Nature's solution to plastic pollution

Paques Biomaterials uses organic side streams to create a biobased and biodegradable alternative to plastic: Caleyda®

Producing PHA from side streams

We developed a technology for microbes to produce a biopolymer (PHA) from organic residual streams. PHA can be produced by bacteria in industrial wastewater, sewage sludge and solid organic side streams, such as food waste. Our technology doesn’t modify bacteria genetically and we use no fossil resources. The first full-scale plants are already under development on three different continents. This is the start of a global, new circular chain to produce a biopolymer that is naturally biodegradable in all environments without leaving harmful microplastics behind.

With Caleyda® we provide a solution to microplastics

We produce Caleyda®, a naturally biodegradable biopolymer.

Caleyda ® stands out to other biopolymers, because:

it doesn’t leave harmful microplastic behind
it doesn’t compete with food/feed production
it’s locally sourced and produced
it has tunable properties
it has a wide range of properties

A Circular Natural & Valuable solution!

Circular

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

Natural

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

Valuable

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

What people say

"Paques Biomaterials owns a highly innovative approach to retrieve the raw materials for the production of a biodegradable alternative to plastics – the solution to replace single use plastics in (amongst others) the agriculture and horticulture industry. I am very pleased to work with the professional management team of Paques Biomaterials to further develop the products and the positioning in the market."

Anne Mieke van der WerfInvest NL

"Converting organic waste into materials provides a route to a zero-waste society and can alleviate problems associated with oil-based plastics. With this development, a new raw resource for industrial biotechnology is used for the first time on a commercial scale. Me and my colleagues at Delft University of Technology gladly support the further development of the process as well new product designs based on Caleyda."
