The environment & CSR

Dan-How ensures the most environmentally friendly perforation and production in the industry!

At Dan-How, we focus on taking care of the environment and society. Below you can read more about what measures we take. You can also contact us and hear more.


Our environmentally friendly initiatives

Collection of waste material

Through our daily cleaning, we make sure to collect all waste material – including all the holes!

Recycling of the material

Our internal cleaning and sorting system ensures that all waste materials are sorted and distributed for optimal recycling. As a result, we currently send approximately 99% of all waste material from production on for recycling.

Recycling of packaging material

We recycle the packaging in which the products are shipped. This means that the perforated material after completion of processing is packed in the same packaging as the material was shipped in originally.

Eco-friendly products

All lubricants used in the manufacturing processes are among the cleanest emulsions on the market.

100% sustainable energy

All production takes place mainly using wind turbine energy! And if it is windless one day, then the power is supplied from hydropower or solar power plants.

Sturdy tools

As we are responsible for the construction and maintenance of all perforation tools, the service life of these is optimized and extended before they can be discarded and sent for steel recycling.

HAUFE-Deckensysteme GmbH-Tyskland
Als Hersteller von Deckensystemen arbeiten wir seit gut 10 Jahren mit der Firma Dan-How eng zusammen,
die für uns die Bänder unserer Lamellendecken mikroperforiert. Um die Qualität unserer Systeme auf einem
gleichbleibenden hohen Niveau zu halten ist es für uns wichtig, dass der vereinbarte Qualitätsanspruch an
Lochung und Richtqualität verbindlich eingehalten wird. Ebenso müssen wir durch die Objektarbeit Liefertermine
verbindlich einhalten und oft auch sehr kurzfristige Lieferungen realisieren. Die Firma Dan How hat uns hier immer
voll unterstützt und stehts pünktlich die geforderte Qualität geliefert. Wir schätzen diese Zuverlässigkeit und die
immer freundliche Zusammenarbeit, auf die wir hoffentlich auch zukünftig setzen können. Herzlichen Dank
vom gesamten Team der HAUFE Deckensysteme GmbH.
