Pioneering efficient recycling of plastics using terahertz technology

Plastic consumption has increased due to its convenience, versatility, and cost-effectiveness, but it has also led to a significant increase in plastic waste. The diverse range of plastic colors, particularly black ones, presents challenges in sorting efficiently, leading to unrecyclable mixed plastic waste and lower economic value. Near-Infrared spectroscopy struggles with black plastics due to their strong light absorption.

The main goal of this discovery project is to assess the feasibility and potential benefits of using continuous wave terahertz (THz) technology for characterizing and sorting recycled black plastics. This project aligns with RRECQ's objectives of enhancing plastic recycling and promoting the circular economy, prioritizing environmental preservation and contributes valuable insights to the scientific community and the recycling sector, advancing THz technology's use in sustainable recycling practices and improving plastic recycling efficiency.
