our responsibility


We know we have a responsibility – and we take that responsibility seriously. To get better we work hard. For example, we have developed a washing machine that degreases metal components with steam instead of strong chemicals. Not only does this protect the employees in production, it also protects the environment.

Better infrastructure

The infrastructure is important to improve conditions for the locals. Therefore, we do what we can to improve these conditions with both financial, technological and technical means and support.


We ensure that all our employees receive a fair wage. The salary level is given according to work tasks and not gender. This is not a matter of course in Vietnam, but for us it is not up for discussion.

More biodiversity

A lack of biodiversity is a growing problem in the world. The organisation Vild Med Vilje (Wild On Purpose) is working against this. To support a more diverse nature we sponsor the organisation.
