Boskalis Sustainability Report 2020

IJBURG In 2020 Boskalis created a 85-hectare artificial island,

The island was made by transferring sand through underwater and floating pipelines from the nearby Markermeer and building it up in some 15 layers; three breakwaters were also built. The projected date for completion is end 2021, and the island will accommodate around 6,200 new homes as well as an artificial beach and a recreational area.

Strandeiland IJburg, on the edge of Amsterdam. Biofuel was employed on one of the vessels used for the project, the Rhenus, allowing the project to achieve its goal of a 10% reduction in CO 2 emissions. In addition, both the Rhenus and the Zijpe were rebuilt, resulting in a reduction in nitrogen oxide emissions of 90%.

BRABANT, THE N69 In 2020 Boskalis won the tender for an EUR 80-million project to build ‘the greenest road in Brabant’, which will connect this southern Dutch province with Belgium. On completion, scheduled for end 2021, the N69 will have saved 20% of CO 2 emissions, against the design reference. Boskalis realized this reduction by, for example, using recycled materials in the asphalt, and replacing some of the concrete in the tunnels with a water-resistant foil that substantially reduces carbon emissions. But the client was also looking for innovative solutions; as part of this same project, Boskalis will build the first (cycle) bridge in

the Netherlands to be made from 100% geopolymer concrete, a material that relies on minimally processed natural materials and industrial byproducts to reduce the carbon footprint by almost 70% over traditional concrete. The material is also highly resistant to many common concrete durability issues. This demonstrates Boskalis as a frontrunner in its innovative approach to carbon-reductive infrastructure.
