Project Abstract

Abstract
The processing of cassava roots into various food products generates a significant amount of waste in the form of processing water. This study focused on evaluating the levels of soluble solids and cyanide in cassava processing water waste and their impact on the biochemical oxygen demand (BOD) and biological toxicity of the aqueous environment. Soluble solids, including sugars and other dissolved compounds, are common in cassava processing water due to the leaching of constituents from the cassava roots during processing. Cyanide, a toxic compound present in cassava, can also leach into the processing water, posing potential risks to the environment and human health. The research conducted involved sampling cassava processing water waste from different processing units and analyzing the levels of soluble solids and cyanide. The BOD of the processing water samples was measured to assess the organic pollution potential of the waste. Additionally, bioassays using aquatic organisms were conducted to evaluate the biological toxicity of the processing water. The results indicated varying levels of soluble solids and cyanide in the cassava processing water waste, with concentrations exceeding permissible limits in some samples. The BOD values of the processing water indicated high organic pollution potential, highlighting the need for proper treatment before discharge into water bodies. The bioassays revealed significant biological toxicity in the processing water, affecting the survival and growth of the test organisms. Overall, the findings underscore the importance of addressing the management of cassava processing water waste to mitigate environmental pollution and protect aquatic ecosystems. Strategies such as implementing treatment technologies to reduce soluble solids and cyanide levels, as well as improving waste disposal practices, are crucial for minimizing the environmental impact of cassava processing activities. Furthermore, raising awareness among stakeholders about the potential hazards associated with cassava processing waste is essential for promoting sustainable practices and safeguarding water quality in affected areas. Further research is recommended to explore advanced treatment methods and sustainable management practices for cassava processing waste to ensure environmental sustainability and human well-being.
