Sustainability goes beyond the product

As a member of the GRAF Group, the trade brand 4rain has been born with a careful use of water resources, the avoidance of environmental damage and the responsible treatment of people and nature from the very beginning. Our products are manufactured in an extremely resource-efficient way.


75 % recycled content
100.000 t LESS CO² emissions through recycling - equivalent to the CO² emissions of 60,000 cars
Recycled material

80 % renewable energy share used in production

State-of-the-art production facilities for LOW ENERGY CONSUMPTION




Efficient production thanks to modern facilities

Sustainability is the top priority in our manufacturing processes. The residual heat from production is used to heat the production- and logistics buildings. Closed water cycles ensure that our production uses as little water as possible. In our factories, rainwater is also used for cooling and cleaning processes.


Further measures to reduce our energy requirements

  • Energy mix with 80% renewable energies
  • Energy management according to ISO 50001
  • Saving heating energy through heat recovery
  • Minimal water consumption thanks to closed cooling circuits
  • Rainwater utilisation for cooling and cleaning processes, toilets, washing machines
  • Universal use of LED lighting
  • Infiltration of excess storm water runoff
  • Further sustainability measures on water protection and noise emissions
  • Optimised logistics between our factories


Competence Centre for Raw Materials

70% of all 4rain products are made from Upcyclen. This material is produced in the GRAF Competence Centre for Raw Materials, for example from plastic waste from the yellow bag. This means that disposable packaging is turned into long-lasting environmental products. The Competence Centre combines multiple process steps with new plant technologies to form an integrated process chain. Its pioneering technology makes the plant the only one of its kind in the world. With this, we make an important contribution to the recycling of plastic waste.

With our innovative ideas, we also convinced the Federal German Ministry of Economics and Technology. The Federal Government supported the project as part of the Environmental Innovation Programme, which aims to promote the use of new technologies and the setting up of production plants that can serve as role models.



We save CO² emissions from over 60,000 cars

The consistent use of recycled raw materials saves 100,000 t of CO2 emissions per year compared to the use of new raw materials. This corresponds to the emissions produced by more than 60,000 passenger cars.


Extremely durable and fully recyclable

The service life of our high-quality products spans generations. In the long run, this ensures that fewer resources are required, which minimises the environmental impact. Right from the product development process, 4rain attaches great importance to sustainable product design. The supply of spare parts for our products is guaranteed over a long period of time. At the end of their life cycle, 4rain products are 100% recyclable.


Rainwater harvesting conserves our groundwater ressources


Water is the medium that makes climate change tangible for all of us. There is no water shortage in Germany yet, but groundwater levels are already falling across the country. Today, Graf customers worldwide already save 208 million litres of drinking water every day, as much as the daily demand of the city of Munich.



Save up to 50 %

On average, every German citizen consumes 130L of drinking water per day. Small steps are all it takes to make a positive change in your water footprint. With products from GRAF, up to 50 % of drinking water in private households can be replaced by rainwater.


Rainwater is precious

Plants love rainwater. It is naturally soft and lime-free. This means that laundry washed with rainwater will be fresh and clean whilst using significantly less detergent. You can also save on additional descalers. There is also less scale build-up in the toilet.


Infiltration or retention as a supplement

Often, infiltration or retention of rainwater on the property is a requirement for new buildings. This can be easily implemented with 4rain retention tanks or infiltration systems. This is a simple way to meet official requirements and also save on rainwater charges. Incidentally, both options can be easily combined with rainwater harvesting.
