Sanghar Sugar Mills, Sanghar, Sindh, is a large agro-industrial operation generating wastewater volumes well beyond what smaller community or residential systems typically handle.
Critical GREEN designed and established a constructed wetland wastewater treatment solution, using biological treatment processes within an engineered wetland environment scaled to the mill's actual wastewater volumes and organic loads.
The completed system demonstrates that nature-based wastewater treatment can be engineered to match the scale of a major sugar mill, not just smaller decentralized installations.



We collaborate with engineering firms, technology suppliers, and consultants complementary to our environmental engineering focus.
