French biotech company CARBIOS has signed a key agreement with German waste management specialist Hündgen Entsorgungs to supply CARBIOS’ upcoming polyethylene terephthalate (PET) biorecycling plant.

This marks a significant step towards CARBIOS’ first commercial plant in Longlaville, France, which is currently under construction and expected to be operational by the end of 2026.

The agreement outlines Hündgen’s commitment to supply 15,000 tonnes (t) per year of post-consumer PET flakes, sourced and processed from household light packaging waste in Germany.

This PET waste will be transformed into usable biorecycled materials through CARBIOS’ innovative enzymatic depolymerisation technology.

CARBIOS’ technology offers an advancement in PET recycling.

Unlike traditional methods, CARBIOS said it can process a wider range of PET waste, including coloured, opaque packaging, and even polyester textiles.

This translates to greater flexibility and cost-effectiveness for CARBIOS, as it is not limited to high-demand clear plastic bottles.

The Hündgen partnership secures a significant portion of the feedstock required for CARBIOS’ Longlaville plant, which will boast a processing capacity of 50,000t annually when fully operational.

This agreement comes alongside previously announced deals with Landbell Group for food trays and a successful bid for tray recycling in France.

The strategic location of the Longlaville plant, near waste sources in Belgium, Germany, and Luxembourg, further strengthens CARBIOS’ local sourcing strategy.

“Through our partnership with Hündgen, CARBIOS has now secured most of the feedstock supply for our first commercial plant. CARBIOS’ innovative biorecycling technology enables the conversion of diverse PET waste allowing more flexibility in sourcing, and price-competitiveness compared with high-demand clear bottles,” said Emmanuel Ladent, CEO of CARBIOS.

Christian Hündgen, CEO of Hündgen Entsorgungs, echoed this sentiment: “Establishing new standards in the field of plastic packaging recycling requires the development and implementation of innovative technologies and the promotion of cross-border cooperation. In this context, we are delighted to be part of one of the leading projects in Europe in the field of PET non-bottle recycling.”

The collaboration between CARBIOS and Hündgen paves the way for a more sustainable future for PET plastics, offering a wider range of recyclable materials and promoting a more circular economy.
