In cooperation with the Fraunhofer Institute IVV, CreaCycle GmbH developed the CreaSolv^® Process. This "selective extraction" is based on standard process technology (patented by Fraunhofer Institute).

Proprietary CreaSolv^® Formulations dissolve selectively the target polymer and the desired polymer precipitates when a special CreaSolv^® Precipitation Formulation is added after the cleaning from impurities.

The volume of solvents used is very small in relation to the treated plastic (<1%), because the CreaSolv^® Formulation is run in a closed-circuit and routinely recycled, whereas the relatively small volume of impurities is separated and concentrated. With its energy balance this process performs very well in environmental impact assessment studies. The smallest plant has a capacity between 2-4.000 tonnes annually.

Expanded plastics like polystyrene can be collected already dissolved in special CreaSolv^® Formulations, thus achieving a higher freight density and transport cost reduction when compared to present collection systems. The dissolved plastic can be further processed and recycled immediately in the CreaSolv^® Process.
