The increasing demand for sustainable environmental practices has underscored the necessity for innovative waste management solutions. This article explores the transformative potential of biogas and bio slurry in sustainable environmental management. Biogas, produced through anaerobic digestion of organic waste, offers a renewable energy source that mitigates greenhouse gas emissions and reduces reliance on fossil fuels. Concurrently, bio slurry, the byproduct of biogas production, serves as a valuable organic fertilizer that enhances soil health and boosts agricultural productivity. This dual-faceted approach not only addresses waste disposal challenges but also promotes circular economy principles. The article examines the benefits of bio slurry as a soil amendment. By integrating biogas and bio slurry into waste management strategies, this study advocates for a holistic model that supports environmental sustainability, energy security, and agricultural resilience.
