The National Environment Management Authority (NEMA) has shut down a chemical company in Mlolongo for allegedly discharging untreated waste into the Nairobi River. The raid, led by NEMA Director General Mamo Mamo and Environment Cabinet Secretary Deborah Barasa, also resulted in arrests.

• Three individuals linked to the facility were arrested, with more expected to face prosecution.
• The company, specializing in glass, ceramics, and concrete, was found to be operating without a functional effluent treatment plant.
• The closure follows public outcry after social media images revealed white, foamy effluent flowing from the factory into the river, highlighting that an estimated 70% of Nairobi's wastewater is discharged untreated.
