“Our new aggregates type allows water to soak through up to three times more efficiently than traditional aggregates. We’ve been developing this product for many years, and our challenge was to find the correct mixture of different rock sizes,” Anders Jensen, CEO of Roskilde Sten & Grus ApS, describes the development of the new aggregates type.
“New Danish legislation requires that aggregates developed for climate change needs must be used in the foundations and parking areas of the state’s construction projects. This means the ground effectively absorbs water so that it doesn’t flow into the sewage network and cause flooding,” Jensen continues.
More than 100,000 metric tons of aggregates to tackle climate change
Roskilde Sten & Grus refines this climate change aggregates and other required varieties from gravel and sand from the former seabed. Over an area of 200 hectares, the company uses 17 crushing, screening and washing plants to produce more than 50 end products – between 1.5 – 2 million metric tons a year.
There are aggregates types for everything: foundations, concrete and asphalt production, and building golf courses. Each year, the company produces approximately 100,000 metric tons of climate change aggregates, and demand for it is growing quickly.
