Real-Time Riverine Plastic Waste Detection Using an Enhanced YOLO Framework
AI summary Read the abstract
Researchers built an AI tool that can automatically spot plastic waste in rivers with about 95% accuracy, using smart camera technology similar to what's used in self-driving cars. This matters because plastic trash in rivers eventually breaks down into microplastics that can end up in our drinking water and food supply—catching it early and tracking pollution hotspots could help communities clean up waterways before that happens.
The accumulation of plastic waste in riverine ecosystems poses severe environmental and ecological threats, necessitating real-time monitoring solutions. This research introduces a novel framework for detecting riverine plastic waste using an enhanced YOLOv8 object detection model. The methodology incorporates a meticulously designed dataset preparation pipeline, leveraging XML annotations converted to YOLO format, and a custom training loop optimized for aquatic environments. Key innovations include advanced hyperparameter tuning strategies, integration of per-epoch performance metrics, and detailed visualizations to analyze model behavior. The dataset preparation process ensures robust training by splitting data into train, validation, and test sets, while annotations are normalized for compatibility with YOLOv8. The system was trained on a diverse dataset using an NVIDIA RTX 3060 GPU, achieving a detection accuracy of 94.6 % with significant improvements in precision, recall, and mean average precision (mAP). Results demonstrate the model's robustness across varying environmental conditions, supported by comprehensive reporting mechanisms that include per-class analysis, F1 score evaluations, and precision-recall curves. Additionally, the study provides insights into ground truth versus predictions, enabling detailed performance analysis across classes. This work contributes to the growing field of AI-driven environmental monitoring, offering a scalable and efficient solution for addressing plastic waste pollution in riverine ecosystems while paving the way for future advancements in realtime waste detection technologies.

Ocean and River Plastic Waste Detection Using Computer Vision
AI summary Read the abstract
Millions of tons of plastic pour into our oceans every year, much of it carried by rivers—but tracking where it comes from has always relied on slow, manual surveys. This study built an AI camera system that automatically spots and counts floating plastic waste from drone and shoreline footage with over 91% accuracy, offering a faster way to find pollution hotspots. Better tracking matters because plastic waste that lingers in waterways breaks down into microplastics, which end up in the fish and water we consume, making tools like this useful for guiding cleanup efforts before pollution reaches our food and water supply.
Designing Realtime Object Detection Based Plastic Litter Monitoring System
AI summary Read the abstract
Researchers built an automated camera system that uses AI to detect and count plastic waste floating in rivers, offering a faster alternative to the current method in Indonesia, which relies on people manually watching and counting debris. This matters because rivers are a major pathway for plastic pollution into the ocean, and better tracking tools can help pinpoint pollution sources and guide cleanup efforts before the plastic breaks down into microplastics that contaminate water, food, and potentially our bodies. While the AI system slightly undercounted debris compared to human observers, it offers the advantage of continuous, real-time monitoring that isn't practical
Multi-Scale Hierarchical Attention Ensemble Network for Fine-Grained Riverine Waste Segmentation Using UAV Multispectral Imagery
AI summary Read the abstract
Researchers used a drone with a special five-band camera to fly over a river in Indonesia and trained an AI system to automatically spot and map plastic waste floating in the water, even distinguishing it from natural debris like leaves and branches. This matters because rivers are a major pathway for plastic to reach oceans and break down into microplastics, which can end up in our food and water; better, faster detection tools like this could help communities target cleanup efforts before waste spreads further. The study is an early proof-of-concept from one river during one season, so more testing is needed before it can be used widely.

AI summary Read the abstract
Scientists built an AI-powered camera system that can automatically spot trash and pollution—like plastic, oil, and foam—floating in rivers, then instantly alert cleanup crews to the exact location. This matters because polluted rivers often feed into drinking water supplies and can carry microplastics and toxins that harm human health, so catching pollution faster means it can be cleaned up before it spreads further into the water we rely on.

AI summary Read the abstract
Scientists developed a faster, more accurate AI tool to detect and count tiny plastic particles (microplastics) in water samples. This matters because microplastics are showing up everywhere, including our drinking water, and better detection tools help researchers track this pollution more efficiently, which is a key step toward understanding its health risks and creating solutions to reduce our exposure.
