ZERMEG
Starting point
One of the main postulates for a sustainable economy implies that industries do not generate waste or emissions. This requires so-called "zero-emission" processes, which permit complete recycling or re-use of all raw materials and energy flows that are not contained in the final product.
Challenge
The project developed a method to revamp existing galvanising plants in order to operate them with a maximum reduction of the use of chemicals and maximum recycling.
Results
ZERMEG was commissioned after the first call of the Austrian "Factory of the Tomorrow" program. ZERMEG II is the follow-up project. It could be shown that for total recycling and a serious zero-emission-concept in depth research of degreasing and pickling in galvanising companies is necessary. Additionally, ZERMEG II aims at disseminating the approach. By involving new project partners the number of applications of the method is drastically increased. At the same time the feedback from the applications renders a broader data basis. ZERMEG III creates a virtual factory of the future from the combination of the research results of different projects. This model will be used to generate real experience for managers in experimenting taking organisational and technical decisions with regard to a sustainable development.

Ecodesign comment
A maximum reduction oft the use of water and chemicals can be achieved through the improvement of the galvanising plants via processanalysis, optimization of the process parameters and processrefeeding. For example could the sulfuric acid be reduced by half through applying this method in the pickling lin of a hot dip zincing plant.
