Label Date May 22, 2018
From France
Maturity stage TRL 9 / CRI 5-6 - Market competition driving widespread deployment &/"Bankable" grade asset class

Combining infrared, visible spectroscopy and induction, Pellenc ST separates complex materials that could not otherwise be identified by the human eye and enables considerable amounts of recyclable materials to be diverted from non-sustainable end-points such as landfills, energy recovery or exports to countries with lower standards. The automated high-speed conveyor belt combined with real-time software treatment enable processing of large volumes of waste at rates unachievable by conventional picking methods.

The Environmental Benefits

  • A versatile and upgradable solution able to keep pace with new materials , ensuring a long life-cycle of the equipment.
  • Efficient and able to meet industrial requirements. Better recycling rates minimize negative plastic impacts on the environment.
  • A complete solution to support industrials and optimize their recycling processes.
  • Automation betters working conditions (less musculoskeletal disorders), and skill level of manual sorters (now quality controllers).

The Financial Benefits

  • High quality sorting enables to sell rPET from 800$/t to 1,240$/t, reducing the price gap between recycled and virgin materials.
  • Increased sorted volumes and higher recycling yields drop landfill taxes.
  • Locally sourced and produced materials allow for easy maintenance and job creation in the region.
  • High-quality sorting helps enhance industrials’ as well as consumers’ confidence in recycled products, which is crucial to trigger the virtuous circle.
