Biohythane production techniques and recent advances for green environment – A comprehensive review

Hythane, characterized by its optimal H₂/CH₄ ratio (5–20%), emerges as an environmentally friendly solution for enhancing combustion engine efficiency while minimizing environmental impacts. Biohythane, a high-calorific-value blend of cleaner fuels, presents itself as a viable alternative for vehicles. The review emphasizes the global generation of organic biomasses and wastes by various industries, underscoring the potential for these organic wastes to be transformed into biofuels. This approach not only mitigates fossil fuel exploitation but also reduces greenhouse gas emissions, contributing to global climate change mitigation. The production of biohythane from organic wastes is positioned as a strategic initiative towards a circular economy. By maximizing the utilization of organic wastes and minimizing waste generation, this process aligns with sustainable practices and yields cleaner biofuels. In conclusion, this review contributes valuable insights into the production of biohythane as a sustainable and circular economy-oriented strategy. The novelty lies in the integration of organic wastes into the biohythane production process, offering a promising pathway to reduce environmental impact and combat climate change. The objectives encompass exploring production techniques, assessing influencing factors, and highlighting economic considerations, while the major outcome underscores the potential of biohythane as an environmentally friendly alternative to traditional fossil fuels.
