Stockholm Royal Seaport
Stockholm Royal Seaport, in Swedish known as Norra Djurgårdsstaden (NDS from now on), is one of the largest urban development projects in Europe.
Spanning 236 hectares and ranging from Hjorthagen in the north, moving across the port area and down to Loudden in the south, the former industrial zone is groundbreaking not just for its sustainability targets, but also for its collaborative approach that has seen Stockholm’s city administrators, businesses, and developers work together to achieve common environmental goals.
Following its success with Hammarby Sjöstad – Sweden’s blueprint for sustainable development – Envac was selected to become NDS’s waste collection technology partner in order to share the skills, knowledge and expertise gained through being a part of one of Stockholm’s most high-profile developments to date.
By 2030, NDS is expected to include at least 12,000 new housing units and 35,000 workplaces – all of which will be connected to Envac’s automated waste collection system, one of the many innovative environmental technologies embedded within the development’s fabric.
With ambitious targets focussed on effective resource management and delivering an overall structure that supports multiple ecosystems, NDS required the highest standards from its partners and a waste collection solution that provided usability, functionality and sustainability in equal measure.
With both waste inlets and approximately 100 self-emptying litterbins scheduled for installation in the public areas of the northern part of NDS, Hjorthagen, which covers 6,000 residential units, Envac has ensured that waste can always be deposited and quickly transported to the site’s waste collection station without any need for waste collection lorries to come into contact with the waste or the inlets.
Furthermore, with over 400 additional waste collection inlets designated for residential and commercial buildings scheduled for installation in Hjorthagen by 2027, Envac has provided a long-term sustainable waste collection solution for all those who live and work in NDS. As of 2018, 50 per cent of the inlets are installed and currently serve the development.
In addition to providing ready access to an automated waste collection system, Envac has worked closely with NDS in order to create behaviour change and help establish positive recycling habits.
For example, over 8,000 RFID tags have been registered to households throughout Hjorthagen so that the city can identify user waste habits, including the type of waste deposited and the inlets used, of those living in the area.
This is possible thanks to the Envac Automation Platform (EAP), based on the latest Smart solutions as built in database, report generator, adaptive emptying scheduler as well as prepared for connection to both IoT terminals and management systems. In addition, EAP is prepared for add-on functionality as AI niklcontrol.
Remote system access is done through Envac System Platform, a recently developed cloud platform allowing for remote monitoring and control of both the latest and earlier delivered systems.
The latest EAP system provide graphic real-time status of both inlet area and the central station equipment.
The inclusion of a heat exchanger in the waste collection station, which enables heat generated from the system to be directed back into the building, has also ensured that it’s not just the site’s waste that is handled sustainably.
Envac’s inclusion in the NDS project has:
As a former Envac employee I was always aware of the value that the system can add to any development and the countless sustainability benefits it creates. However, having the opportunity to see how Envac fits into the wider picture, as I do now in my new role, I am able to see first hand the positive impact Envac has on communities when it works alongside other sustainability-focussed technologies. NDS is an extremely impressive project and one that is likely to set the international standard for many years to come.Magnus Ekholm, former Envac employee and consultant on the NDS project
