Maximizing Recycling Efficiency 25 • Ansys Lumerical and optiSLang were used to improve an innovative short-wave infrared (SWIR) sensing solution that autonomously identifies plastic based on its light reflection • Simulation enabled fast, accurate analysis to optimize the light reflection coupling, absorption layer, and fiber head design • The enhanced SWIR detector reduces the rate of false identification to improve the efficiency of the autonomous plastic waste sorting system • By cutting the cost of reusing plastic, the solution reduces virgin plastic use and its associated environmental impact • Recycling is not cost-competitive with producing virgin plastic because sorting plastic waste is highly labor intensive and expensive Wavelength Reflection ABS PET PS SWIR (0.9 – 1.7 m) detector stack design Fiber head design for illumination and collection of light Customer Challenge Outcome Solution
