A trade show highlight of masterbatch manufacturer Lifocolor will be its biodegradable plant-based color concentrates. These are claimed to enable a closed-loop system for biodegradable plastics.

When it comes to long-term closed-loop recycling, it is not only the plastics that matter, but also the colorants employed. Lifocolor has developed masterbatches specifically for coloring recycled materials.

Due to the aspect of sustainability, natural fibers are interesting as reinforcements for plastics. To keep their ecological footprint as low as possible, it is advisable to use fibers from regionally grown plants.

The “perennial cup plant” is cultivated in Germany for biogas production. The fibers of the plant can be extracted from the resulting fermentation residues and subsequently used for composites.

The plastics industry has a variety of materials and technologies available for significantly reducing the ecological footprint of products. There are very few applications for which it is not possible to replace at least a portion of the fossil material with recyclates or bioplastics. Various methods, standards and software tools are available to determine what savings this can achieve.

Over past months, many in-house workflows and development processes have slowed down and also changed. Nevertheless, time has not stood still, also not in injection molding technology. The debate and development have been shaped by two themes: digitalization and the circular economy. Below are some examples of developments and projects that underpin this trend.
