Two bio-based materials.
One mission.
Greewave develops FibraQ® and RubraQ innovative materials from Swedish forestry residues for sustainable plastics and rubber.​
RubraQ: Renewable Elastomer Innovation for High-Performance Plastics
At Greewave, we are developing a new class of bio-based elastomers designed to replace fossil-derived synthetic rubbers in demanding industrial applications. Our RubraQ material is made from renewable forestry residues and aims to deliver high-performance, non-toxic alternatives to conventional rubbers like polybutadiene.
​
This patent-pending innovation builds on years of academic and industrial research, and is supported by multiple peer-reviewed publications. The material is currently undergoing lab-scale validation, with promising early results indicating strong potential as a drop-in solution in applications such as ABS and HIPS, where it can replace fossil-based rubber components.
​
While RubraQ is not yet in production, we are preparing for pilot-scale development and early customer integration. Our goal is to enable a more sustainable, circular future for the plastics and rubber industries.

FibraQ: Engineered Wood Fibre Material for Sustainable Plastics
FibraQ® is Greewave’s commercial-ready wood fibre material designed to reduce fossil content and carbon emissions in plastic products. Made from modified fibres sourced from sustainably managed Swedish forests, FibraQ enables manufacturers to create biocomposites with a lower environmental footprint.
Delivered in granulate form, FibraQ integrates seamlessly into existing compounding processes and is compatible with virgin or recycled plastics, as well as biopolymers. It supports applications in injection moulding, extrusion, 3D printing, and thermoforming.
Our demo plant in Sweden enables testing, validation, and production at up to 100 kg/h supporting customer innovation and small-scale manufacturing.
