The brief

Converting an old industrial area and harbour into a modern city district was never going to be an easy task – particularly when plans for the conversion involved Hammarby Sjöstad becoming a flagship environmental project that would incorporate and showcase the very latest in sustainable technologies.

After an environmental programme was drawn up for Hammarby, which included rigorous sustainability targets and specified the most innovative environmental solutions as part of what would later become known as the ‘Hammarby Model’, Envac was appointed to demonstrate the value that automated waste collection (AWCS) could add to a contemporary urban environment.

From the outset, the City of Stockholm wanted to reduce the on-site presence of waste collection vehicles by 50 per cent – a target that Envac would be instrumental in achieving.

The project

The development, which began in 2004 and continues to evolve, now welcomes over ten thousand architects, local authorities, developers and planners from around the world each year, all of whom visit Hammarby to draw inspiration from the city’s ability to fuse function and style with practicality and sustainability. From biofuel and biogas to district heating and rainwater management, Hammarby illustrates what can be achieved through the successful integration of technology and the cooperation of local government and technology providers.

Five Envac systems currently serve the Hammarby community: three stationary systems that serve Norra Hammarbyhamnen, Hammarby Gård and Henriksdal/Lugnet and two mobile systems serving Sickla and Fredriksdal.

The systems have been collecting waste at certain locations and across three fractions including general waste, food waste and paper and street litter since the first system became operational in 2000. However, it is the scale at which Envac will operate on completion – and its ability to complement and integrate with other sustainable technologies – that has captured the imagination of a global population.

The result

As a result of Envac’s inclusion Hammarby has:

  • Set the global standard for sustainable waste collection in urban environments
  • Created a flagship model for sustainable development that continues to attract worldwide attention
  • Beaten its waste collection vehicle reduction target – Hammarby’s Envac system has since reduced on site collection vehicles by 60 per cent
  • Reduced waste sent to landfill by 60 per cent
  • Demonstrated how effective collaboration between local authorities, cleansing departments, water companies and energy companies can deliver effective eco towns
  • Installed a system that takes minutes to collect 20 tonnes of waste, each day and by airflow alone, from only 670 waste inlets and seven self-emptying litterbins – a process that would have take several waste collection teams all day to achieve using traditional waste collection techniques
  • Reduced the total amount of recyclable and waste material by 20 per cent in weight
  • Demonstrated the planning and design gains achieved by not having to plan for waste collection vehicles and bin management at each house

 

The basic information shown in “Facts” (below) cover the areas:

  • Norra Hammarbyhamnen/Barnängen (1982)
  • Hammarby Gård (2005)
  • Lugnet/Henriksdalshamnen (2007)
  • Sickla Udde/Sickla kaj (2000)
  • Fredriksdal in (2016)

Seven Self-Emptying Litterbins were added to the system in the small harbour Henriksdalshamnen in 2012.

“The automated waste collection systems used within Hammarby Sjöstad have greatly contributed to the fulfilment of the district’s environmental goals, notably by increasing recycling and reducing heavy traffic. They have also impressed and inspired thousands of national and international visitors to Hammarby.”

Karin Wanngård (S), Mayor of Stockholm

A model for green living

Thousands of professionals have visited Hammarby to learn about the city-led masterplanning, design and delivery process and the Hammarby model for dealing with waste, energy and water that combine to make it such an environmentally balanced place to live, work and enjoy.
