Pelwatte Dairy Industries Limited has commissioned its Effluent Treatment Plant (ETP) at its Buttala manufacturing facility, marking a significant milestone in the company’s journey toward environmental stewardship, ESG compliance, and responsible dairy processing.
The facility is the largest effluent treatment plant within a dairy processing operation in Sri Lanka, underscoring Pelwatte Dairy’s commitment to aligning its operations with global environmental standards while strengthening its position in international markets.
This investment reflects a deliberate, forward-looking strategy by the Board of Directors to embed Environmental, Social, and Governance (ESG) principles into core operations. As Pelwatte Dairy continues to scale its processing capacity and expand its export footprint, environmental compliance remains a central pillar of its sustainable growth agenda.
The ETP has been designed to meet increasingly stringent environmental requirements in Western, European, and Far Eastern markets, where compliance with wastewater discharge standards, environmental reporting, and sustainability practices are essential for market access.
The facility has a base treatment capacity of 250 m³ per day, with the engineered capability to handle peak volumes of up to 325 m³, representing approximately 30% additional capacity to accommodate future growth in processing volumes.
This future-ready design ensures that Pelwatte Dairy can maintain consistent environmental performance even under high production scenarios, reinforcing its commitment to long-term compliance, operational resilience, and responsible expansion.
The ETP integrates advanced treatment technologies, including Integrated Dissolved Air Flotation (IDAF), Anaerobic and Enhanced Sequential Batch Reactor (AnSBR/eSBR) systems, dedicated CIP wastewater management, real-time automated process monitoring, and screw press sludge dewatering.
