The constant concern with the environment motivated the installation of a modern biological system of water and effluent treatment, aiming at the full reuse of the water used in the production processes. This was one of the reasons why the tannery obtained the Silver Seal in accordance with the Environmental Protocol of the English LWG (Leather Working Group), which encourages the adoption of best practices and establishes guidelines on the environmental responsibility of tanneries and their performance.
The Protocol is composed of several sections such as material traceability, energy and water consumption, production processes, waste management, effluents, emissions, licenses and restrictive substances, among others. The tannery is evaluated by applying the best practices in each section, which results in the final score. A. Bühler does not measure efforts to implement continuous improvements that result in ever better scores in the environmental protocol and will continue to work as an environmentally responsible company as sustainability is a valuable principle for the A. Bühler family.
