Vattenfall realizes heat transfer station and upcycles 104,656 kilos of waste with a circular facing brick

Amsterdam October 1st, 2022 – In the Hakfort district (Amsterdam Southeast), Croonwolter & Dros realized, together with construction company J.P. van Eesteren, commissioned by Vattenfall and designed by architect Willem Schutter, a heat transfer station as part of the district heating network in the municipality of Amsterdam.

In the masonry facade, no less than 104,656 kilos of construction, demolition and industrial waste is given a new life by using StoneCycling’s WasteBasedBrick.

Energy supplier Vattenfall has a clear goal: to enable fossil-free living within one generation.

Marc van Gestel: “District heating is comfortable and environmentally friendly heat, which comes from a combined heat and power system that uses virtually no extra gas. In this way, residents and companies in Amsterdam Southeast already emit 62% less CO2 in 2021 compared to gas-fired central heating systems. This will improve further in the coming years through the use of new, sustainable heat sources.”

Circularity is very important for energy company Vattenfall. The heat transfer station is therefore designed as circular as possible with a reusable steel construction, reusable wooden beams, a roof covered with grass and a facade consisting of brick containing 60% waste.

“At StoneCycling, we are pleased that sustainable construction is becoming an increasingly important precondition for construction projects such as this heat transfer station from Vattenfall. Debris from construction, demolition and industrial processes is one of the largest waste streams in the world and the construction sector is also responsible for a third of all CO2 emissions in Europe. That is why we are proud that these parties are leading the way with us on the road to circular construction,” said Ward Massa, CEO of StoneCycling.

“At the same time, we excavate tons of raw materials every year to make the building materials that make up our cities and infrastructure. Major excavations often destroy landscapes and ecosystems; basic raw materials such as building sand are therefore becoming increasingly scarce.”

Architect Willem Schutter approached StoneCycling in the autumn of 2018 with the request for a circular brick. That was the WasteBasedBrick Orange with 5% WasteBasedBrick Nougat bricked through it.

Schutter about his choice: “The preference of local residents for brick, the circularity, my wish to construct a building as much as possible from one material, all these aspects come together in a functional building that derives its character from this special stone, unprocessed or cleverly sawn, detailed as a grid, added in color in a fixed pattern. A landmark in the road pattern of Amsterdam-Zuidoost. A haven in the neighborhood.”

Today all parties gathered during the open day of the heat transfer station, to celebrate the realization and cooperation. In this way we are taking another step towards making sustainable building the standard.
