For more than 20 years, BUCHEN has implemented a closed recycling system for amines, including the required logistics, at the Voerde site as a competent partner to the foundry industry – and is fully committed to the objectives of the recycling economy in accordance with legal requirements.

• By combining inputs and outputs, we achieve closed product loops and offer our customers significant advantages:

  • Freedom from otherwise mandatory participation in the identification process based on disposal certification for hazardous waste, which requires official verification for each waste type and place of origin
  • Freedom from the obligation to maintain electronic dispatch notes for hazardous waste; no need to participate in the electronic identification procedure for this waste
  • High flexibility in the selection of carriers, including general cargo, through liberation from the Directive on Transport Permits (TgV)
