O2eco (Brazil)
Climate-Resilient Water Regeneration at Industrial Scale
Climate-Resilient Water Regeneration at Industrial Scale
The problem they solve
Industries and municipalities across Latin America face rising water scarcity, costly treatment processes, and mounting environmental pressure from poorly managed effluents. Traditional wastewater systems require high energy, chemical inputs, and expensive infrastructure, putting sustainable water management out of reach for many regions.
Their solution
O2eco combines engineered systems with nature-based technologies to deliver flexible, high-efficiency water regeneration solutions:
● Salus System: a patented dewatering and wastewater recovery technology that enables up to 95% water reuse in industrial or municipal systems.
● O2eco_TWC Blocks: nature-based water regeneration units that restore aquatic biodiversity and treat pollution at the source, even in informal or infrastructure-poor communities.
These solutions operate with low energy use, no chemicals, and minimal setup, making them adaptable to diverse industrial and public-sector environments.
Traction
● 500 million litres of water are recovered annually
● 180,000+ people benefitted across communities
● Trusted by major clients including Sabesp, Ambev, and ArcelorMittal
● Recognised among Brazil’s top innovators:
o Top 5 in the 100 Startups Ranking – Water & Sanitation (2023/2024)
o Featured in “100 Startups to Watch” (Pequenas Empresas & Grandes Negócios, 2023)
o Over 10 innovation and sustainability awards
Why they matter now
Water scarcity, climate pressures, and rising industrial demand are accelerating the need for efficient, affordable water solutions. O2eco’s hybrid model, capable of operating both within treatment plants and directly in natural water bodies. They can provide a scalable, low-carbon pathway to expand sanitation, reduce CO₂ emissions, and regenerate water ecosystems. With proven industry adoption and powerful environmental impact, O2eco is positioned to drive the next generation of sustainable water infrastructure across Latin America and beyond.
Who they are
O2eco is a Brazilian environmental technology company delivering intelligent, chemical-free wastewater and sludge treatment solutions that dramatically cut costs, water use, and CO₂ emissions. Their mission is to make water systems more efficient, circular, and climate-resilient, reducing operational costs for industries while expanding access to clean water and sanitation for underserved communities.
