A Nature-Based Innovation Transforming Wastewater into Opportunity
We are pleased to announce that our innovative Floating Bio-Island for Wastewater Treatment has been recognized by the Waste Free '23 Technical Repository, a global platform spotlighting grassroots innovations that offer scalable, sustainable solutions to today’s most urgent environmental challenges.
This marks the first official recognition for PhyEcoSyS Pvt. Ltd., an environmental R&D and consulting company led by Dr. Jasmin K.A, focused on microalgae-driven solutions, ecological design, and circular water systems. The project has been featured among a select group of field-tested models now accessible to communities, practitioners, and governments worldwide.
What Is the Floating Bio-Island Project About?
This project introduces an eco-friendly and affordable method to clean polluted rivers, lakes, and canals, without the use of expensive machines or chemicals. The core innovation lies in floating islands, created using upcycled plastic boats, barrels, or tanks, filled with fast-growing aquatic plants like duckweed and beneficial microalgae.
As water slowly flows through these modular units, the plants naturally absorb harmful nutrients such as nitrogen and phosphorus, functioning as living biofilters. The result is improved water quality, reduced algal blooms, enhanced oxygen levels, and the return of healthy aquatic ecosystems.
Environmental Benefits
Natural Water Cleaning: Algae and plants soak up pollutants and heavy metals, mimicking the filtration functions of wetlands.
Biodiversity Support: Floating roots create microhabitats for fish, insects, and other aquatic life.
Mosquito Control: Gentle water movement reduces breeding grounds, helping prevent vector-borne diseases.
Carbon Capture: Microalgae and plants absorb CO₂, contributing to local climate action.
Erosion Reduction: Islands buffer wave action and protect fragile riverbanks from degradation.
Economic & Social Benefits
Ultra-Low-Cost Deployment: Each unit can be assembled for as little as $10–20 using locally available recycled materials.
Green Livelihoods: Communities, schools, or NGOs can build and maintain the islands, generating local jobs and skills training.
Biomass Reuse: The harvested plants and algae can be:
Converted into biochar to enrich soil
Used as animal feed or compost
Processed into biogas or biofuels for clean energy
Educational Value: Floating islands serve as living laboratories for schools and citizen science programs.
CSR Ready: Businesses can sponsor units for environmental branding under their Corporate Social Responsibility (CSR) commitments.
How It Works
Each island is constructed using repurposed plastic containers with perforations to allow water flow. Selected aquatic plants and microalgae are cultivated inside. As water passes through, these organisms absorb nutrients and trap pollutants, storing them in their biomass. Harvesting is done every few weeks, and the plants are either reused or repurposed.
The system is passive, solar-independent, and low-maintenance, making it suitable for a wide range of applications—from city canals to remote rural ponds.
This Recognition Matters
Waste Free '23 is an international initiative making significant impact across 30 cities in 11 countries, with over:
14,000+ homes made waste-free
6,853 tons of waste diverted from landfills or incineration
645 livelihoods created
7,900+ citizens engaged in sustainability education
Our inclusion in this network validates the real-world applicability and scalability of the Floating Bio-Island—especially in regions seeking decentralized, low-cost, and inclusive sanitation models.
Looking Ahead
This recognition energizes our efforts to transform wastewater into opportunity using biology, community participation, and circular thinking. We are actively exploring partnerships with governments, CSR funders, NGOs, and educational institutions to deploy these units at scale.
If you’re working at the intersection of climate, water, equity, and innovation—we invite you to connect.
Let’s regenerate ecosystems and empower communities—one floating island at a time.
