Sustainable biocomposites with sunflowerseedhulls

We have sustainable materials that are refined with the fiber of sunflower seed shells.

Your benefits with Golden Compound


We have been working on the further development of our bioplastics since 2014. This know-how helps us to provide you with the best formulation for your application.

Saving resources

The sunflower seed shell is a waste product of the food industry. Its use can save valuable resources in the plastics sector.

Save energy

Our materials require less energy during processing. This saves you real money in the manufacture of your products! It also results in shorter cycle times.

Certified quality

We have our compounds certified by TÜV Austria. They are certified according to OK-Compost-Home, OK-Compost-Industrial, OK-Biodegradable-Soil and OK-Biobased.


We have a strong network to international compounders, suppliers and producers. This gives us many opportunities to respond to your customer requirements.


The main goal of our materials is to avoid waste, especially where it does not belong: in nature. That is why, in addition to recyclable GC pro, we have also developed compostable and earth-degradable GC green compounds.
