Circular Services expands Greyparrot AI sorting pilot at Brooklyn plant

Circular Services is scaling up a pilot of Greyparrot's Analyzer AI camera-sorting software at its Sunset Park materials recovery facility in Brooklyn, first installed in the first quarter of 2026. Greyparrot's monitoring found 89% of aluminium passing through the site is recoverable, equivalent to about 91,000 cans a day. The two companies plan joint projects this autumn that could extend the technology across Circular Services' 38-facility network.

Why this mattersAI-based sorting could lift aluminium can recovery rates from decades-low levels, improving feedstock supply for can makers reliant on recycled metal.

  • Circular Services installed Greyparrot's Analyzer AI at its Sunset Park MRF in Brooklyn in Q1 2026, its first such deployment.
  • Greyparrot's monitoring found 89% of aluminium at the facility is recoverable, about 91,000 cans per day.
  • Circular Services operates a portfolio of 38 MRFs; the pilot could expand across the network.
  • Greyparrot raised a $27m Series B round in July 2026 led by investor Omar Mir.
  • Greyparrot says its systems have identified over $2.5bn in recoverable value across client MRFs as of July 2026.
