The success story
    DIENES solar system contributes to CO2 savings of approx. 45 t CO2 per year.
    DIENES Green - Nachhaltigkeit für die Umwelt

    As a family business, we at DIENES think in terms of generations. Sustainability and consideration for our environment and resource consumption are part of our DNA. Even 50 years ago, the waste heat from the hardening shop was reused for heating. In the last 25 years alone, the knife consumption of many customers has at least halved while production volumes have increased. Traditionally, our products can be disposed of or recycled after the end of their service life.

    • CO2 savings of approx. 45 t CO2 per year.
    • Basic heating demand of approx. 290,000 kW/h and at the same time 140,000 kWh of electricity is fed into the grid.
    • At our e-charging stations, you and our employees can charge the battery of your electric vehicle.
    • Sustainability is important to us: The waste heat from the compressed air supply is used directly for heating purposes.

    The traditional company DIENES

    Focusing on the customer right from the start: The traditional company DIENES was founded by Karl Rudolf Dienes in Remscheid in 1913. And even then, the goal was to adapt the cutting products and developments exactly to the customer’s requirements. This is how he laid the foundation for a globally successful development: the company, which is now in its third generation and is managed by Bernd and Rudolf Supe-Dienes

    is today the world’s leading precision supplier in the fields of knives, knife holders, cutting systems for industrial applications and the innovation partner for plate valves and regulators. From the company headquarters in Overath near Cologne, almost 500 employees are now coordinated in several worldwide locations in Germany, the USA, Asia, Poland and France.
