“…The composition and diversity of the microbial community can vary depending on the feedstock and process conditions, influencing the efficiency of humification. Process duration: Longer durations allow for more complete decomposition of organic matter and the formation of more stable HS. However, excessively long durations can lead to the loss of valuable organic matter and a decrease in the overall efficiency of the process Nutrient availability: Adequate nutrient availability, particularly nitrogen and phosphorus, is crucial for the growth and activity of microorganisms involved in humification.…”

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.

“…The humification could be enhanced by adding biochar produced from digestate [11]. The addition of 25% biochar is optimal for encouraging the degradation of organic matter, minimizing NH3 emissions and increasing the formation of humic-acid-like matter, thereby increasing humification.…”

Food and Agricultural Organization estimates that roughly 1.3 billion kitchen trash are generated annually on a global scale. By using composting, we could convert our kitchen waste into a properly sanitized, humus-rich, relatively stable product that improves plant growth by conditioning soil Introduction. The main objective of this study is to conduct a review of fundamental of composting, humus, and enhanced humidification. Humus is created from degraded organic compound by the polymerization and condensation of organic components such polyphenols, reducing sugars, and amino acids. Humification can be increased through vermicomposting, the addition of biochar made from digestate, the addition of microbes to food waste compost, the addition of cow manure, multistage inoculation, solid state anaerobic digestion (SSAD), and composting hybrid processes.
