We are the Ruhr District Institute of Hygiene

In the heart of the Ruhr area and active worldwide


In our densely populated region with more than 5 million people, hygiene is a real challenge. Drinking water supply and wastewater treatment, waste disposal and contaminated sites, product testing, and product recycling: all this requires our utmost attention. In the Ruhr region, in Europe, and also worldwide.

Our history is our mission


The founding of the Hygiene Institute at the beginning of the 20th century can be traced back to Robert Koch. When a typhus epidemic claimed many victims in Gelsenkirchen in late summer 1901, Koch demanded drastic measures to improve and monitor water quality. As early as May 1902, the newly founded Hygiene Institute began its work under the umbrella of an independent supporting association.

Competent and independent


With its ideal combination of experience, expertise, and independence, the Hygiene Institute is one of the largest and most modern institutions of its kind in Europe.

Our tradition is our commitment. You can rely on it.

Preventive environmental and health protection


The focal points of our work are the critical (environmental) issues of our time, which are crucial for our modern society. Environmental protection and consumer health protection are priority work areas of our institute. We regularly test natural resources (water, soil, air). We detect building pollutants and other contaminants. And we test products before they are launched on the market to prevent adverse effects on drinking water or food and protect people's health.

The Hyg wishes you a wonderful Christmas season and a happy year 2026
Bild weihnachtskarte2025de.jpg Christmas 2025 is approaching quickly. In light of the many social and political upheavals we have experienced this year, 2024 now seems almost like a time of calm in retrospect. Much of what we long took for granted—truth, prosperity, democracy, and peace—is increasingly being questioned. The rapid advancement of artificial intelligence embodies both promise and peril. Like Alfred Nobel’s dynamite, its impact will ultimately depend on whether it is guided by people of integrity and goodwill.

Thankfully, there are countless such people. Every day, they make small things possible, achieve quiet miracles, and remind us why this world remains worth living in—despite all challenges. In 2026, we will surely be among them again: encouraging one another, offering strength, and extending a helping hand where it is needed.

The upcoming holidays are, of course, a time for kindness, generosity, and solidarity. They are also a time for reflection—for appreciating what we have, and for holding in our thoughts those who must begin the new year in war, hardship, or poverty.

I would like to thank you sincerely for your irreplaceable work and wish you and your families a peaceful Christmas season, as well as health, hope, and every success in the year ahead.
