The production of circuit boards by the Niedernhall-based company Würth Elektronik, has been declared an excellent example of resource efficiency by the Baden-Württemberg state government.

Franz Untersteller, Baden-Württemberg’s environment, climate and energy minister, praised the company for their use of etchant recycling during production. Etching is quite an involved chemical process that removes and regains copper during the manufacture of printed circuit boards.

The “100 Companies for Resource Efficiency” project was launched by the state agency for environmental technology and resource efficiency in 2015. Since then, a total of 100 companies have been recognised for their resource efficiency, as well as for outstanding practices regarding the use of materials and energy. In Stuttgart, State Environment Minister Franz Untersteller presented the award to Daniel Klein, Managing Director of Würth Elektronik Circuit Board Technology.

“Sustainability and environmental protection are anchored deep within our company philosophy. We work together to keep our environmental impact to a minimum. Our environmental and energy management practices complement our quality management practices,” said Klein. “We consider the award from the state government to be further incentive to continue down the path we are headed on and to optimise our workflows and con-serve resources. Alongside environmental aspects and energy efficiency, the decision to invest in the new etching production line was primarily made on a market and customer-oriented basis. We were able to achieve an improvement in production quality. The increased etching accuracy enables us to reliably produce structures smaller than 100µm. This is an-other step towards pushing the limits of miniaturisation, which is what the market is demanding,” he continued.

The “100 Companies for Resource Efficiency” project is part of the “Alli-ance for Increased Resource Efficiency,” which was introduced by the state of Baden-Württemberg and various umbrella organisations within the industry. This year’s awards ceremony, however, marked the end of the project.
