2nd PHA platform World Congress 2021

…from Embryonic to Early Growth

PHA (Poly-Hydroxy-Alkanoates or polyhydroxy fatty acids) is a family of biobased polyesters. As in many mammals, including humans, that hold energy reserves in the form of body fat there are also bacteria that hold intracellular reserves of polyhydroxy alkanoates. Here the micro-organisms store a particularly high level of energy reserves (up to 80 % of their own body weight) for when their sources of nutrition become scarce. Examples of such Polyhydroxyalkanoates are PHB, PHV, PHBV, PHBH, and many more. That’s why we speak about the PHA platform.

This PHA-platform is made up of a large variety of bioplastics raw materials made from many different renewable resources. Depending on the type of PHA, they can be used for applications in films and rigid packaging, biomedical applications, automotive, consumer electronics, appliances, toys, glues, adhesives, paints, coatings, fibres for woven and non-woven and PHA products inks. So PHAs cover a broad range of properties and applications.

That’s why bioplastics MAGAZINE and Jan Ravenstijn now organized the 2nd PHA-platform World Congress on 22–23 September  2021 in Cologne / Germany. This congress continued the great success of the 1st PHA platform World Congress and the PHA-day at the Bioplastics Business Breakfast @ K 2019.

The congress addressed the progress, challenges and market opportunities for the formation of this new polymer platform in the world. Every step in the value chain was addressed. Raw materials, polymer manufacturing, compounding, polymer processing, applications, opportunities and end-of-life options were be discussed by parties active in each of these areas. Progress in underlying technology challenges was also addressed.

Disappointingly, the Coronavirus pandemic has forced us to revise our plans for the 2nd PHA platform World Congress, initially scheduled for September 2020. 

The event was held as a hybrid event. 

The event was recorded and it is still possible to buy the video-on-demand. The price is the same as the online participation. You can even still ask questions via e-mail. register for the video-on-demand. Just contact mt@bioplasticsmagazine.com


We use WHOVA for advanced networking opportunities across all attendees (on-site and online), as well as for organizer notifications, ZOOM interation for online attendees and much more...

Corona Pandemic Info

Hybrid event (on-site & online)

If the development of the pandemic (infection rates, vaccination, etc.) allows, the second PHA platform World Congress will be held as a hybrid event (on-site and digital) in the Maternushaus Cologne, Germany.

Travel to Germany

We sincerely hope that you may and can travel to Germany. We don't know about the restrictions your country may have on the day of travel.
For information on entry rules issued by the German Government, please visit
www.bundesgesundheitsministerium.de, providing info in 18 languages. We try to keep this info updated.

Travel home

If you need a negative PCR test for your flight home, you find useful info here:


The location is Hohenzollernring 32-34 (Cologne). That is about 1.3 km (less than a mile), so, a 15 min walk or a cheap taxi ride.

Hygiene Concept of the Hotel

The Maternushaus has elaborated a comprehensive hygiene concept.
Eine deutschsprachige Version ist hier verfügbar.

It includes that all conference attendees must be either fully vaccinated, recovered from COVID19, or negatively tested. Most probably a test can be performed on-site. But capacity might be very limited.

Cancellation Policy

Basically, our general cancellation policy applies.

However, due to the pandemic situation, we will handle it a bit more flexibly. If you register for the full on-site conference, we'll send you an invoice and ask you to pay this on time. In the case you have to decide to step back to an online-only participation at a later point in time, we can change your registration and we'll refund the price difference. Such a change, however, must be performed at a maximum of 48 hours.

We are all keen on holding an in-person event, as networking and socialising over a glass of good German beer is something that is so important and is high on the list of things that we all miss so desperately.
