Biffa Aldridge

Pellenc ST supports Biffa to double recycling capacity with Mistral+ CONNECT

Waste management company Biffa, one of UK leaders in closed-loop plastic recycling, has doubled the plastic recycling capacity at its Aldridge materials recycling facility (MRF) in the West Midlands.

Built in 2008, Biffa’s Aldridge MRF diverted 300,000 tonnes of waste a year from landfill by turning it into saleable commodities. In addition to plastic bottles and containers, the facility can process aluminium and steel cans, as well as glass bottles and jars from a household recycling stream.

To increase its recycling capacities, Biffa partnering with Turmec decided to upgrade its plastic bottle sorting line and install latest generation Pellenc ST Optical Sorters for higher material recovery and recycling.

Doubling the amount of materials, we can recycle at one of the country’s largest plastic recycling facilities (PRFs) is helping to support targets to recycle more and enable the UK circular economy.”

Chief Operating Officer for the Recourses and Energy Division at Biffa

3 Mistral + Connect optical sorters are now in operation to recover recycled plastic and optimise the purity of sorted materials.

The Pellenc ST sorters increase the recovery of following target fractions:

Clear and light blue PET

Coloured PET (Jazz PET)


Aluminium and Steel cans

Glass Bottles and Jars

With these advanced technologies, Pellenc ST optical sorters improve single-layer PET trays separation from PET bottles and remove multilayer food trays to produce a high-grade PET bottle stream.

All plastic grades from the Aldridge facility will be used to feed Biffa’s new and existing polymer’s facilities and particularly for Biffa’s £27.5 million Seaham facility (plant is also equipped with Pellenc ST machines).

Biffa Aldridge was the first plant in the UK to benefit from the last generation of Pellenc ST machines: the Mistral+ CONNECT.

Equipped with the latest generation of detection technologies, this new Mistral+ stands above other sorting machines with an unmatched sorting performance. The new “FLOW Detection” system combines a new spectrometer covering an extended NIR/VIS spectrum, as well as focused lighting. This combination enables recovery of target materials with very high levels of purity.

Another key point, this new version guarantees long term adaptability with the integration of future technologies implemented in the form of simple upgrades.

Finally, as its name suggests Pellenc ST includes a series of sensors on all the Full Package models as well as offering services that can be used remotely or on-site. These different sensors collect additional information to log and analyse equipment incidents, avoid breakages or blockages, and analyse the composition and distribution of materials processed by the equipment. This data enables operators, in collaboration with Pellenc ST experts, to better target corrective actions to optimise the availability rates of the site as well as the sorting quality.

  • New multi-stream spectrometer
  • Focused light for a more accurate signal
  • Complete coverage of NIR/VIS spectra with a unique spectrometer
  • Optimised Electronics for a better signal/noise ratio
