Alco Energy Rotterdam is the largest biorefinery in Europe. The result of a unique collaboration between Alcogroup and Vanden Avenne Commodities. In the Port of Rotterdam we are producing since 2010 ethanol for fuel, animal feed, green CO2 and electricity. We play a pioneering role in reducing greenhouse gases. Our ambition is to be climate neutral by 2030. About us

Our biorefinery

Our factory is a biorefinery in the true sense of the word: biomass (grain) is converted into bio-ethanol, protein-rich animal feed and green CO2. And we do this in a very efficient way. It makes us one of the world leaders in our sector.

Our Products

The corn kernel is used in an optimal way. At AER, we currently manufacture 3 products from that grain: bio-ethanol, animal feed and CO2. The next step is to also make corn oil. But we don’t stop here. We are constantly looking for ways in which we can innovate both in the kind of raw material and our products.


The ecological footprint is directly linked to what concerns us on a daily basis. For 30 years, we continued to research, develop and apply new methods and knowledge in our sector. This pioneering spirit is part of our identity and will drive us for at least another 30 years.
