Paint, coatings & binders
Natural chemistry, industrial performance.
And we know how to do that!
With Caleyda®
Applied with confidence, removed by nature
Caleyda can be used in paints, coatings, and binder systems to introduce renewable and biodegradable content while maintaining the functionality required during use. After application, Caleyda-based formulations can help reduce the long-term environmental impact associated with fossil-derived materials (like alkyds and acrylics) and persistent microplastics
Higher formulation flexibility
Low-temperature (below 100°C) film formation and flexible processing
Sustainable formulations
Waterborne solutions with low emissions
No persistent microplastics
can be fully metabolized in wastewater treatment systems at paper mills
The Soil-Safe Coating
Why Controlled-Release Fertilizers Need Caleyda®
Remy Jongboom explains why Caleyda® combines versatile processing, sustainable formulation and high-performance barrier properties to enable more sustainable industrial applications without compromising functionality or existing processes.
From side stream to natural material.
A new, circular chain — powered by microbes instead of oil wells.
Second generation feedstock
We start with organic residual and side streams — resources that don’t compete with the food supply.
PHAenix® technology
Natural mixed-culture microbes feed on the streams and produce PHA, stored inside their cells as PHA-X®.
Caleyda® extraction
The biopolymer is gently extracted from the biomass through the Caleyda® Extraction Process.
Back to nature
After use, Caleyda® is recycled mechanically or biologically — biodegrading without persistent microplastics.

Frequently asked questions
We let nature do the work.
During our PHAenix process, naturally occurring microbes produce a biopolymer (PHA) from organic residual streams. PHA is then used as the base for Caleyda®.
Unlike traditional plastics, this process uses no fossil resources, no genetic modification, and no harmful additives.
Caleyda® biodegrades in soil, fresh water and marine environments, as well as in industrial and home composting — without leaving persistent microplastics. Certificates follow as they are obtained.
Caleyda® is processed on standard equipment: extrusion, injection moulding, 3D printing and water-based dispersions. See our applications for examples, or contact us to discuss yours.

Our partners
Polyurethane as a coating for fertilizers needs to be replaced with a biopolymer within Europe in 2028. And we know how to do that.
At Paques Biomaterials we have developed a new generation of materials.
