Extensive work on historic ground
Vinterviken in Stockholm, Sweden’s Aspudden neighborhood 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 a comprehensive decontamination was deemed necessary.
The winning contract went to Fortum Recycling and Waste, one of Fortum Group’s full-service subsidiaries that provides recycling and waste management services for the public and private sectors. The work – consisting of demolition, decontamination and restoration – started in summer 2019 and took approximately a year to complete.
Specialists in hazardous waste management
One of the many reasons that Fortum Recycling and Waste was selected: the company’s 50-year history of specialising in hazardous waste management. Decontamination was going to be one of the most difficult 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. 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.
