Greywater and blackwater: closing the compliance gap

Marinfloc Service & Support managing director Ola Larsson said his guiding principle is rooted in purpose. “Marinfloc’s vision, A Clean Sea, continues to guide my leadership – not just as a statement of intent, but as a daily reminder of why we exist and what impact we aim to make.”

Mr Larsson is taking part in the Riviera webinar Greywater and blackwater: improving the compliance gap, which takes place on 30 October, 09:00 GMT. It will examine practical routes to more reliable wastewater management and enforcement-ready operations.

Mr Larsson’s route into the subject runs through engineering and operations.

“My professional journey began in 2002 at Ciserv. In 2006, I joined Marinfloc, and since 2009 I have served as managing director.”

He explained his emphasis has shifted over time from pure technology towards practical outcomes on board, where reliability, compliance and environmental value are tested every day.

“I believe true sustainability means creating solutions that are both effective for the planet and viable for business.”

For wastewater specifically, Mr Larsson pointed delegates to a clear technical message. “At present, our main focus is on increasing awareness of flocculation as the most efficient and reliable method for treating contaminated water on board.”

He added process control and evidence are becoming central to how crews operate and how management demonstrates due diligence.
