Taking control of waste collection

How Envac is helping one municipality fix its waste collection costs for decades to come

The client

Järfälla Municipality

“Sustainable development requires a long term view and by choosing underground waste collection we’ve found a long-term solution. By installing the system within the fabric of Barkarbystaden we will have better control of the cost of waste collection over the system’s lifecycle instead of being exposed to price increases set by waste collection companies. We’ll also gain better visibility of our waste collection costs for as long as we use the system, which will help from a budgeting perspective. From an end-user perspective, those who live and work in the area will have a world-class waste collection system that will contribute towards making Barkarbystaden a place that Sweden can be proud of. We look forward to sharing this journey with Envac as we continue to develop the site.”
Crister Bäckström, Manager for Water, Wastewater & Waste at Järfälla Municipality

The brief

Barkarbystaden is an ambitious regeneration project in the municipality of Järfälla, which lies within the urban district of Stockholm.

With plans to build 18,000 homes by 2030 and a commercial centre that will create 10,000 jobs, Järfälla Municipality not only required a waste collection solution that could cater for a large residential and working population, but also one that would support its aim of making Barkarbystaden a truly green city.

Järfälla Municipality also needed a system that would support its overarching sustainability strategy, be fully owned and controlled by the municipality and provide the most economical return over the solution’s lifecycle.

Following a political decision, which stated that an automated waste collection needed to underpin the site’s waste collection strategy, Envac won the contract to become Järfälla Municipality’s waste collection partner.

The project

Referred to as ‘West Stockholm’s new hub’, Barkarbystaden is currently the largest development in Stockholm with aspirations of becoming a district that uses minimal power and manual labour, and that lays the foundations for future sustainable development. It will include:

  • 18,000 apartments across 140 blocks
  • A hospital
  • Secondary schools
  • Higher education institutes
  • Restaurants
  • Cafes
  • Hotels
  • Retail and commercial space

On the development’s completion, Barkarbystaden’s automated waste collection system will be one of the world’s largest municipality-owned Envac installations, transporting approximately 3.2 tonnes of waste from 400 strategically located inlets each day. Collected waste streams will include general waste, paper and plastics.

Järfälla Municipality’s decision to own the system was part of its plan to replace multiple, fragmented approaches to waste collection, which to date have included manual waste collection using traditional waste collection vehicle trucks and deep collection storage vessels. Through Envac, the municipality will have one uniform system that remains underground and delivers cost savings for as long as it chooses to use the system.

The result

By 2030 Envac will have:

  • Enabled Järfälla Municipality to take and retain control of and reduce its own waste collection costs, protecting it from rising waste collection prices as imposed by waste collection contractors
    Helped Järfälla Municipality better manage its waste collection budget by providing a fixed and scalable model over the lifetime of the system
  • Reduced the amount of waste collection vehicle movements and the associated traffic risks and carbon emissions by up to 90 per cent
  • Contributed to shaping and achieving Barkarbystaden’s sustainability goals
  • Helped Järfälla Municipality maximise its aboveground space by taking waste collection underground, allowing it to become a utility similar to gas, electricity and telecommunications
  • Provided a system that handles the waste of the entire population of Barkarbystaden in minutes as opposed to multiple waste collection vehicles making multiple waste collections every day
