The Bonnau gravel works in Bobenheim-Roxheim, Rhineland-Palatinate, is an example of regional value creation and sustainable raw material extraction. The plant currently extracts around 2500 tonnes of sand and gravel every day. The Bonnau gravel works is operated by Willersinn Minerals GmbH, a subsidiary of Alois Omlor GmbH in Saarland. STICHWEH played its part in ensuring sustainable raw material extraction with state-of-the-art processing technology for precise grading and classification: from raw gravel grading, grain size classification and dewatering to stockpiling.
Philipp Rosenberg, Managing Director of the Industrial Association for Stone and Soil in Neustadt, honours the principle from the region for the region and the active contribution to biodiversity when the Bonnau gravel pit comes into effect.
