BUCHEN is a professional partner to foundries that manufacture moulded parts using the cold-box process
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.
Foundry operations utilise amines as catalysts for hardening the moulding-sand binding mixture. The released gaseous amines are extracted and bound with wash concentrate. BUCHEN transports the spent wash concentrate to the amine recycling installation and converts it back to amines of sufficient purity to enable them to be utilised again via the foundry supplier industry.
In collaboration with long-term partners, we also offer our customers: technical advice, plant maintenance (as a certified specialist in accordance with the German Water Act) along with a spare parts service
By combining inputs and outputs, we achieve closed product loops and offer our customers significant advantages:
