The efficient use of water for the production of leather sets a high standard. The needed amount of water per m² of finished leather accounts for rohgly one third of the otherwise customary demands. The average consumption was continuously reduced in the last years through multiple use and through the optimisation of the water utilization.


High legal and permission related requirements apply for us as a direct discharger into the river Weser. Our own waste water treatment plant enforces them exemplarily. The discharge values are fully in accordance to the minimum requirements set in Annex 25 of the Waste Water Ordinance. HELLER-LEDER has reduced for some Declarable Values the parameters and overfulfils the required cleaning duties.
