How are recycling robots using AI to improve waste management? The scale of the task means that manual sorting is slow, costly, and inefficient. However, thanks to technological advances, everything we discard—and that used to end up abandoned in landfills—can now be identified, selected, sorted, and analysed at high speed and with great precision, thanks to optical sorters and recycling robots, ...
For example, with textile waste, we use artificial vision, which captures and analyzes real-life images, combined with near-infrared spectroscopy (NIR) to identify composition. This technology, mainly represented by our ECOSORT TEXTIL, enables the administration of thousands of tons of textiles annually. For glass, the ECOGLASS optical separator classifies and ...
Optical and Physical Properties of UCNPs The luminescence of UCNPs originates from the step-by-step energy level transition of lanthanide ions. For example, after Yb³⁺ absorbs NIR photons (980nm), it excites Er³⁺ (emitting green light, 550nm) or Tm³⁺ (emitting blue light, 450nm) through energy transfer, and finally emits visible light through the anti-Stokes effect. By adjusting ...
Cut waste, catch problems early, and hit quality targets—biofuel producers use Fourier transform near-infrared (FT-NIR) spectroscopy to make that happen. This real-time tool measures key chemical properties in ethanol, biodiesel, and renewable diesel as production runs. FT-NIR keeps operations tight by tracking critical variables without ...
Upconverting nanoparticles (UCNPs) break through the traditional Stokes limit and achieve "anti-Stokes luminescence" by absorbing low-energy near-infrared photons and emitting high-energy visible/ultraviolet photons. This feature makes it show revolutionary potential in the fields of biomedicine and energy, especially in deep tissue penetration and low background noise. High quantum yield UCNPs ...
