DENIOS - We protect people and the environment

Every minute a whole rubbish truck full of plastic waste ends up in our oceans! A single drop of oil contaminates 600 litres of drinking water! All this makes it clear: it is more important than ever to take care of nature and the 4 elements: Protecting water, earth and air and taming fire. This is exactly what we at DENIOS have been doing - for more than 35 years!

We are a family business, we are a global market leader and: We take responsibility - with innovative strength, sustainable action and global thinking.

DENIOS - Protection of the air

This element should also remain clean and pure: DENIOS provides innovative solutions for environmental protection thanks to clean air.


Without fire, our lives would not be what they are. It has fascinated us humans since time immemorial - it is both a life-giver and a danger. Fire gives us warmth, but it can also destroy. It gives us warm food, but it also kills life. And there are also some facts you (probably) didn't know about fire:

  • Fire needs three things to burn: a "fuel" such as wood or coal, an ignition spark and oxygen from the air.
  • Inside the sun there is a temperature of 15 million degrees
  • The hottest flame has a temperature of around 6000 degrees - it is created when certain molecules are burnt under high pressure For comparison: a candle flame reaches up to 1400 degrees at its hottest point
  • The oldest remains of a fireplace so far have been discovered by researchers in a cave in South Africa - the burnt bones and plant parts are around one million years old
  • The first fireworks were seen as early as 1000 years ago in China: bamboo canes were thrown into the fire, where they burst loudly and were supposed to drive away ghosts.


Water is the basis of all life! Streams, rivers, lakes, wetlands and oceans are the habitat of many plants and animals. Yet water is not only an elementary component of life - it is a human right. Water is a source of energy, a transport medium and a raw material - and did you already know these exciting facts about water?

  • Water is the only chemical compound that naturally occurs in all three states of aggregation: liquid as water, solid as ice and gaseous as steam.
  • About two thirds of the earth is covered with water
  • Our water consists of 97.5% salt water - only 2.5% is fresh water
  • Each of us consumes an average of just under 130 litres of drinking water per day
  • The food with the highest water consumption is cocoa: 27,000 litres are needed for one kilo of cocoa beans - only 110 litres are needed for one kilo of tomatoes.
  • The human body consists of approx. 75% water


The earth seems inexhaustible - it is simply there: under our feet, under the fields, under the grass and the trees. We stand firmly on this earth - and our soils are valuable biotopes and important CO2 donors. From Mother Earth to topsoil - here you will find more exciting facts:

  • It is 4,200 kilometres from here to the North Pole and almost 16,000 kilometres to the South Pole.
  • Our planet Earth moves around the sun at more than 100,000 km/h
  • The earth is quite heavy - it weighs 6 quadrillion tonnes (written out, this number is this big: 6,000,000,000,000,000,000 tonnes).
  • There are more organisms living in a handful of earth than there are people on the planet
  • A healthy soil takes time: the formation of a 10 cm thick layer of soil takes about 2000 years
  • The world's deepest hotel room is located in Sweden in a disused silver mine - where you stay 155 metres underground


We need it to breathe, to grow, to live. Air is invisible to us - and yet it is always there. Only the wind lets us feel that there is something there: it propels sailing ships, makes windmills move and makes balloons rise into the air. Read more exciting facts about the air here:

  • Air consists of various gases - 20 % oxygen and almost 80 % nitrogen - plus small quantities of other gases.
  • A person takes 12 to 18 breaths per minute - so in the course of our lives we breathe in the air from 14 million balloons
  • Air has a weight: 1 cubic metre of air weighs 1.3 kilos
  • According to studies, we are significantly less likely to get sick if we spend at least 30 minutes a day in the fresh air
  • Under good conditions, a single wind turbine generates enough electricity to supply 4,000 households.
  • The first hot air balloons took to the air in 1783 - as passengers a rooster, a duck and a sheep (all survived the balloon flight well!).
