Boskalis Environmental and Inashco JV Wins Attero Contract
- Business & Finance
Dutch dredging contractor Boskalis has just announced that they will process all bottom ash produced by Attero for a period of ten years.
The contract was awarded to ACCN (Ash Cleaning Company Netherlands), a joint venture between Boskalis Environmental and Inashco.
The total value of the contract will be in excess of EUR 100 million over the ten-year period and is partly dependent on the market prices of the recovered metals.
Boskalis holds a 50% stake in ACCN with the results being accounted for as an associate.
Attero’s waste-to-energy plants in Moerdijk and Wijster in the Netherlands produce around 450,000 tons of incinerator bottom ash per year.
ACCN is building a plant at Nauerna in the Port of Amsterdam area to process the bottom ash, based on a washing process developed by Boskalis Environmental.
Once processed, almost all of the bottom ash is suitable for re-use as a raw material, allowing Boskalis to contribute to the circular economy.
The mineral fraction, consisting of sand and granulate, will be used as a freely applicable building material in Boskalis’ civil engineering works.
