Biomaterials made by nature

Paques Biomaterials produces Caleyda 

a natural alternative to plastic, with all its advantages but without its disadvantages.

Microplastics pollution

Human society is addicted to plastics, consuming millions of tons per year. Plastic’s use brough prosperity due to its great mechanical and barrier properties. However, its leakage to the environment leads to accumulation of microplastics, which can nowadays be found in every corner of Earth and in most living beings, including ourselves! Its concerning effects in the environment and living organisms are now coming to light, making it urgent to tackle the microplastics pollution from growing further.

Paques Biomaterials provides a solution to microplastics

We produce Caleyda, a natural material replacement for Plastic, with the major benefit of being fully biodegradable in all Earth environments. Caleyda consists of PHA polymers  produced by natural microbes that can be used in a wide variety of applications. These polymers offer better end of life options compared to other plastics, always preventing  accumulation of microplastics in the environment.

A Circular Natural & Valuable solution!


We use wastewater and organic waste rich in organics for PHA production.


To produce PHA, we grow natural microbes that produce and accumulate PHA.


Bacterial biomass full of PHA represents a valuable source of income.
