The CreaSolv® Process

It began in 2001 with a feasibility study on the subject of "Fish-box Recycling".

In 2002 building on the promising results the CreaCycle GmbH and the Fraunhofer Institute for Process Engineering and Packaging (IVV) in Freising decided to combine their competencies in a Cooperation aimed at "Plastic/Raw-material Recycling with the CreaSolv® Process (selective extraction) with CreaSolv® Formulations.

As a result CreaCycle and Fraunhofer Institute IVV developed together the CreaSolv® Process. This "selective extraction" is based on standard process technology (patented by Fraunhofer Institute).

Proprietary CreaSolv® Formulations with the lowest risk potential possible for user and environment (ideally not to be classified according to GHS criteria) dissolve selectively the target polymer. This reduces besides the hazard also the cost for the equipment. Finally 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.

During the following years the CreaSolv® Process was tested for different plastics, valuable raw-materials and problems and modified.
