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. Whitefficiency® is our contribution to sustainability that begins right from product development. We work in close collaboration with universities to find solutions that save on resources.

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

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

Significant reduction in resource footprint.
With multi-functional cooking appliances.

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.


Sustainable management.

RATIONAL acts exclusively according to the principles of sustainable and profitable growth which is why our sustainable approach reflects ecological, economic and social aspects.
To demonstrate this continuous effort, RATIONAL is certified to ISO 14001 and is entitled to use the “Lean and Green” logo. "Lean and Green" is a cooperation between industry and consultancy which specialises in reducing the energy footprint in the processing industry. But despite all its success to date, RATIONAL still feels it has a long way to go before reaching its goal in terms of sustainable activity.


Committed to quality for school catering services.

RATIONAL is a member of the Verein Deutsches Netzwerk Schulverpflegung e.V. (DNSV), an association of companies committed to improving the quality of school catering services. In close cooperation with school authorities, teachers, caterers, parents and politicians, we address the present and future challenges involved in school catering in Germany.


United against waste.

RATIONAL supports the initiative "United Against Waste". The aim of the global initiative "United Against Waste" is to actively fight against the amount of food waste in the entire food service market and make everyone in the industry aware of the importance of the preservation and respectful use of food.
The "United Against Waste" campaign was launched in Germany in 2012. RATIONAL is one of the founding campaigners.
Our solutions to reducing overproduction in day-to-day operations, such as Finishing, play an enormous contribution: By uncoupling production and service, Finishing is used to only heat up quantities of food that are actually required.


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