MGG Polymers tackled the expedition into unknown territories with strong partners. Before that, however, the company improved its own separation processes. “In some cases, a really big effort was required. For example, the technologies behind these separation steps had to be developed from scratch,” reports Günther Höggerl. The project was finally completed in 2018 - a big step forward that brought amazing results.
MGG Polymers as trendsetter
To complete the recycling of PC/ABS, the material has to be not only optimally sorted, but also compounded and granulated. In order to successfully master this step, a tailor-made extrusion line was designed in cooperation with an Austrian machine manufacturer. This line conceals important innovations - such as high-performance degassing devices, which are now increasingly used in the industry. MGG Polymers has thus set new trends, which is not surprising in view of the advantages for Höggerl: “This high-performance degassing system enables pollutants that are generated during the processing to be removed much more effectively. This also improves the odor of the finished product - which is particularly important for customers in the automotive industry”.
The system also enables the dosing of additives in their pure form. This allows the properties of the produced recycled plastic to be significantly influenced. “It is not always easy to obtain finished additive solutions for our sorted recycled plastics on the market. Therefore, we have to develop them ourselves to some extent. Thanks to our flexible plant, we can always try out a few things here,” Höggerl sees many more development opportunities.
