PHA

PHAs are bioplastics produced naturally by bacteria. Fully biobased and biodegradable, they offer strong material performance across a wide range of applications, making them one of the most promising alternatives to conventional fossil-based plastics.

460m tonnes

Plastic generated globally each year, a figure expected to triple by 2040.

9-14m tonnes

Plastic entering our oceans every year, breaking down into persistent microplastics that contaminate our air, soil, and the marine food chain.

70%

Technically, PHA can replace up to 70% of all fossil-based plastics
Naturally produced by bacteria from renewable resources and fully biodegradable, PHAs offer a sustainable alternative with versatile material performance. Bioextrax's GMO-free, patented processes enable the scalable production of various PHAs, alongside a high-value, protein-rich coproduct. We produce two key PHA materials: PHBV, a stiff, high-performance polymer, and PHO, a softer and more flexible polymer.

PHO

PHO is a soft, flexible, and smooth biopolymer with rubbery properties. It offers excellent elasticity, toughness, and film-forming capacities, making it perfect for applications such as personal care, coatings, adhesives, chewing gums, and artificial leather, all in a fully biobased and biodegradable material. Our innovative water-based technology enables large-scale production of this amorphous PHA while maintaining sustainability at every step of the process.

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

PHBV

PHBV is one of the most widely known PHAs, a copolymer of 3-hydroxybutyrate and 3-hydroxyvalerate. It can be produced from various carbon-based raw materials and offers strong mechanical and barrier performance, making it a sustainable alternative to petroleum-based plastics such as PP, PE, PET, and PCL. Fully compatible with existing processing equipment, PHBV can be used on its own or blended with other polymers, making it suitable for a wide range of everyday products including straws, cutlery, toys, and coffee capsules but also as SPF boosters in sunscreen and as barrier coatings.

Our efficient and chemical-free extraction technology preserves the integrity of the PHA granules, enabling a stable water dispersion of our PHBV and opening the door to smooth integration into water-based processing.

PHBV - SPF Booster

PHBV aqueous dispersion is a biobased and biodegradable alternative to conventional synthetic SPF boosters such as PMMA and Styrene/Acrylates Copolymer, which generate persistent microplastics upon disposal. Its micron-sized spherical particles scatter UV radiation, extending the optical path length through the sunscreen film and amplifying the effect of both mineral and organic UV filters, allowing the same SPF to be reached with less active filter. Fully biodegradable per OECD 301F and supplied as a stable aqueous dispersion, it integrates smoothly into existing formulations. As an SPF booster rather than a UV filter, it typically does not require Annex VI approval, offering a faster route to market.
