A systematic assessment of environmental impacts and techno-economic benefits of solid digestate conversion to biochar: a case study of pig farm digestate in Taiwan
Digestate, the solid by‑product of anaerobic digestion, can cause nutrient leaching, greenhouse‑gas release and heavy‑metal accumulation. Slow pyrolysis offers a promising route for upgrading digestate into biochar, yet its high energy demand and uncertain economics must be carefully weighed. This study evaluates the f...
