Advanced sewage sludge treatment can boost Chennai’s biogas production: study
A study by Anna University suggests that implementing advanced treatment technologies in Chennai's sewage plants could increase biogas production by 28%. While the sludge is viable for reuse, researchers emphasize that pathogen contamination must be addressed before it can be used for land restoration or forestry.
Why it matters
Optimizing sewage sludge management offers a sustainable solution for energy production and waste disposal in rapidly urbanizing regions.
While focus has largely remained on wastewater treatment, the reuse of sewage sludge is seldom optimised. In a recent study, Anna University has demonstrated that the adoption of advanced treatment technology in sewage treatment plants could increase biogas production by nearly 28% and be reused in various applications.
