co2 compensatie snelheid en hoeveelheid

Project data

Location: South Holland
Cleanup potential: 16,000 tons of CO₂

Along the track Rotterdam-The Hague

Carbon Cleaning inspection path

To reduce the CO₂ emissions of the Hoekse Lijn, it was decided to use greenSand as CO₂ remover. The semi -hardening of olivine-rich rock was applied to the two 15-mile (24 km) stretches along the track. The Hoekse Lijn was the first railway line in the Netherlands where this product was successfully used.

Characteristics of greenSand inspection path material

• Captures CO₂ in a weathering process
• Low maintenance due to deacidifying effect
• 100% natural
• Complies with ProRail SPC000173-3.
Gradation 0-6 mm

Interview with RET Pieter van der Tang

"Hoekse lijn" gobbles up CO₂


RET, provider of public transport in the Rotterdam - The Hague region, argued in 2016 for the use of olivine stones in public transport. They found a good partner in contractor ETS Spoor, who installed a total of 16,000 tons of greenSand Olivine on the inspection path.


A 13 cm thick layer of greenSand inspection path material has been applied to two strips along the track over a length of 24 km. This is compacted to 10 cm. This results in a stable surface for the inspection path , which, over time, removes around 16,000 tons of CO₂ from the air and permanently removes it.

Less weeds

An additional advantage for RET is that the olivine-rich rock transmits heat well, making it more difficult for seeds to germinate. With the greenSand inspection path material, a sustainable material has been found that cleans up CO₂ and also prevents the growth of weeds.

Cleaning up CO₂ from the train

One of the most important civil applications of greenSand is the use of olivine-rich rocks along the track.

It would be great for travelers to have CO₂ permanently cleaned up while they are on the train and comfortably taken to their destination. greenSand offers a solution to mitigate the effects of climate change.

To continue and improve the economic system, it is necessary to limit the impact of infrastructure and public transport systems due to the enormous risk of CO₂ emissions. Think how easy it is to remove CO₂ by replacing porphyry or other materials with the CO₂ removing greenSand Olivine?
