Obtaining pure streams of materials that can be sold on at a higher value is the lifeblood of most recyclers. Pellenc Selective Technologies claims to be the market leader for sorting equipment within the European PET recycling market. According to the company, nearly three-quarters of plastics recyclers in continental Europe are equipped with its machines. Its core business is concentrated on saleable materials recovery, energy generation, biomass production and biological materials purification.
Pellenc ST, with headquarters in Pertuis, France, has been in existence for nearly a decade, and says that its machines and recycling solutions are now present in 40 countries. It has formed subsidiaries in Spain and
Japan. Around 70% of Pellenc’s production is exported, and the organisation recently celebrated its 500th installation.

And Pellenc says it is now finding new markets, with its machines working successfully in the areas of municipal solid waste (MSW), construction and industrial waste treatment, where there is an increasing need for residual waste streams to be accurately processed and separated to reclaim greater volumes of reusable material orextract contaminants with more precision.
These applications not only increase the saleable product quantities and quality of materials, but are also making significant contributions towards reducing the amount of material sent to landfill. Pellenc says its customers are able to see “the economical and environmental benefits that are a direct result of these processes”, providing the added value to “customers who invest in this state-of-the-art technology”.
It sees the MSW, C&D and refuse-derived fuel (RDF) markets as areas of opportunity for sorting specialists. Acompany spokeswoman says: “The development of sorting technologies aimed at such fields will ensurecontinuing success and growth for Pellenc, where recyclers strive to improve and refine their processes for evenbetter quality, improved recovery rates and reduced landfill tipping.”
A closer look at sorting technologies
Pellenc ST claims it has taken commingled waste sorting equipment “to a new level” with a comprehensive rangeof high-tech sorting machines that analyse, recognise, separate and eject selected recyclables or contaminantsfrom mixed municipal, construction, industrial, packaging and domestic waste.
Using advanced techniques such as spectroscopy, multi-spectral vision scanning, infrared and induction, Pellencsays its equipment “sorts and separates at a new level of speed and efficiency, purity and selectiveness”.
A Pellenc sorting machine has been developed for virtually every application ,and the process recognises andseparates polymers, cardboard, plastics, PET, WEEE or contaminants in RDF and secondary metals. It also hasmachines designed to enhance the value of C&I and MSW streams.
There are further technical options that allow the processing of difficult materials such as PETG, plastic labels and multiple layering. Target materials are ejected into bins via airflow or ballistic separation. And in many Pellenc installations, a number of units work in tandem to produce specific levels of separation and end-product purity.
Pellenc ST says its products are designed to sort by different methods for different results, whether it be bycolour, material type, fraction or recognised contaminants.
The new Boreas range utilises mid-infrared detection to sort paper and cardboard by analysing paper quality anddetecting grammage and fibre length. This allows specialist recyclers, mills or packaging companies to purifywaste paper streams, separate for de-inking and sort paper from cardboard, whatever the colour.
The recently launched Mistral range is specifically aimed at wood waste treatment, sorting and separating woodqualities to ensure an end-product suitable for board manufacture or biomass for energy generation.
