About Us

At the service of the waste-based and advanced biodiesel supply chain

Founded in 2013, the European Waste-based & Advanced Biofuels Association (EWABA) is a members-driven non-profit association focusing on supporting its members with a unique blend of information, services and interest representation.

EWABA provides in-depth policy, regulatory, and market information to its members and offers updates on legislative developments, strategy and the association's activities in Brussels and the EU via regular communications. To achieve our objectives, we have set up EWABA working groups that meet regularly on topics such as Government Affairs, Communications, Technical and Maritime affairs, to ensure the best possible intel and analysis for our membership.

EWABA represents its members before EU and national authorities aiming to achieve the best possible regularory framework for waste-based and advanced biodiesel. We also engage with media, research institutes and the wider public to better serve our members. Collectively we secure public policies that enable large-scale deployment of sustainable biofuels across the EU in the most efficient way possible. 

Our members are working together to produce sustainable renewable fuels of the highest quality creating added economic and environmental value. We are proud to promote the excellent work of our members in the waste-based and advanced biodiesel supply chain, and support them in their delivery of decarbonisation solutions for the EU transport industry. Together, we showcase the positive climate mitigation and socio-economic effects of our industry.
