Photographic processing results in large quantities of liquid effluent which is a concern for the environment. The aim of the project is to develop a multi-step process for the treatment of photographic liquid wastes, with the following characteristics and advantages:
- Treatment of all types of waste photographic chemicals Processing without producing any additional new waste Reclamation of valuable products (e.g. silver, NH3-solutions) Processing with minimal energy input by means of heat coupling. The process will require a number of regenerative, evaporation and rectification steps. However, different sectors (printing works, photographic laboratories, hospitals, PCB manufacturers, reprography shops etc.) use different solutions and chemicals. The object of this project is to realise a process suitable for all photographic chemicals.
