TreeAlgae replicates the photosynthetic efficiency of microalgae, found naturally in inland waters and oceans.
In a landmark innovation for environmental sustainability, PT Brigit Biofarmaka Tbk (OBAT) has unveiled TreeAlgae, a patented technology capable of reducing carbon emissions and purifying air by harnessing the natural photosynthetic processes of microalgae. The innovation, officially announced on January 23, 2025, positions Indonesia as a leader in sustainable smart technology, addressing pressing environmental challenges like urban air pollution and carbon emissions.
RELEVANT SUSTAINABLE GOALS
“This groundbreaking device leverages microalgae cells to absorb inorganic carbon dioxide and convert it into organic carbon stored as biomass, while continuously releasing oxygen into the atmosphere,” said Is Heriyanto, CEO of Brigit Biofarmaka, during a press conference in Jakarta.
How TreeAlgae Works: The Science Behind the Technology
TreeAlgae replicates the photosynthetic efficiency of microalgae, found naturally in inland waters and oceans. Each 200-liter unit of the system can absorb up to 336 kilograms of carbon dioxide annually, equivalent to the carbon absorption of 15 mature trees.
The system comprises four key components:
- Microalgae Breeding System: Encased in an aquarium-like structure, microalgae cells perform carbon absorption and oxygen production.
- IoT-Enabled Sensors: These monitor and optimize the system’s performance in real-time.
- Solar Power System: Ensures energy-efficient operation, promoting renewable energy use.
- Portable Design: The compact, movable design makes it ideal for urban environments where space is limited.
Heriyanto added that the device employs an advanced photobioreactor system, operated automatically to enhance the microalgae’s carbon absorption and oxygen production capabilities.
Urban Applications and Market Potential
With urban areas facing challenges in planting enough trees due to space constraints, TreeAlgae offers a practical alternative. “Imagine a compact aquarium filled with microalgae and equipped with cutting-edge technology. This is TreeAlgae—a solution designed for cities with limited green space,” Heriyanto explained.
The device is designed for easy maintenance, requiring reconditioning only every two weeks. Its compact dimensions, standing approximately 140 cm tall, make it adaptable for both indoor and outdoor environments.
The company plans to deploy 50 units of TreeAlgae in 2025, with each unit priced between IDR 150-180 million. OBAT has already secured 10 projects, including installations in Jakarta and parts of Kalimantan.
TreeAlgae’s development aligns with Indonesia’s growing participation in the global carbon market. “This innovation directly supports the international carbon trade recently introduced at the Indonesia Stock Exchange,” said Heriyanto.
Additionally, the device complements Indonesia’s role as a major global carbon sink, being one of the world’s top ten countries with vast forest cover. “This initiative is a step toward mitigating the effects of global warming and enhancing air quality for a better quality of life,” Heriyanto emphasized.
TreeAlgae represents a convergence of science, technology, and sustainability, offering a compact yet powerful tool for reducing carbon footprints. As urban centers grapple with rising emissions and limited green spaces, innovations like TreeAlgae could redefine how cities approach sustainability.
By combining the natural efficiency of microalgae with advanced IoT and solar technologies, OBAT’s TreeAlgae is poised to make a lasting impact—one unit, one breath at a time.
