Sustainability at Boskalis goes beyond managing our business and projects in a responsible manner. We seek to leverage our ability to influence and innovate, to create added social, environmental and economic value where we can. These cases illustrate our approach in action.

Overview sustainability cases


Port XL: sustainable innovation

For the last five years, Boskalis has partnered with PortXL, a Dutch organization scouting and selecting innovative new companies that can serve the needs of the global maritime industry, bringing external innovation inside the company.


Griend nature preservation project

Boskalis teamed up with the Dutch Society for the Preservation of Nature (Natuurmonumenten) to protect the uninhabited island of Griend in the Dutch Wadden Sea. The island provides a vital habitat for hundreds of thousands of migratory and breeding birds. However, due to erosion this bird paradise was at risk of being washed away.


Contributing to the circular economy

In 2016 Boskalis and HVC, the largest non-commercial waste collection company in the Netherlands, opened the world’s first bottom ash washing plant. The plant recycles incinerator bottom ash, a by-product of the incineration of household waste in waste-to-energy plants.


Calling a halt to coastal erosion

Boskalis, as one of the partners in the EcoShape consortium, has embarked on a five-year Building with Nature project to halt coastal erosion in Central Java. Through a unique integration of mangrove restoration, small-scale engineering and sustainable land use the project is expected to turn the tide.


Marker Wadden

In March 2016, Boskalis started work on the first stage of one of the largest nature restoration projects in western Europe - Marker Wadden. The project will transform the ecologically impoverished Markermeer lake into a dynamic area rich in animal and plant life, through the creation of nature islands using sand, clay and fine sediment. Building with Nature techniques play a key role in the project.


3D printed reefs

Boskalis will create and install six artificial reef modules at the Larvotto reserve in Monaco in 2016, as part of a 3D reef pilot project with Prince Albert II of Monaco’s foundation and the Monaco Larvotto Reserve. The reefs, consisting of sand, will be constructed using a 3D printer. They will be used to improve the ecology and the quality of the seawater at the reserve.
