Identification and Environmental Consequences of Long-term Stored Chemicals in Ethiopia Pulp and Paper Industry

The study focuses on analysis of long term stored unknown chemicals and environmental impacts of stored chemicals at Ethiopia's Ethiopia Pulp and Paper Factory. In order to guide safe disposal or reuse, the goal is to identify and evaluate the chemical's qualities, especially its acidity, basicity, and composition. Both survey-based and laboratory methodologies are used in the investigation. While physical and chemical studies, such as pH measurements and cationic ion analysis, are carried out, information on chemical storage conditions is gathered using a standardized questionnaire. Soil samples gathered in the vicinity are examined to assess the environmental impact, and chemical samples are evaluated in water to ascertain their pH and solubility. Accuracy is ensured by multiple tests, the results of which are combined into averages and standard deviations. With pH values ranging from roughly 3.63 to 8.63, the results show that the compounds have a spectrum of weak acidic to weak basic characteristics. Aluminum sulfate is the main component found in the analysis, with traces of starch. Despite chemical contact, soil tests around the stored compounds are mainly neutral, indicating little immediate environmental damage. Sample variations indicate weak basicity or acidity, and the insoluble chemical further indicates intricate chemical interactions. The study confirmed that the stored chemical is mainly aluminum sulfate, a weak acid or base, posing limited environmental danger at current concentrations. The findings support safe disposal or potential reuse by industries, emphasizing the importance of proper chemical handling to mitigate ecological risks. Overall, the study provides a basis for informed management of chemical waste in industrial settings, promoting environmental safety and sustainable practices.
