How the Mass Consolidation Centre works

In 2018, the Mass Consolidation Centre (MCC) was opened in Frihamnen to streamline bulk materials management with the help of on-site sorting and remediation. The facility is financed with grants from the City of Stockholm’s climate investment funds.

More than two million tonnes of excavated materials have been handled on site, of which one million tonnes at the Mass Consolidation Centre. In 2021, the MCC has processed 59,900 tonnes of excavated materials used to construct streets and neighbourhoods in Stockholm Royal Seaport. 36 per cent of this material was reused immediately, and materials that could not be used or were contaminated went to the landfill.

The Mass Consolidation Centre contributes to the increased re-use of excavated materials, thereby reducing the number of journeys to and from Stockholm Royal Seaport. The Mass Consolidation Centre is a key aspect of our work on efficient and sustainable transport.

Nearby residents have complained about noise and dust. As a result, noise measurements have been carried out and sound dampening measures at the centre have been improved.

Quieter crushing

The “quieter crushing” research project, with the aim of reducing noise levels at crushing and material handling sites, has been running for the past two years. By soundproofing and enclosing crushing sites, it is possible to reduce noise levels and dust. The project is funded by a SEK 2.7 million grant from Vinnova.

Treating and reusing rock crushed locally considerably reduces traffic on the city’s road network.
