Oxygrow – The Living Urban Air Purifier
A revolutionary microalgae-powered photobioreactor that captures carbon dioxide and releases fresh oxygen, helping cities breathe cleaner while creating visually engaging public spaces.
Urban Spaces Are Running Out of Clean Air
Rapid urbanization has increased air pollution, carbon emissions, and reduced green spaces. Cities struggle to maintain clean air while balancing infrastructure growth.
Urban environments need innovative solutions that can improve air quality without requiring large land areas.
Problem Points:
- Air Pollution – Increasing pollution levels affect public health.
- Carbon Emissions – Rising CO₂ levels contribute to climate change.
- Limited Green Space – Dense cities lack space for trees and parks.
Meet Oxygrow
Oxygrow is an innovative urban photobioreactor that uses microalgae (diatoms) to perform photosynthesis similar to trees.
These microscopic aquatic organisms absorb carbon dioxide (CO₂) and release fresh oxygen (O₂), helping improve urban air quality.
Designed for modern cities, Oxygrow combines environmental impact with aesthetic design, transforming public spaces into cleaner, greener environments.
Measurable Environmental Impact
Urban sustainability often feels abstract—but OxyGrow makes it tangible, visible, and measurable.
Each OxyGrow unit is designed to actively improve air quality in its immediate surroundings by leveraging the natural efficiency of microalgae. Unlike traditional solutions that passively contribute to cleaner air, OxyGrow continuously works to capture carbon dioxide (CO₂) and release fresh oxygen (O₂) in real-time.
Through its advanced photobioreactor system, OxyGrow enables:
- Active CO₂ Reduction: Microalgae absorb carbon dioxide from the surrounding air as part of their natural metabolic process. This allows OxyGrow to directly contribute to lowering localized carbon concentrations in dense urban zones.
- Continuous Oxygen Generation: As part of photosynthesis, the system releases clean oxygen back into the environment, helping improve air quality in high-footfall public spaces.
- High Efficiency in Small Footprint: Compared to traditional green solutions like trees, OxyGrow delivers similar or enhanced air purification performance while requiring significantly less physical space—making it ideal for modern cities.
- Localized Air Quality Improvement: Whether placed in transit hubs, malls, or corporate campuses, OxyGrow contributes to healthier breathing environments for thousands of people daily.
By transforming invisible environmental impact into a visible, functional installation, OxyGrow helps cities and organizations take meaningful steps toward cleaner air and climate responsibility.

Microalgae Cultivation
Oxygrow houses microalgae inside a transparent photobioreactor chamber.
CO₂ Absorption
Microalgae absorb carbon dioxide from surrounding air.
Photosynthesis
Using sunlight, algae convert CO₂ into oxygen and biomass.
Oxygen Release
Clean oxygen is released into the environment.
The Science Behind OxyGrow
At the core of OxyGrow lies a powerful natural process—photosynthesis—enhanced through modern engineering and design.
OxyGrow uses a photobioreactor system that cultivates microalgae (specifically diatoms), microscopic aquatic organisms known for their exceptional efficiency in absorbing carbon dioxide and producing oxygen.
How the System Works
Air Intake and Circulation
Ambient air containing carbon dioxide and pollutants is drawn into the system through controlled airflow. This ensures continuous interaction between the surrounding environment and the microalgae culture.
Microalgae CO₂ Absorption
Inside the transparent bioreactor chamber, microalgae are exposed to light and begin absorbing CO₂ from the incoming air. These organisms use carbon dioxide as a primary input for growth.
Photosynthesis Activation
With the help of sunlight or integrated artificial lighting, the microalgae perform photosynthesis—converting carbon dioxide into oxygen and biomass. This natural process is significantly more efficient at carbon capture than many conventional methods.
Air Enrichment
The purified air, now enriched with oxygen, is released back into the surrounding environment, contributing to improved air quality in real-time.
Why Microalgae?
Microalgae are among the most efficient photosynthetic organisms on Earth. Their advantages include:
- Faster growth rates compared to terrestrial plants
- Higher CO₂ absorption efficiency
- Ability to operate in compact, controlled environments
- Continuous regeneration without seasonal dependency
By combining biology with technology, OxyGrow creates a scalable, reliable, and visually engaging solution for urban air purification.
