Abstract

The increasing global concern over environmental sustainability has prompted a shift towards circular economy principles, aiming to minimize waste, promote resource efficiency, and foster a regenerative approach to production and consumption. This research explores the conversion of fly ash is obtained as a secondary product of coal combustion process, into valuable compost as a novel and eco-friendly solution within the circular economy framework. Fly ash, traditionally considered an industrial waste with potential environmental implications, can be repurposed into a valuable resource through innovative composting techniques. This study investigates the biological and chemical processes involved in the conversion of fly ash into nutrient-rich compost, highlighting the potential benefits in terms of waste reduction, resource recovery, and soil enrichment. The research employs a multidisciplinary approach, integrating principles of environmental science, microbiology, and engineering to optimize the composting process. Key factors such as microbial activity, nutrient cycling, and the influence of organic additives are examined to enhance the quality and effectiveness of the final compost product. Additionally, the study evaluates the potential of fly ash as compost is to improve soil fertility, sequester carbon, as well as mitigate environmental risks associated with traditional fly ash disposal. Through a life cycle assessment, the environmental impact of converting fly ash into compost is compared with conventional waste management practices, providing insights into the overall sustainability of the proposed circular economy solution. Economic feasibility and market potential are also explored, considering the commercial viability of large-scale fly ash composting operations. The findings of this research contribute to the growing body of knowledge on circular economy practices by presenting a sustainable and economically viable alternative for managing fly ash waste. The outcomes may inform policymakers, industries, and environmental practitioners in developing strategies to transition towards more circular and environmentally responsible waste management practices. Ultimately, this research aims to promote the integration of fly ash composting into circular economy models, fostering a greener and more sustainable future.
