A fresh perspective on recycling technology emerges from the latest publication by the PLASTICE project, the result of a collaboration between researchers from CIRCE and URBASER: Pedro Compais, Belén Morales, Alberto Gala, and Marta Guerrero. This study, titled “The Integration of Image Intensity and Texture for the Estimation of Particle Mass in Sorting Processes”, offers a new method that could redefine mass estimation in recycling applications.
Published in Processes (2024), the research explores an innovative image-based approach using 2D cameras and machine learning to estimate the mass of low-density materials, such as post-consumer plastic films. By combining image intensity, texture, and size measurements, this method delivers a cost-effective solution to monitor mass flow—an essential metric in recycling facilities. Impressively, the results boast a minimal error margin of just 9 g for subsamples weighing between 2 and 82 g, challenging the need for costly sensor-based systems.
The study highlights how standard cameras can transform waste management, offering an accessible, low-cost alternative to improve recycling rates and operational efficiency.
