The plastics industry is under increasing pressure to develop more sustainable solutions without compromising on performance and cost-effectiveness. This is where highly filled natural fibre concentrates come in! With fibre contents of up to 70%, they offer an innovative way to reduce the environmental footprint of plastic products - without compromising on processing.
Highly filled concentrates for more sustainability
Our GC pro concentrates GC pro 5545 BO and GC pro 7056 BO set new standards. They consist largely of natural fibres, specifically sunflower hulls - a valuable by-product of the food industry. These hulls are incorporated into our concentrates at high levels, up to 55-70%. The best part? They can be integrated into existing production processes like a masterbatch. This allows manufacturers full control of the final fibre content and allows them to decide how sustainable they want their end product to be.
Key to CO₂ reduction: recycling of residual materials
Sunflower hulls are produced in large quantities as a by-product of food processing and have long been considered an unused waste material. However, thanks to innovative material development, they can now be put to good use. Their use in our concentrates helps to conserve fossil fuels and significantly improves the environmental performance of our products. With a CO₂ value of only 0.88 kg CO₂/kg GC per 5545 BO and only 0.74 kg CO₂/kg GC per 7056 BO, they offer a sustainable alternative to conventional plastics.
Why sunflower seed shells? The advantages at a glance:
✅ Effective use of residues: Sunflower hulls are a renewable resource that does not require additional agricultural land.
✅ High natural fibre content: With up to 50-70% natural fibre, the concentrates make a significant contribution to CO₂ reduction.
✅ Optimised processing properties: Sunflower seed hulls improve flow and dimensional stability during processing.
✅ Flexibility in the production process: the content of natural fibres can be adjusted according to requirements by means of individual dosing.
✅ Processable with standard technologies: No need to modify production systems - concentrates can be integrated directly into existing injection moulding processes.
✅ Sustainability without compromise: improved environmental performance without compromise to mechanical properties.
How do I get started?
Quite simply, the concentrates are added directly to the polymer (PP Copo) - similar to a masterbatch. The dosage determines the final natural fibre content, allowing maximum flexibility. Whether packaging, technical components or household products, the modular approach allows a wide range of applications.
Conclusion: sustainability meets individuality
Highly filled natural fibre concentrates with sunflower seed hulls are a real innovation for the plastics industry. They enable sustainable production without compromising on processability and performance. If you are looking for flexible and environmentally friendly material solutions, GC pro 5545 BO and GC pro 7056 BO are the right choice.
