The article analyzes the impact of food imports from Russia and Ukraine on security Gulf Cooperation Council (GCC) countries. analysis focuses data collected by Food Agriculture Organization United Nations (FAO) 2000 to 2021 a literature review armed conflicts security. In context war between Ukraine, it is emphasized that negatively affects international stage, which may lead deepening crisis. Correlation linear regression were used determine relationship total GCC countries examine whether there these variables. correlation showed strong positive countries, while moderate relationship. However, was noted have taken steps in recent years become more independent single supplier agricultural products improve Ultimately, results suggest requires further attention action increase independence reduce risk shortages.

An approach to highly polluted wastewater management for zero liquid discharge: The case of landfill leachate

Process Safety and Environmental Protection, Journal Year: 2024, Volume and Issue: 184, P. 672 - 679

Published: Feb. 16, 2024

This work aims to bring the treatment of highly polluted wastewater concept zero liquid discharge, using landfill leachate as a representative example. Achieving this goal involves removing pollution due organic matter and/or heavy metals and recovering nutrients contained in effluent. Thus, sequential combination thermally activated persulfate Fenton reagent is proposed eliminate high concentration matter. avoids need pH adjustment meet process operation criteria minimizes amount and, consequently, conductivity treated Furthermore, solution particularly attractive systems with excess energy, such urban solid waste facilities where biogas generated. Nutrient recovery (N case leachate) carried out through precipitation form struvite. Finally, if necessary, further nanofiltration stage minimize effluent, making it suitable for on-site use. Under optimized operating conditions (Flow rate: 0.5 L h-1, residence time 60 minutes, 0.3 0.7 times stoichiometric (12 g/g COD0) H2O2 (2.12/g COD0), respectively, H2O2/Fe2+ ratio 50/1 85°C), 90% removal COD achieved, along 99% 95% nitrogen content effluent reclaimed water, confirming feasibility an approach more sustainable management.
