Environment
The Carriat Tannery strives to preserve the local natural resources.
Maintenance of our green spaces is partly managed by eco-grazing thanks to the presence of donkeys who ensure constant mowing.
The tannery is located in a remarkable countryside landscape in the heart of the French Basque Country. We protect it by not releasing any production waste into the environment. The waste is Our effluents are first treated in our own wastewater treatment plant, before being transferred to the municipal wastewater treatment plant for secondary treatment.
