Abstract: Sustainable procurement practices have emerged as critical mechanisms for achieving environmental, social, and economic objectives across global markets. This comparative policy review examines the barriers to sustainable procurement implementation in Sub-Saharan Africa and the United States, analyzing differences in regulatory frameworks, institutional capacity, and market dynamics. Through a systematic analysis of contemporary literature and policy documents, this study identifies key obstacles including corruption, limited technological infrastructure, inadequate policy frameworks, and varying stakeholder engagement approaches. The research reveals that while both regions face common challenges such as cost considerations and knowledge gaps, Sub-Saharan Africa confronts additional systemic barriers including governance deficits and resource constraints. The findings suggest that tailored policy interventions, enhanced international cooperation, and technology-driven solutions are essential for advancing sustainable procurement practices across both contexts.

Analysis of Seawater Quality Parameters and Treatment with Hydrodynamic Cavitation Method
Authors:-Divya Patil, Dr. Pankaj Gohil, Dr. Hemangi Desai

Abstract-The aim of the research was to compare the quality parameters of Seawater before and after hydrodynamic cavitation treatment. The Hydrodynamic Cavitation Method for water treatment gives the highest reduction in Turbidity (100%), the second highest reduction in TSS (83.86%), and the lowest reduction in Na+ (8.47%), according to the study and analysis of various quality parameters. When compared to CPCB Water Quality Criteria, treated water is suitable for outdoor bathing; it again satisfies the standards for classes SW-I, SW-II, SW-III, SW- IV and SW-V, i.e., treated sea water can be used for a variety of purposes, including bathing, contact water sports, commercial fishing, mariculture, ecologically sensitive zones, aesthetics, harbour, waters Navigation and Controlled water disposal. The SAR value of treated water, which is 1.72, indicates it is appropriate for all types of soil and crops. The treated water’s WQI, which is 65, showed that it is of Fair quality and may be used for industrial and irrigation uses. Water quality can be improved by recycling the treated water for an additional 24 hours using the hydrodynamic cavitation method. Recycling of one time treated sea water will result in higher-quality water that can be used for a variety of purposes. The Hydrodynamic Cavitation method by using venture orifice is proven to be the most effective over the other methods. Because it does not require any chemical reagent, hence does not produce any hazardous chemical waste, and maintains an eco-friendly and economically sustainable, environment benign technique for the treatment of Seawater.
