Op 29 juni nam de Johan Cruijff ArenA een superbatterij in gebruik, gemaakt van accu’s van elektrische auto’s. De batterij van 3 megawatt dient als reserve-opslag van de energie die wordt gewonnen uit 7200 vierkante meter zonnepanelen. De batterij is slechts één voorbeeld van hoe het stadion dient als living lab voor innovatieve en duurzame oplossingen. Directeur Henk Markerink vertelt over de verschillende thema’s waar de Johan Cruijff ArenA de komende jaren op inzet.

Demoday #28: Designing for Circularity in the Port of Amsterdam

During Demoday #28, we focused on one of the key challenges in the circular transition: how can we make the Port of Amsterdam fully circular?
The Amsterdam port is one of the largest in Europe. It functions as a major energy hub, where fossil fuels still play a central role, and as an industrial hub, where massive flows of raw materials pass through. The City of Amsterdam has set the ambitious goal of becoming fully circular by 2050. This means the port must transform as well. This is a complex and far-reaching task that requires collaboration and innovation.
In this work session, we zoomed in on circular design: how can we make products and processes circular from start to finish?
A closer look at the port
James Hallworth, Commercial Manager at Port of Amsterdam, opened the session by taking the group on a tour through the world of the port. Located in the western harbour area, the port has two main responsibilities. First, it ensures the smooth and safe handling of all maritime traffic on behalf of the City of Amsterdam. Second, it manages and develops the land and industrial areas around the harbour.
To tackle circularity, Port of Amsterdam applies industrial ecosystem thinking. In nature, waste does not exist, and the same principle should apply here. The port aims to build collaborative networks between companies, where waste flows from one company becomes raw materials for another. There is already significant activity around recycling and recovery, but more can be done in higher-value strategies on the R-ladder, such as repurposing, remanufacturing, and refurbishment. Circular by design is a key concept in this shift.
The port is transitioning from measuring success in tons to measuring added value. This shift also means thinking differently about space: circular systems require space to receive, process, and recover valuable materials from waste streams.
Getting hands-on with circular design
Creating a fully circular production process is easier said than done. That’s why we worked through two real-world cases: construction materials and e-bikes. Participants split into groups and explored what a truly circular production process might look like. We also explored the potential role the port could play as an enabler of circular supply chains.
Some key takeaways from the session:
• Material passports: A digital document containing material properties and origin can greatly simplify recycling and reuse.
• Monomaterials: Products made from a single type of material are much easier to separate and recycle at the end of life.
• Smart synergies: Mapping which companies can use each other’s waste flows as input can unlock huge circular potential.
• Financial incentives: Right now, circular processes are often more expensive than linear ones. Smart financial mechanisms could help bridge that gap.
• E-bike challenges: In the case of e-bikes, batteries were flagged as a challenge. Recycling them is still very difficult, and since they are mostly produced outside of Europe, it’s hard to have control over the production process.
This session invited participants to take a step back and view products through a circular lens. The port has the potential to become a key player in the circular transition, but to get there, it will need ideas, insights, and input from across the network.

Welke taken kun je automatiseren zonder je hele proces om te gooien?
Hoe weet je of cobots geschikt zijn voor jouw productieomgeving?
En wat kost het – in tijd, geld én kennis – om echt aan de slag te gaan?
Op woensdag 23 april organiseren we een Innovation Dinner over robotica, samen met BouwLab R&Do – speciaal voor professionals in de maak- en bouwsector die serieus werk willen maken van slimme productie.
Franc Mouwen (European Innovation Council) deelt zijn inzichten over technologische doorbraken en de stappen die bedrijven écht verder helpen – van technische kennis opbouwen tot financiering en samenwerking.
Na het dinner kun je kiezen voor een tweedelige workshopreeks waarin we samen de praktijk induiken: wat werkt, waar begin je en hoe zorg je dat het blijft werken?
📅 Workshops: 7 & 14 mei | 13.00-17.00 uur

BouwLab Software Summit

Op 22 mei 2025 organiseert Smart Tech fieldlab BouwLab R&Do de BouwLab Software Summit 2025 in Haarlem. Het thema van dit jaar is "Beyond BIM", waarbij de focus ligt op de volgende fase in de digitalisering van de bouwsector. Het evenement brengt experts, softwareontwikkelaars, opdrachtgevers, ontwerpers en beleidsmakers samen om de digitale toekomst van de bouw vorm te geven.
Het programma bevat diverse sessies, waaronder:
✅ Studio Talks over AI, standaardisering versus parametrisering, datamodellen en ketensamenwerking.
✅ Software Stand-up Sessions met innovatieve softwareontwikkelingen.
✅ BouwBoosts en table-top presentaties om inzichten te delen en samenwerkingen te stimuleren.
✅ Netwerkborrel om in contact te komen met professionals uit de sector.
Tickets
🎟 Softwaregebruikers: €99 (excl. btw)
🎟 Softwareaanbieders: €499 (excl. btw)
Tickets zijn inclusief lunch, toegang tot alle sessies, de netwerkborrel en gratis parkeren.
