CSR Report 2018

MANAGING OUR IMPACT ON THE ENVIRONMENT CSR 2018 – BOSKALIS 22 FRAMING THE CONCEPT 2011 We invited a selection of our most important suppliers to structurally expand the dialog on sustainability during a series of ‘Meet the Buyer’ sessions. One of the outcomes of these meetings was the idea for potential use of cleaner fuels. In addition to an excavator testing project, we became the first shipping company to use GTL (Gas-to-liquid) fuel in the propulsion system of a tugboat, the Smit Elbe, which operated in the port of Rotterdam. It enabled some NOx reduction and significant Particulate Matter reduction without hardware modification. Together with our suppliers, we further explored biofuels as a way of reducing emissions, without capital-intensive fleet renewal or retrofitting. We established a partnership with SkyNRG to create volume in the Bio(Jet)Fuel market – as part of which we were the first to use a 30% biofuel blend in our sand dumping trucks. From dialogue with suppliers in 2011, to offering proven solutions for our clients in 2018, our journey towards cleaner fuels has been successful, but there is still lots more to do to scale this solution. OUR JOURNEY TOWARDS CLEANER FUELS


We formalized a partnership with GoodFuels (successor SkyNRG for Marine market) and Wärtsilä to begin a two-year pilot program with the aim to accelerate the development of sustainable, scalable and affordable drop-in marine bio-fuels.

The lab testing program, which took place at the Wartsila premises in Finland, was completed.

We successfully tested drop-in biofuel (Hydrotreated Vegetable Oil (HVO)) on the Willem van Oranje trailing suction hopper dredger vessel. On the Marker Wadden project we performed dredging work for six months using a biofuel blend made out of lignocellulosic waste streams of up to 50% Our 2 years of testing and sea trials demonstrate that drop-in biofuels can lead to an impressive reduction in CO 2 emissions - of up to 90% compared to fossil fuels, and are also much more effective than alternatives such as liquefied natural gas (LNG) to reduce the CO 2 emissions.
