A4F ALGA FUEL SA

Their core work

A4F Alga Fuel is a Portuguese SME specializing in microalgae cultivation and biorefinery — growing algae at industrial scale and extracting high-value compounds like proteins, lipids, omega-3 fatty acids, pigments, and carotenoids. They work across the full algae value chain, from strain selection and biomass production to downstream processing of bio-based products for food, feed, and fragrance industries. Their applied expertise also extends to using microalgae for carbon capture and valorisation of industrial waste streams, particularly from the wine sector.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), A4F focused on foundational algae science — algal aquaculture, microbiome research, and biofuel applications — contributing as a partner in research-oriented consortia. From 2020 onward, they shifted decisively toward applied biorefinery and circular economy, culminating in their role as coordinator of MULTI-STR3AM, a large-scale multi-product microalgae biorefinery project. The trajectory is clear: from algae biology and energy research toward commercial-scale extraction of high-value bio-based products for food and feed markets.

A4F is moving from research participant to industrial biorefinery leader, positioning itself as a go-to partner for anyone needing algae-derived ingredients at commercial scale.

How they like to work

A4F has primarily operated as a participant (4 of 5 projects) but took the coordinator role in their largest and most recent major project, MULTI-STR3AM, signalling growing maturity and ambition. With 67 unique consortium partners across 15 countries, they maintain a broad European network rather than relying on a small circle of repeat collaborators. This makes them a well-connected, experienced partner who can both contribute specialist algae expertise and — increasingly — lead project work packages or full consortia.

A4F has collaborated with 67 unique partners across 15 countries, giving them a well-distributed European network. Their connections span academic institutions (via ALFF and MSCA training networks) and industrial players in food, energy, and bio-based sectors.

What sets them apart

A4F occupies a rare niche as an SME that bridges algae science and industrial-scale biorefinery — most algae companies are either pure research spinoffs or large commodity producers. Their demonstrated ability to coordinate a EUR 2M+ multi-product biorefinery project (MULTI-STR3AM) while remaining an agile SME makes them an attractive partner for consortia needing hands-on algae process expertise without the overhead of a large corporate partner. Their circular economy angle — turning wine industry waste into algae feedstock — gives them a compelling story for sustainability-focused calls.

Highlights from their portfolio

• MULTI-STR3AM
  Their only coordinator role and largest project (EUR 2.1M) — a multi-strain, multi-product microalgae biorefinery integrating industrial side streams, representing their strategic direction.
• REDWine
  Innovative circular economy concept using CO2 and liquid waste from wineries to grow microalgae — connects Portugal's wine industry with biotechnology in a distinctive way.
• ALFF
  Early-stage participation in fundamental algal microbiome research via MSCA training network, showing their roots in algae science before pivoting to industrial applications.
