The Digest’s 2025 Multi-Slide Guide to Biogas Engineering’s Multi-faceted Roles and Global Potential

Biogas engineering offers five key roles: emission mitigation, renewable energy, fertilizers, environmental protection, and soil improvement. A newsworthy aspect is Biogas with Carbon Capture and Sequestration (BGCCS) for negative emissions. China demonstrates immense biogas potential from agricultural waste, projecting significant contributions to natural gas needs and methane reduction. The “Great Cycle” concept integrates these benefits. Challenges include technology, policy, and finance, underscoring the need for international collaboration and standardized methodologies for scaling.
