Agricultural & Horticultural applications
Grow crops,
not plastic waste.
And we know how to do that!
With Caleyda®
Use it, grow with it and leave it.
Many temporary products used in greenhouses, tree nurseries, and agriculture are made from conventional plastics that persist long after use or cost money to remove. Caleyda® offers a biodegradable alternative with good performance, and is suitable for composting, anaerobic digestion (together with green waste), or biodegradation in soil (tree binders, nursery pots etc.), helping to prevent the accumulation of persistent plastic residues in compost, water or soil.
Cost Efficiency
Reduce your waste management costs
Sustainable Sourcing
Renewable, locally sourced materials

Why Controlled-Release Fertilizers Need Caleyda®
Remy Jongboom explains why Caleyda®, produced from organic residual streams, is an excellent material choice. Caleyda® helps you save costs, source more sustainably and operate more efficiently.
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.
Processing methods
Innovative processing methods for biodegradable biopolymers
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.
