Expenditure on downstream clean-up and disposal measures can be significantly reduced by the application of production-integrated processes for the economisation of raw materials and waste avoidance. In the electroplating sector, however, the in-house completion of wastewater cycles will rapidly exhaust the limits of available capacity and expertise. It would therefore seem a rational option that specific purification and treatment stages for a number of plants should be combined and undertaken by specialised external service providers.
As part of a combined research programme, this project was intended to demonstrate that, by the optimum combination of the in-house recirculation of materials and external material recycling, greater economic and ecological benefits can be achieved. In the combined operating plant considered and chemical and physical treatment installation – it was intended that existing technologies should be applied on a model basis (mobile ion exchanger systems and one-piece or membrane or electrolysis cells).
- The targeted interaction of internal primary measures with the external and centralised recycling of wastes has been fully achieved. Companies who were not involved in the project have already expressed an interest in the application of this system.
- The economic benefits of this model have been demonstrated. The benefits to the environment, while discernible, are not clearly quantifiable using the tools available.
- The fruits of this project have been published in the form of “Waste recycling guidelines”. These guidelines form the second part of the concluding report, and have been published in the specialised journal “Galvanotechnik”, volume 94 (2003), issue no. 6 to volume 95 (2004), issue no. 1. These guidelines can also be consulted on the internet at the following addresses: www.10galvaniken.de and www.dgo-online.de.
