A group of Filipino students has developed an innovative autonomous device capable of cleaning rivers and canals from garbage without the need for manual intervention.
Named SeaGBin, this system employs solar energy and IoT (Internet of Things) technology to operate efficiently.
Moreover, it is integrated with a mobile application that allows real-time monitoring of multiple parameters, including:
- Device location.
- Amount of accumulated garbage.
- Weather conditions and tide level.
This solution reduces intensive manual labor and is particularly useful in urban areas where rapid expansion exceeds the capacity of sanitation systems.
Project Origins and Device Operation
SeaGBin emerged as a response to the increasing pollution in cities like Cebu, where environmental infrastructure has not been able to keep up with the pace of urbanization.
Community clean-ups and river brigade work are insufficient in the face of the increasing amount of plastic waste in water bodies.
This technological device complements these efforts with an autonomous, affordable, and sustainable system.
How It Works
- Balanced buoyancy: designed to remain partially submerged, with the collector’s mouth at water level.
- Solar-powered pumping suction: the pump generates an output flow higher than the input, decreasing the water level inside the container and creating a natural absorption that attracts floating waste.
Main Components
- ESP32 microcontroller for system management.
- Ultrasonic sensor that measures the level of accumulated garbage.
- NEO-8M GPS module for location.
- Pocket Wi-Fi for real-time data transmission.
- 300 W solar panel and 12 V gel battery, ensuring continuous operation even on cloudy days.
Technical Innovations and Performance Testing
The design was based on a recycled plastic container, optimized for resistance and buoyancy.
Additionally, a fine mesh was incorporated to filter waste while allowing water to pass through.
Among its technological novelties, highlights include:
- Solar pumping for efficient and gentle suction.
- Advanced filtration that prevents clogging.
- Electronic modules for remote operation and autonomous monitoring.
Initial tests were conducted in controlled environments, adjusting buoyancy, energy efficiency, and stability under different current conditions.
Future Plans: System Improvements and Expansion
Developers aim to enhance SeaGBin with new updates, including:
- Lithium-ion batteries or more efficient hybrid systems.
- Increased storage capacity and filters for bulky waste.
- Artificial intelligence for waste classification.
- GPS-coordinated fleet, allowing simultaneous deployments.
- Optimized solar panels with intelligent programming.
- Expansion of the mobile app, including environmental indicators and critical zone mapping.
- Collaborations with NGOs and local governments, ensuring long-term implementation.
Sustainable Technology for Cleaning Rivers
SeaGBin represents a crucial advancement in the fight against river pollution, combining automation, renewable energy, and digital connectivity to maximize its impact.
With ongoing improvements and an expansion strategy, this system could become a key tool in preserving aquatic ecosystems, contributing to a cleaner and more sustainable future.
