Paques Biomaterials supplies Caleyda PHA for circular bitumen
Key highlights
- HighTechBinders licensed TNO's circular asphalt binder technology and signed an MoU and offtake agreement with Paques Biomaterials for Caleyda supply.
- Caleyda is a PHA biopolymer integrated into bitumen/asphalt as a binder to enhance mechanical properties and road durability.
- Using Caleyda sequesters about 2 kg CO2 per kg of biopolymer when incorporated into asphalt.
- This approach supports industry targets of 30% biobased content by 2030 and carbon-neutral infrastructure by 2050.

Partnership
HighTechBinders licensed TNO's circular asphalt binder technology and signed an MoU and offtake agreement with Paques Biomaterials for supply of the PHA biopolymer Caleyda.
Technology and application
Caleyda, a polyhydroxyalkanoate (PHA) biopolymer, is integrated as a functional binder in bitumen/asphalt to enhance mechanical properties and extend road durability.
Environmental impact
Incorporating Caleyda into asphalt sequesters roughly 2 kg CO2 per kg of biopolymer and replaces fossil-based binder components with bio-based materials recovered from waste streams.
Industry implications
The collaboration and technology combination enable a local-to-local circular model and support sector targets of 30% biobased content by 2030 and carbon-neutral infrastructure by 2050.
