How a single event drove the inspiration behind DENIOS

The memory is still vivid, the first images of a disaster that will change everything are shown on television. A warehouse on the premises of the chemical company Sandoz goes up in flames and dangerous pesticides and contaminated fire-fighting water flow into the Rhine. Helmut Dennig is immediately clear: something like this must never happen again. DENIOS was founded shortly afterwards.

More than 30 years later, DENIOS has made a name for itself worldwide as a developer and manufacturer. At 25 sales locations and six production sites, it is all about the safe storage and handling of hazardous substances, operational safety in the workplace and environmental protection. Today, the family-owned company from Bad Oeynhausen in Germany advises and supplies well-known customers such as BMW, Salzgitter Flachstahl, Volkswagen, Evonik, Bayer and Bosch.

We all have a responsibility to preserve our natural habitat - for ourselves and for future generations. At DENIOS, we see it as our primary goal to constantly improve and set new standards for this purpose.

The DENIOS Story

DENIOS was founded in 1986 in Germany, when Helmut Dennig innovated the very first oil spill pallet. One day, when changing the oil in his Volkswagen, he realised the need to take responsibility for the spilt oil. In the 1980’s people were often careless about these small oil spills, yet he was aware of the greater impact on the environment. Thinking ahead, he created a prototype container for collecting the oil - which today we know as the spill pallet.

While DENIOS was inspired by nature and passionate about its protection, it was an environmental disaster that was the catalyst for our founding.

An incident at the Swiss chemical company Sandoz, one of the biggest chemical disasters in Europe, occurred in the same year. The devastating results proved there was a massive, unaddressed need for the containment of hazardous materials.

Helmut Dennig grew his simple yet effective spill pallet prototype idea into a well trusted global company specialising in hazardous material storage and work safety products for many industries.

DENIOS now has 35 locations across the globe, with 6 major manufacturing sites, where we design and produce over 500 different models of the original DENIOS spill pallet as well as over 14,000 other work safety and environmental protection products.

In 1990 we opened our US with locations across the globe - like our 100,000-square-foot engineering, sales, and manufacturing facility in Louisville, KY - we design and produce everything from the original spill pallets to large capacity chemical storage lockers and buildings.

DENIOS is the world’s leading manufacturer and supplier of products and services for HAZMAT storage, occupational environmental protection and work safety.
