Abattoir wastewater, generated during the slaughter process, contains a complex mixture of pollutants that pose significant environmental and public health risks. These pollutants include organic matter, nutrients such as nitrogen and phosphorus, pathogenic microorganisms, heavy metals, and antibiotics, which can lead to surface and groundwater contamination, soil degradation, and adverse impacts on aquatic ecosystems. This review aims to provide an overview of the composition and characteristics of abattoir wastewater, highlighting its significant environmental challenges. The paper also examines Environmental Impact Assessment (EIA) methodologies for assessing and managing these risks, with a focus on wastewater treatment practices. Researchers discuss both traditional and advanced treatment methods, highlighting their effectiveness while also identifying the gaps and limitations they present. Case studies from various countries, including Nigeria, India, Brazil, the European Union, and the USA, are reviewed to illustrate both successes and challenges in wastewater management practices. The paper explores sustainable and eco-friendly solutions, including circular economy approaches, zero liquid discharge systems, and waste-to-energy models. This study outlines research gaps, future directions, and policy recommendations, emphasising the need for integrated treatment systems, real-time monitoring, and greater community engagement in wastewater management.
