To take part in the take-back programme, contact us to coordinate logistics. The programme applies to ARCHISONIC® Felt and other non-laminated PET-based acoustic felt products that meet our return standards. A minimum return quantity of one tonne applies, with a minimum participation fee of EUR 2500, including collection arranged from your location. Based on the material details provided, we calculate the logistics cost and arrange collection once the quote has been approved. If the shipment weighs less than initially estimated, a partial refund may apply. Once received, the material is pressed if required, shredded, and sent for depolymerisation, where the PET is broken down into its original monomers, MEG and PTA, to be used again in new PET production.
