TECHNOLOGY OVERVIEW

Polyhydroxyalkanoates (PHA) have become very popular as they are bio-based, bio-degradable natural polymers which are UV-stable, able to withstand higher temperatures, showing good resistance to moisture and providing a good barrier for aroma compounds, making them an ideal packaging material. In addition, they can also be used for high value applications such as biodegradable solutions for slow-release fertilizers, pharmaceuticals in general, as well as degradable human implants.

Conventionally, PHAs are produced using mainly (food/feedstock) sugars or oils as substrates. In contrast, this offer presents two independent methods using the greenhouse gas CO2 for the production of biopolymers. This allows for the environmentally friendly production of bio-based and biodegradable natural polymers in the sense of a circular economy.

TECHNOLOGY FEATURES & SPECIFICATIONS

The technology developed has the following features:

  • A technology based on the use of highly sophisticated strain of cyanobacteria to productively grow in a photobioreactor without sugars or oil using light and CO2, and to generate PHA
  • A technology using the bacterium Ralstonia eutropha (aka Cupriavidus necator), which is able to use H2 (e.g. from electrolysis of water using excess of electric energy) and CO2 to produce PHA has also been developed

High quality PHA produced by valorisation of the greenhouse gas CO2 is already possible with these technologies. Further optimizations and development are needed to beat current production costs.

POTENTIAL APPLICATIONS

Potential applications include but not limited to:

  • Production of bio-based, biodegradable natural polymers without the use of sugar or oil feedstock.

Market Trends & Opportunities

Currently more than 30,000 metric tons of PHA-biopolymers are produced annually with traditional technology using mainly (food/feedstock) sugars or oils as substrates. There is an increased demand expected in the future and an opportunity for non-food/feed CO2-based production systems.

Benefits

The client seeks investors and industrial partners to develop this technology to commercial scale. Under protection of a CDA/NDA, details on both CO2 recycling and the sustainable production of biopolymers opportunities will be provided.

Any IP developed in a joint project would fully belong to the investor/industrial partner.
