing with environmental pollution. TMDCs provide a unique opportunity to develop higher-value applications related to environmental matters. This work highlights the applications of TMDCs contributing to pollution reduction in (i) gas sensing technology, (ii) gas adsorption and removal, (iii) wastewater treatment, (iv) fuel cleaning, and (v) carbon dioxide valorization and conversion. Overall, the applications of TMDCs have successfully demonstrated the advantages of contributing to environmental conversation due to their special properties. The challenges and bottlenecks of implementing TMDCs in the actual industry are also highlighted. More efforts need to be devoted to overcoming the hurdles to maximize the potential of TMDCs implementation in the industry.
