What to Expect at the 4th PHA World Congress

The conversation around sustainable materials has never been more urgent—and one biopolymer family is rapidly capturing global attention: Polyhydroxyalkanoates (PHAs). These bio-based and biodegradable plastics hold immense promise for applications ranging from packaging and consumer goods to healthcare, textiles, automotive components, and beyond.

This September, the spotlight will once again shine on PHAs at the 4th PHA World Congress, taking place September 2–4, 2025, in Düsseldorf, Germany, with a hybrid format for both in-person and virtual participation. Organized by Renewable Carbon Plastics Magazine in collaboration with GO!PHA, the event has become the definitive meeting place for anyone passionate about advancing PHA technology, scaling its production, and unlocking its market potential.

A Global Forum for PHA Innovation

The PHA World Congress stands out because it is the only international conference dedicated entirely to PHAs. Over the course of three days, it brings together producers, brand owners, technology developers, researchers, policymakers, and investors from around the world. It’s a unique opportunity to explore every stage of the PHA value chain—from feedstock selection and fermentation processes to product performance and end-of-life solutions.

The goal? To accelerate innovation, foster collaboration, and push PHAs further into mainstream markets as a critical solution for reducing plastic waste and dependence on fossil resources.

Day-by-Day Highlights

September 2 – Pre-Congress Immersion

The Congress opens with an optional PHA Masterclass, led by GO!PHA experts. This intensive, 2.5–3-hour session is designed for newcomers and seasoned professionals alike, offering a structured overview of the science, applications, and economics of PHAs.

For those seeking to connect before the main event, the Matchmaking & Investor Pitch Session offers quickfire opportunities to present ideas, seek collaborators, or secure investment. This format is particularly valuable for start-ups, innovators, and research teams looking to gain visibility and traction.

September 3–4 – Main Congress Experience

The heart of the event unfolds over two days packed with keynotes, panel discussions, and technical sessions covering the entire spectrum of PHA development:

  • Material and Processing Innovations – From advances in fermentation processes to improved compounding and product design.

  • Market and Application Development – How brands and manufacturers are integrating PHAs into their product lines.

  • Policy, Regulation, and Standards – Ensuring PHAs meet both environmental and market requirements.

  • End-of-Life and Circularity – Composting, biodegradation, and recycling strategies for closing the loop.

In addition to technical content, Strategic Industry Dialogues will gather senior leaders to tackle pressing challenges such as scaling production capacity, financing new plants, and building market awareness. These sessions are free to all registered attendees.

Networking that Lasts Beyond the Event

Connections made at the PHA World Congress don’t end when the lights go down. The event uses the WHOVA networking platform, which remains active for six months after the conference. Attendees can exchange contacts, arrange follow-up meetings, and continue discussions started on-site or online.

Even better, nearly all presentations will be recorded and made available for on-demand viewing—ideal for catching up on missed sessions or revisiting key insights.

A Hybrid Format for a Global Audience

Whether you attend in Düsseldorf at the Maritim Airport Hotel or join virtually from anywhere in the world, you’ll have access to the same core program.

On-site tickets are priced at €1,350, while online attendance costs €1,250
