The paper provides an overview of the potential use of humic substances (HS) derived from organic waste in transforming waste management practices. It discusses various types of organic waste, the production methods of HS, and their applications in agriculture, environmental remediation, and industry. The Perspective emphasizes the transformative potential of HS in reshaping organic waste management practices, highlighting improved soil fertility, mitigation of soil degradation, and immobilization of pollutants in soil and water systems. Additionally, it explores the economic viability of HS-based waste management and potential revenue streams from value-added products derived from HS. The paper also addresses environmental and regulatory considerations, emphasizing the importance of comprehensive regulatory frameworks, international policy and regulatory support, and continuous monitoring and evaluation of waste management practices. By integrating HS-based waste management into circular economy models, the paper suggests that it can contribute to resource conservation, nutrient recycling, and the development of a bio-based economy. Overall, the utilization of HS in organic waste management has the potential to revolutionize the field and contribute to sustainable resource recovery. The paper suggests that future research should continue to explore the quantifiable benefits of integrating HS into organic waste management, ultimately contributing to a more sustainable and efficient waste management system.
