Proven sustainability – for over 40 years.

Since the company was established back in 1973, the principles of responsible and sustainable activity have been firmly rooted in RATIONAL. Our contribution to sustainability begins right from product development. All iCombi Pro models are ENERGY STAR certified. ENERGY STAR is one of the few globally recognized certifications for high-energy efficiency, certified by independent institutes. We also work in close collaboration with universities to find solutions that save on resources.

Our commitment is reflected in our environmentally certified production; energy-efficient sales logistics; intelligent, low-energy, efficient buildings; regularly reviewed eco-audit according to DIN ISO 14001; and our return and recycling program for our old appliances.

This makes RATIONAL a pioneer in sustainability for our entire industry.

Significant reduction in resource footprint.

Our multi-functional cooking appliances contribute enormously to reducing the energy and resource footprint in industrial kitchens. This is underpinned by the project commissioned by the Zurich University of Applied Sciences:

"34 % less electricity and 53 % less water consumption with a choice are all arguments for the use of multi-functional cooking appliances in professional kitchens".

With RATIONAL cooking technology, you save on energy, water and raw ingredients and produce significantly less waste. This innovative cooking technology delivers maximum flexibility and power and meets the highest standards in cooking quality.

The results of the resource consumption analysis based on a before-after comparison speak for themselves: The cheapest form of energy is energy that we do not consume.

International certified.

We passionately care about the enviroment.

Sustainable management is part of our daily routine, even in ecological view. We therefore continually review our energy and raw material consumption. In addition we have committed ourselves to meet the demands of the following ISO standards:

  • Quality management system: since 1996 according to ISO 9001
    We constantly improve our quality, streamline our processes and make them more efficient.
  • Environmental management system: since 2010 according to ISO 14001
    We constantly reduce our emissions and waste in order to be even more environmentally-friendly.
  • Energy management system: since 2016 according to ISO 50001
    We continuously improve our energy efficiency.

"Sustainable business and taking on responsibility for society have been integral elements of our business and production processes since the foundation of RATIONAL."
