Finnish firm to install waste gasification system on cruise ship
The system will enable the safe disposal of waste onboard the ship through a self-fuelling thermal decomposition unit which is designed to reduce greenhouse gases. It will also help to lessen the requirement to offload waste at shore facilities. The order was placed by Carnival Corporation, the owner of Princess Cruises, in July 2019.
Wärtsilä’s gasification unit will replace one of the ship’s onboard incinerators and will safely dispose of hazardous, contaminated and dry-burnable waste in a sustainable way. The emissions quality from the system ‘exceeds the standard of land-based thermal destruction’, according to Wärtsilä.
The gasification system will also recover energy from the waste heat being produced by the thermal destruction process, meaning additional energy and emission savings can be gained. The system will help to reduce the vessel’s waste to less than 5% of the original volume and will produce BioChar, a sterilised material which is recycled within the unit as fuel.
Jason Hardy, head of sales, Advanced Waste Management (Retrofit) at Wärtsilä Marine, said: “Wärtsilä and Carnival have cooperated closely on numerous projects over the years, and we have delivered a number of advanced waste treatment systems for their vessels.
“Our experience with the auto gasification technology will help support them in their focus on efficiency and environmental sustainability.”
