One of the challenges the shipping industry has faced in using the technology known as deployed scrubbers to clean up emissions from ships’ chimneys is the waste generated by the process. The Port of Le Havre, in France, in partnership with SEREP, a subsidiary of SARP Industries, has announced its intention to develop a local industry for the treatment of scrubber residues.
Le Havre notes that the port is located within the SECA (Sulfur Emission Control Area) which was launched in 2015. The regulations of the area establish sulfur emission rate limits (SOx) which must not exceed 0 , 1%. Vessels operating in the SECA or moored in the port must either use fuels containing no more than 0.1 percent sulfur or be equipped with a closed-loop washing system to filter and wash the exhaust gases. .
To offer solutions to shipowners who use scrubbers, the Port of Le Havre and SEREP have worked on setting up a collection and treatment system for scrubber waste. Waste from ship exhaust gas purifiers is transported by truck to the treatment and recovery center for processing.
“Alongside the global maritime industry, the Port of Le Havre has embarked on an ambitious ecological transition to reduce the carbon footprint of its activities on the environment”, explains Baptiste Maurand, Managing Director of HAROPA – Port of Le Havre . “Among the actions carried out, there is the development of a wastewater treatment system. To promote it and make it sustainable, we have also set up a financial incentive for our customers, covering 30% of the cost of collecting liquid waste, including scrubber residues.
The port is joining forces with SEREP, a subsidiary of SARP Industries, which in 2011 developed a maritime waste collection activity to provide a local response to the needs of ships in the port. This port service, called SWC (Service Waste Collection), started with waste and water / hydrocarbon residues and is now extended to the management of scrubber residues.
“Since its creation, SEREP has always cultivated its spirit of innovation to provide efficient services to all industrial and maritime players in our region. In order to respond to environmental issues and to support the entry into force of new regulations, the company has expanded its range of solutions with the collection and treatment of scrubber residues. In synergy with partner companies including Sedibex, our teams ensure the continuous improvement and complementarity of our tools, to maintain quality and responsive service to our customers ”, explains Laurent Gallien, SEREP Director.
The partnership is also exploring additional efforts to turn the industrial port area of Le Havre into a smart industrial eco-park. SEREP is currently finalizing a proposal for a short-circuit recovery project for hydrocarbons collected on ships.
