Biochar as a Strategy to Mitigate Greenhouse Gases in Degraded Drylands of the Brazilian Semiarid Region: Carbon Stocks and CO2 Fluxes

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 1014-1026, December 2025.
This study evaluated the effects of pyrolytic biochars derived from co‐pyrolyzed sewage sludge and cashew residues on total organic carbon (TOC) recovery and CO2 emissions in degraded soils under greenhouse conditions. Biochar applications (5 to 40 Mg ha−1) enhanced soil carbon stocks and variably influenced CO2 fluxes over time.

Steady‐State Anaerobic Co‐Digestion of Aqueous Condensate From Municipal Sludge Pyrolysis

Water Environment Research, Volume 97, Issue 12, December 2025.
Anaerobic digestion of aqueous pyrolysis liquid (APL) was achieved despite its toxicity challenges. Optimal retention time, loading and acclimated inoculum improved APL conversion to methane. APL ozonation enhanced methane production, reaching 98% of theoretical yield.
