Amines released in foundry facilities are extracted via exhaust air purification plants before being disposed of bonded to the wash concentrate containing sulphuric acid. BUCHEN UmweltService’s foundry services offer you a process that is both environmentally friendly and economical: We take the loaded wash concentrate and treat the amine it contains in our recycling plants to form a high-quality, high-purity product ready for reuse.
With this treatment, BUCHEN UmweltService creates a closed product loop that impresses in terms of both sustainability and compliance with statutory requirements. At the same time, our foundry services reduce your organisational effort to a minimum. Officially approved exceptions are applied to make the usually time-consuming implementation, documentation and verification process significantly easier. All you need is the acceptance certificate we give you at collection.
