European FOG Summit


The future of FOG

Our first ever European FOG summit has come and gone, I wanted to take a second to look back and reflect on some of the insights and shared ideas from the day. We were extremely fortunate to be able to bring together some of the leading experts in FOG from across North America and Europe. They all graced the stage and shared their experiences with FOG to shed new light on some of the major challenges which cities across Europe are dealing with.

Why we hosted the FOG Summit?

The goal was to bring together FOG innovators and European wastewater professional for an immersive day of learning and collaboration centered on innovative ways to tackle fatbergs through better FOG management.

As sewer networks come under increasing pressure from growing populations and the number of food service establishments continues to grow, new ways of managing FOG must be developed to safeguard the long-term sustainability of our urban communities.

We specifically looked to recruit speakers from around the world to give a truly global view of FOG. We’re all about sharing the wins, losses, and missteps along the way to give so that wastewater professionals and the public can learn how to manage fog sustainable in the long term.

Our speakers covered the entire wastewater lifecycle

We need to celebrate our successes a little bit more because the wastewater professionals are doing great things, we just don’t know what everybody’s doing. An event like the European FOG Summit gives us an opportunity to see what our colleagues are doing. We need to celebrate successes because I know they’re happening.” Barry Orr, Inspector at City of London

FOG 2.0

We wanted to emphasize “innovation through collaboration” not only in the fact that we hosting the first European FOG summit but also with the venue itself. Just last year we partnered with Waternet to launch our Vetstrijder (fat fighter) campaign in Amsterdam where we reached out to food service entrepreneurs and looked to raise awareness about the growing fatberg threat in the city.

We believe that outreach and continuous education is the key to changing how people think about and deal with FOG.

Our speakers

When selecting potential speakers to approach we wanted to make sure that we provided a holistic view of the FOG ecosystem throughout the day. That meant approaching speakers who operate throughout the FOG lifecycle including FOG managers, industry consultants, public water and the sewage industry, the hospitality and academia among others. We also wanted to make sure that we were featuring people who were looking to push the boundaries with the FOG efforts in new and interesting ways.

Another important factor that affected our choice was geography. We wanted to give a truly global view of the FOG scene and worked to recruit speakers from different areas who would be able to provide a unique view of FOG management in their city/region.

As head of office I am committed to innovative and effective supervision. Among others in the Horeca. Protecting the sewer is one of the focal points for the DCMR. Clogged sewers create environmental damage and inconvenience for both citizens and businesses. We want to prevent that. We work with a combined intervention approach: information and education, conducting inspections and (where necessary) deploying sanctions. For us it is essential to work together with municipalities and branch organizations to reach (start-up) catering entrepreneurs.

Cassandra administers the Tempe Grease Cooperative, an innovative partnership between the City of Tempe and its local food service establishments to manage FOG. It is the first program in the world in which a city uses its procurement process to establish and administer collective contracts which broker service quality and pricing for grease interceptor maintenance. Community restaurants voluntarily enroll for an easy way to comply with City Code. Furthermore, Cassandra and the Tempe Grease Cooperative are foundational in the state-wide effort to use FOG in codigestion for energy production.

After studying Law among onther studies at the University of Amsterdam, during which I always worked in bars, restaurants, dishwash kitchens etcetera, six years ago I became one of the the two proud entrepreneurs behind Eetcafe de Magere Brug and a few years later we added The Coffee and Bread Bar and Het Groene Paleis to our portfolio. The Café, the take-out and the restaurant are all located in the centre of Amsterdam. At Het Groene Paleis, located on the Rokin, situated under the offices of the NRC Handelsblad, one of the biggest newspapers in the Netherlands. There, we have one of the biggest grease traps of the city. We find that no more than common sense. Even our little café has a grease trap. Because, as citizens and entrepreneurs we realize that if we pollute our sewer system, not only entrepreneurs like us, but also every citizen in our country will have to pay to restore the system, and damage to the environment. The government, entrepreneurs, citizens are in this together in my opinion, because we’ll all pay, not today, but in the near future, for any lack of prevention of pollution to our sewer system and the environment

Michael has unparalleled experience in FOG compliance and regulation. Over a decade ago he worked at Dublin City Council, where he was tasked with launching Europe’s first Fat, Oil and Grease management program. Dissatisfied with existing management solutions, Michael developed an entirely new platform to eliminate fatbergs. Originally from Ireland, Michael now lives in Pleasanton, California with his family.

About us


The European FOG Summit is an initiative from SwiftComply, in cooperation with Stichting Waternet and co-funded by the European Union (H2020)

The SwiftComply story begins in Dublin in 2016, though our roots stretch back to 2008. At this time, our CEO Michael O’Dwyer was working as an engineer at Dublin City Council where he developed Europe’s first Fat, Oil and Gas regulatory program. The program was the first of its kind in Dublin and was designed to solve Dublin’s growing problems with excessive build-up of FOG.

Michael witnessed first-hand how the outdated regulatory processes and fragmented relationships between restaurant owners and regulators hindered virtually all clean up efforts.

After establishing the most effective FOG program in Europe and achieving a staggering 95% fatberg reduction in Dublin, Michael set about creating a tool that would revolutionalize how cities around the globe collaborate with the foodservice industry to solve this problem.

Joining forces between government and private stakeholders should prevent underground fat from becoming the next plastic soup.
