World’s first bridge built with carbon neutral concrete

Holcim-subsidiary Paebbl and Dutch builder Heijmans have installed a 7m-long pedestrian bridge in Rosmalen, the Netherlands, which the team describes as the world’s first bridge built with CO₂-neutral concrete, reported GCR.

About 30% of the project’s cement was replaced with Paebbl’s carbon-storing material in a concrete mix made 75% from what Paebbl calls “circular raw materials”.

The Health and Safety Advisor will provide the local advice and support necessary to assist managers and staff to fulfil their safety responsibilities to the high standards demanded by the business.

Biochar in the mix means the bridge deck has permanently sequestered 66kg of CO₂, stated the report.

Speaking to GCR, Paebbl’s vice-president of products, Ana Luisa Vaz, said it would be difficult to replace more than 30% of traditional cement while meeting structural requirements.

But she noted that the base cement used is one of the lowest-carbon cements commercially available.

The bridge “demonstrates that carbon-storing materials aren’t just viable for decorative or non-structural uses, they’re ready for real infrastructure,” she added.
