Summary

An integrated pyrolysis process applied to municipal sewage sludge simultaneously produces hydrogen fuel and destroys microplastics that concentrate in sludge during wastewater treatment. This dual-benefit approach addresses sewage sludge as a critical microplastic reservoir, offering a thermal elimination pathway before sludge is land-applied and microplastics enter soil ecosystems.

Study Type Environmental

Municipal sewage sludge, a byproduct of wastewater treatment processes, is increasingly recognised as a significant reservoir of microplastics (MPs), posing risks to soil and aquatic environments.
