Extensive work on historic ground
Vinterviken in Stockholm, Sweden’s Aspudden neighbourhood, holds a special place in many residents’ hearts. It is not only one of the city’s most well-known parks, but also an area of great historical significance as it was once home to Alfred Nobel’s famous factory for developing and testing dynamite.
However, a study commissioned by the City of Stockholm revealed that the areas surrounding the former factory and the nearby lakebed were some of the city’s most contaminated. There were such high concentrations of heavy metals and contaminants in the soil that comprehensive decontamination was deemed necessary.
The winning contract went to Fortum Recycling and Waste, one of Fortum Group’s full-service subsidiaries that provide recycling and waste management services for the public and private sectors. The work – consisting of demolition, decontamination and restoration – started in the summer of 2019 and took approximately a year to complete.
Specialists in hazardous waste management
The company’s 50-year history of specialising in hazardous waste management was one of the many reasons that Fortum Recycling and Waste was selected. Decontamination was going to be one of the most challenging parts of the job, requiring excavation of large amounts of contaminated soil and dredging of the lakebed, all while ensuring the safe disposal of the contaminated material.
To minimise unnecessary transport, the contaminated material was sorted and classified on the spot at the Vinterviken project site. The hazardous material was sent to Fortum Recycling and Waste’s in-house waste management plant in Kumla, south of Örebro. This plant is only one of few in Sweden specially classified to safely manage and dispose of hazardous waste.
Out with poisonous heavy metals, in with midsummer flowers
Following excavation and decontamination of the area, Fortum Recycling and Waste worked to restore the entire green space to its former glory. In addition to the significant work of planting flowers, trees and grass, Fortum Recycling and Waste installed outdoor furniture, restored bike paths, and upgraded the area’s lighting.
With the help of a professional gardener, Fortum Recycling and Waste planted:
- 15,000 m3 of grass turf
- 500 m3 of grass seeds
- 1,100 bushes
- Approximately 1,500 plants and flowers
- 100 trees
The new and improved Vinterviken got ready for public use by the summer of 2020, allowing Stockholmers to again have picnics in the grass, swim in the lake, and enjoy the park’s natural beauty – free from contaminants and pollutants.
