Modern, sustainable waste management is a given in the rapidly growing Barkarbystaden. With Järfälla waste collection terminal, Tengbom has designed a facility that integrates seamlessly into the urban fabric.

A new district means new waste, and planning for its management must start early. Instead of hiding the problem, Järfälla’s terminal uses an efficient underground vacuum system, transporting waste discreetly beneath the streets. But this is more than just a technical solution — it’s a building that earns its place in the ambitious Barkarbystaden.

Järfälla Municipality wanted a facility that matched the high standards of the surrounding architecture. As lead consultant, Tengbom ensured a thoughtful design, with quality materials and careful attention to detail.

Timeless details built to last

The result is a pared-down brick building, where faceted bricks form subtle patterns along the long façades. Some of the recesses remain open, while others are filled with mortar, creating either a smooth grid effect or striking diagonal patterns when snow settles in the cavities during winter.

The terminal was designed to blend naturally into its residential surroundings while still having its own distinct identity. Through careful detailing, it signals the importance of waste management in a modern city.

With room for future expansion, the terminal is built to serve the district for years to come. But longevity is about more than just capacity — it’s also about material choices and timeless design. Achieving an elegant, simple form requires a deep understanding of the underlying technology, making close collaboration with industry experts essential.

A shared vision for the city of tomorrow

There’s no manual for designing a facility like Järfälla waste collection terminal. Instead, it was a journey taken together with the client, ensuring a clear vision from the start — one that shaped the end result and kept costs in check.

With shared ambitions and a commitment to sustainability, something as unglamorous as a waste collection terminal has become a landmark for the neighbourhood. Winning Järfälla Municipality’s honorary award seems like proof of that.

Northvolt Ett

Battery-operated future on a massive scale

Client:
Location: Skellefteå
Description: Lithium-ion battery production factory
Assignment years: 2017-

The automotive industry is advancing rapidly. Northvolt chose Skellefteå for its lithium-ion battery production for electric cars and selected Tengbom to design the enormous facility. The team integrates societal benefits and thoughtful design as essential elements in building a more sustainable future.

Northvolt

Enormous in size

Northvolt has begun establishing its primary battery production plant on the outskirts of Skellefteå. The project is a major initiative to manufacture lithium batteries for cars and other industries, driving the next generation of energy. The test lab in Västerås is already operational, and large-scale production at Northvolt Ett is set to launch in 2021.

This massive project presents many architectural challenges. The team is working with groundbreaking technology and processes, but the prototypes are not yet built. The plant’s footprint exceeds that of Stockholm’s old town, and the timeline is tight.

Northvolt Ett

Positive impression

The architecture must unite the different spaces into a complete, well-functioning, and engaging whole without feeling monotonous or heavy. The factory may not be front and center, but its exterior still matters. It will leave a lasting mark on the natural landscape and must be designed with that in mind. The team will use wood for most of the exterior to blend with the surroundings. Metal, glass, and concrete will complement the structure. Recyclability and durability have guided the design process. Inside, the team also tackles challenges related to logistics, process flows, and creating a pleasant work environment.

Northvolt Ett

An assignment that benefits society

Northvolt Ett will employ around 3,000 people, creating many new jobs in the municipality. Tengbom took on the project because of its strong societal benefits—both socially and in the transition from fossil fuels. The client’s focus on visual experience also makes the collaboration rewarding. With the current rush to join the battery industry, flexibility and stress tolerance are key. Quick thinking and fast adjustments drive the project forward. After all, it takes both a positive and negative charge to generate the energy that powers progress.

Client: Karlstads Energi
Location: Karlstad
Years of commission: 2011-2015
Type of project: CHP Plant
Collaborative partners: WSP, JD-gruppen, KVE Konsult, Brandskyddslaget
Competences: Industry

When Karlstad Energi was ready to start construction on the third stage of Hedenverket, we were involved as architects throughout the entire process. This power plant is Karlstad municipality’s greatest investment ever and when it comes to projects this large, it is particularly important that we can contribute to an efficient process.

We did the volume study and developed the architectural idea at the feasibility study stage. We were also responsible for the model visualisation and the system documents; we participated in the procurement of the land, the construction hire and contractor processing, and in the work on the construction documents for the project.

Visualising the process

Part of our work with Hedenverket was to visualise the planned building process. We also developed the tender documents to the suppliers illustrating the supply limits in 3D models. The entire project was completed in a fully developed BIM planning in ArchiCAD, where the architecture model is added to the other player’s models for more coordinated planning.

A very successful project

Hedenverket is a project that we are incredibly proud of. Thanks to excellent planning and successful procurement, the cost for the investment came in at approximately SEK 150 million less than calculated. Despite this, Karlstad Energi got an even bigger boiler and a more powerful turbine than they had planned for.

More environmental gains

The new power station has played a key role in eliminating fossil oil from district heating production. In just 30 years, Karlstad’s district heating has transitioned from full oil dependence to being completely fossil-free. The station has also doubled renewable electricity production at Hedenverket, increasing output from 100 to 200 GWh. This amount covers the annual electricity consumption of 66,000 apartments.

Ursvik Waste Vacuum Terminal

An unexpected architectural gem

Client: Stora Ursviks KB
Location: Stora Ursvik, Sundbyberg
Years of commission: 2012-2014
Type of project: Industry building
Collaborative partners: SWECO, COWL, Tyréns
Competences: Infrastructure, Industry, Landscape, Sustainability

The new waste vacuum system terminal in Stora Ursvik is run completely by computers and is covered by a large wall of vegetation irrigated by sensors controlled from London. Welcome to a highly technological and environmentally friendly industrial building that – rather unexpectedly – has become a true architectural gem.

Is it possible to create a waste vacuum system to be proud of?

It was an exciting challenge we took on, to create the waste vacuum terminal in Stora Ursvik. We wanted the building to add aesthetic value to the area and become an appreciated part of the surroundings for the residents. It also had to be efficient both from a functional and environmental perspective.

Based on our vision, rational volumes emerged with few but clear effects produced. Industrial architecture with unexpected elements. The sloping façade of the largest volume covered in sheet metal contrasts with the adjacent volumes, that we covered in concrete and decorated in part with a shadowy forest motif. Offsets on the façade, a minimalist window distribution and a beautiful chimney in Corten steel plate gives a strong character to the building. It is exciting for a viewer to see both close up and at a distance.

The first BREEAM-certified industrial building in Sweden

A plant wall for cleaner air

The most effective contrast however, is probably the 250 m2 plant wall which covers the largest volume on one side. The wall consists of more than 2 000 plants and the irrigation is controlled from London using sensors. The green wall, meant to compensate for the land used also extends the life span of the building, filters pollution and cleans the air around it.

BREEAM-certified – and odour free

The waste vacuum terminal is the first BREEAM certified industrial building in Sweden. Fully functional, the system will serve approximately 6 000 flats. Through underground pipe systems several hundred meters long, food waste, packaging and paper is transported to the waste vacuum system from the homes surrounding it. The system is a closed one that keeps out both pests and insects. It does not smell either.

The building in Ursvik is normally unmanned and fully controlled by computers. The containers are emptied once a week. Heavy waste and recycling transporters use the nearby E18, keeping local traffic to a minimum. As a result, the streets become safer for both adults and children.
