Eco restoration
Made to perform, designed to disappear
Performance today, nature tomorrow
Caleyda® is Made
to perform
and designed to disappear
Eco-restoration projects require materials that protect and support ecosystems during their recovery. Caleyda provides a biodegradable alternative to conventional plastics, delivering the necessary performance while avoiding long-term plastic accumulation a microplastic formation.
High manufacturability
and environmental performance.
Defined functional lifetime
and predictable biodegradation behavior
Locally produced
in the Netherlands
Remain functional
And fully biodegradable at the same time
With tuneable biodegradation rates, Caleyda can be engineered to safely remain functional for the required period and then fully biodegrade in soil, freshwater, or marine environments. This allows restoration materials to support ecosystem recovery when needed and disappear when their job is done.

Why Eco Restoration Needs Caleyda®
Eco-restoration projects require materials that protect and support ecosystems during their recovery. Caleyda provides a biodegradable alternative to conventional plastics, delivering the necessary performance while avoiding long-term plastic accumulation a microplastic formation.
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.

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.
