How we build circularly

Using resources efficiently is an important part of our sustainability efforts. The most resource-efficient material is often the material that already exists. That is why Fabege works with reuse, circular construction and conscious material choices in our building and refurbishment projects in the Stockholm region.

Here you can read about our reuse strategy, our circularity index target for refurbishment projects, and how we work with material selection, water consumption and waste management.

Circular construction and reuse

The climate impact of producing construction materials is significant. To reduce the climate impact of our building and refurbishment projects, we work to preserve existing resources and increase the reuse of building materials, plants and interior furnishings.
One of our sustainability targets is to halve emissions per square metre built (Scope 3 per GFA) by 2030. To achieve this target, we work systematically with circular construction and reuse.

As part of this work, we have:

  • developed a reuse strategy,
  • established the Reuse Hub (Återbrukshubben) in Solna Business Park as part of our circular construction initiative,
  • transferred the Reuse Hub to Ragn-Sells in April 2026 to enable larger volumes and more efficient material flows,
  • joined Ragn-Sells’ Reboost initiative in connection with the transfer of the Reuse Hub, enabling large-scale reuse of construction materials through shared logistics and quality assurance. Read more >
  • opened Stockholm’s first Reuse Park (Återbruksparken) in Arenastaden for the reuse of trees, shrubs and outdoor materials,
  • introduced a reuse target requiring all refurbishment projects to achieve a circularity index of at least 20 percent for installed materials.

Our reuse ladder

The reuse strategy describes our reuse targets as well as the routines and working methods needed to achieve them. The Reuse Ladder is a guide designed to challenge established ways of thinking and working:

  • Demolish as little as possible. Preserve existing structures and layouts.

  • Reuse materials already available within the premises.

  • Use reclaimed materials from other Fabege projects or from Reboost.

  • Source reclaimed materials from other marketplaces if suitable materials cannot be found within Fabege’s portfolio or through Reboost.

  • Choose materials with a high proportion of recycled content if new materials are required.

Always design and install materials so that they can easily be reused or recycled in the future.

Circularity index

To monitor our reuse efforts, we use a circularity index for installed materials in our refurbishment projects.

Our target is for all refurbishment projects to achieve at least 20 percent materials that are reused, recycled or based on renewable raw materials.

The index is used as a tool to increase the share of reused materials and products in projects and to track progress over time.

Circularity assessments guide how materials are managed

Before dismantling and refurbishment, we assess how materials can be retained and reused instead of becoming waste. Through circularity assessments, we identify opportunities for reuse and material recycling, while also determining what is required for dismantling, sorting and transport.

At Dalvägen in Arenastaden, the assessment covered approximately 45,000 sqm. In dialogue with contractors, material suppliers and potential recipients, we explored which building materials could be reused and which could serve as raw materials for new products. This approach was then incorporated into the procurement process through circular options and ongoing follow-up.

The target was for at least 80 per cent of the materials to be reused or undergo high-value material recycling. The final result was 97.2 per cent.

Reuse on a large scale requires new working methods, collaborations and consensus with our customers.

Reuse in practice

Increasing reuse requires both new ways of working and new forms of collaboration. Through reuse inventories, early-stage planning and cooperation with other stakeholders, we work to preserve materials and products that might otherwise become waste.

The Reuse hub and Reboost
In 2023, we established the Reuse hub in Solna Business Park to enable reuse on a larger scale. To create even better conditions for reuse, we transferred the operation to Ragn-Sells in April 2026. At the same time, we joined Reboost, an initiative that enables large-scale reuse of construction materials through shared logistics, quality assurance and more efficient material flows.

The Reuse park
In Arenastaden, we have established Stockholm’s first reuse park. Trees, shrubs and outdoor materials are temporarily stored here before being relocated to new projects and locations. The Reuse park is a key part of our work to promote the reuse of resources in urban environments.

Conscious material choices

Our ambition is to reduce the environmental impact of the materials we use. In all projects, we apply the assessments of Byggvarubedömningen and maintain a materials logbook to ensure that materials meet the required standards. Our objective is for 100 percent of our construction materials to comply with the requirements of Byggvarubedömningen.

To reduce resource use and climate impact in our projects, we work with material selection from the earliest stages. An important part of this work is reusing materials whenever it is technically, economically and qualitatively feasible.

We have signed up to Fossil Free Sweden’s roadmap for the construction and civil engineering sector and are also members of Klimatarena Stockholm. In addition, we participate in the Center for Circular Building (CCBuild), where industry stakeholders collaborate on reuse and circular material flows in construction, deconstruction and property management.

Our water consumption target

Lower water consumption contributes to more resource-efficient use of water and helps prepare our operations for future challenges related to the availability of freshwater resources.

In 2021, we began developing a quantified target to strengthen the monitoring of water use. Our target is to reduce water consumption by two percent annually.

Waste management

Waste arises from construction projects, tenant adaptations and the day-to-day operation of our properties.

Waste volumes are monitored using data from our main waste management contractors and are measured by volume, type and weight. Our customers are free to choose a waste contractor other than the one we recommend, which means that a small proportion of waste volumes is not included in our monitoring.

We promote responsible resource management and encourage our customers to sort their waste into at least five fractions. In all projects, we set requirements for waste management and material recycling rates. For BREEAM-certified properties, additional requirements for recycling and waste management apply.
