How Catharina Rapchan and Aruanã.ai Are Turning Technology Into a voice for Nature
At just 17 years old, Catharina Rapchan stands at the intersection of youth, innovation, and environmental action — leading a project that’s redefining what sustainable technology can be.
Her initiative, Aruanã.ai, is more than a tech startup; it’s a new way of thinking about how artificial intelligence and human empathy can coexist for the good of the planet.

A Generation That Thinks Differently
While most teenagers are still deciding what to study, Catharina is already shaping the conversation around the future of environmental technology.
Inspired by the urgent need to protect Brazil’s rich ecosystems — from coastal zones to tropical forests — she envisioned AI systems that don’t just observe the environment, but understand it.
“I wanted to show that technology doesn’t have to compete with nature,” she says with a smile at the COP30 Green Zone in Belém. “It can listen to nature, learn from it, and act to protect it.”
Artificial Intelligence With Purpose
At the core of Aruanã.ai lies a sophisticated combination of Artificial Intelligence and visual-acoustic analytics.
Through a network of intelligent monitoring units — equipped with cameras, microphones, and environmental sensors — the system can detect and interpret patterns in the natural world:
sounds of chainsaws or vehicles in restricted areas, the presence of wildlife, early signs of fire, or illegal dumping.
The data collected is processed in energy-efficient datacenters powered by NVIDIA-based AI hardware, designed to minimize power consumption while delivering high-performance analytics.
Instead of relying on centralized cloud infrastructure, Aruanã.ai deploys localized “edge datacenters”, strategically placed near renewable-energy sources to reduce transmission losses and environmental impact.
Blockchain, Trust, and Transparency
But the real breakthrough comes from how Blockchain technology is used.
Every analyzed frame, sound, and event is digitally signed and timestamped on a blockchain ledger, ensuring transparency, authenticity, and traceability.
This allows environmental authorities, NGOs, and citizens to verify that what they see in reports truly happened — a critical step in combating misinformation and greenwashing.
Blockchain also enables a token-based incentive system, encouraging citizens to participate in environmental monitoring.
When people report environmental data or engage in verified actions, they receive digital tokens — an innovative model that transforms sustainability into a shared economy of care.
Technology That Empowers People
For Catharina, sustainability isn’t just a technical challenge — it’s a human one.
Aruanã.ai is built around ESG principles (Environmental, Social, and Governance) and community engagement.
“Technology alone can’t save the planet,” she explains. “We need people to believe they’re part of something bigger — that their small actions matter when connected through intelligent systems.”

The platform connects with schools, universities, and local governments to promote education and awareness, transforming every user into a potential environmental guardian.
The project’s Aruanã Echo initiative, for instance, uses smart listening devices in forests to detect unusual sounds — such as chainsaws or fires — and alert monitoring teams instantly, often triggering drone or satellite support for verification.
A Greener Kind of Intelligence
Unlike conventional data centers that consume vast amounts of energy, Aruanã.ai’s LocalDC infrastructure focuses on efficiency and sustainability.
By processing AI workloads close to the source of renewable energy, the system reduces its carbon footprint dramatically.
This decentralized model also enhances resilience — each edge datacenter can operate autonomously, ensuring continuous protection even in remote regions.
“It’s about building intelligence that doesn’t drain the planet,” Catharina says. “Our goal is to make every byte of data part of a positive cycle — energy, information, and action working together for sustainability.”
A Vision That Inspires
At COP30, visitors are often surprised to learn that the young woman behind this ambitious initiative is still in high school.
But Catharina carries herself with quiet confidence, speaking with the clarity of someone who has already found her purpose.
Her message resonates deeply with audiences from around the world: that innovation and empathy must evolve together, and that the next generation is ready to lead this transformation.
“I think of technology as a language,” she says. “And I want it to be a language that nature understands.”
About Aruanã.ai
Aruanã.ai is an environmental intelligence platform that combines AI, Blockchain, and sustainable datacenter infrastructure to monitor and protect natural ecosystems.
Developed within the LocalDC ecosystem, it operates across coastal, forest, and urban zones — analyzing video, sound, and environmental data to generate actionable insights for public safety, biodiversity, and ESG strategies.
