Emerald Leads SGD8 Million Investment in SG Enviro, Driving Advanced Industrial Wastewater Treatment in Southeast Asia

Emerald Technology Ventures, one of the global leaders in climate-tech venture capital, has announced a strategic investment in SG Enviro (SGE), a Singapore-based industrial wastewater engineering firm. The SGD8 million investment, led by Emerald, will support SGE’s expansion across Southeast Asia and the development and integration of proprietary technologies in its solution portfolio.

Founded in 2018 by environmental engineer Guah Eng Hock, SGE specialises in designing, integrating and operating industrial wastewater treatment technologies tailored to Southeast Asia’s unique requirements.

Emerald’s investment aligns with its strategy of fostering collaborations among its portfolio companies as well as corporates to accelerate the adoption of sustainable technologies. SGE will benefit from partnerships with other Emerald-backed global technology firms. It can differentiate itself by integrating leading edge technologies, while these tech companies benefit from accessing a growing yet distant market in SEA via a trusted partner.

SGE’s notable projects include the deployment of a large-scale AOP at an oil storage facility in Singapore, treating thousands of cubic meters of phenol-laden wastewater daily. The company has also secured contracts for retrofitting biogas wastewater systems at livestock farms and providing ongoing operations and maintenance services, establishing a recurring revenue model.

The investment will enable SGE to expand its footprint in Malaysia, Indonesia and other Southeast Asian markets, where industrial wastewater treatment infrastructure is in high demand.

“This investment marks a significant milestone for us,” said Guah Eng Hock, Founder and CEO. “It not only validates our belief that industrial water treatment in Asia requires region-specific, practical engineering – it also gives us Emerald’s support with curated global access to leading edge technologies to help us be more efficient in our operations and better serve their customers. Their network will also help us to scale up and create real impact across Southeast Asia.”
