Researchers at Washington State University developed a system using hyperspectral imaging and convolutional neural networks to identify plastics [1]. This method distinguishes six chemically distinct plastic types while they move on conveyor belts [2]. The technology aims to reduce landfill waste by solving contamination issues in current recycling streams [1][2]. The AI-driven approach provides high accuracy in sorting materials that look similar to the human eye [2]. By automating this process, the system improves the efficiency of waste management facilities [1]. This breakthrough could lead to a more effective circular economy for global plastic consumption [2].
