// Inashco joint venture awarded bottom ash processing contract by Attero
Rotterdam, 2 februari 2017
Inashco announces, together with Royal Boskalis Westminster N.V. (Boskalis), that it 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. Inashco 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 in total around 450,000 tons of incinerator bottom ash per year. ACCN is building a state-of-the-art 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. The mineral fraction, consisting of sand and granulate, can be used as a freely applicable building material in Boskalis' civil engineering works. The valuable and rare metals will be recovered with a technology developed by Inashco and will be marketed as commodities by Inashco. In this way parties contribute contribute to the circular economy.
The Boskalis – Inashco combination provides an integrated solution and takes care of the washing and processing of the incinerator bottom ash on behalf of Attero. Furthermore, the agreement enables Attero to meet its Bottom Ash Green Deal obligation to the Dutch government.
