Due to the new demand from cruise yards for integrated waste treatment systems, Wärtsilä Water & Waste has developed a complete waste treatment package for ships where all systems are working together.
In practice, the new system of waste handling means better possibilities to reuse and recycle. Materials like metal and glass can now be collected separately inside the ship. Taken onshore when the ship comes to harbour, these materials can be transferred for recycling, and nothing goes to waste. The water is processed through a ‘grey and black water’ treatment system. The dried waste is handled together with bio-material and other burnable waste. It can be burned on-board in incinerators, which are also part of Wärtsilä’s waste-management system.
One of the benefits of a complete waste management solution is the footprint. On cruise ships, a surprisingly large amount of waste can build up in a short time. Before, the storing of the waste took a lot of space. But now, as the waste is largely managed on-board, there is less need to store it, therefore requiring less space on the ship. There are environmental benefits as well. The less energy the waste-management systems use, the less energy that needs to be produced. With total waste management the efficient process of collection, recycling and disposal in modern low-emission incinerators provides high efficiency, with the lowest impact on the environment.
