Wednesday 10 May - ISCOWA seminar and tour of Blue Phoenix Group Ash Washing Plant

Together with WasteBuild Zero and Blue Phoenix Group, ISCOWA is organising an interesting event related to Circularity in Construction on 10th of May at the NDSM-wharf, Amsterdam. The morning will begin with inspiring presentations, and after lunch, we will visit Blue Phoenix Group’s ash washing plant to see how incineration bottom ash is turned into valuable raw materials. Below you can find more detailed information about the event.

ISCOWA members can attend this seminar for free and get a 50% discount on registration fee for the WasteBuild Zero conference (discount code is given after you have registered for this seminar).

For non-ISCOWA members the registration fee for our event is 75 € (incl. the technical visit). In case you just want to join the seminar-session at NDSM, the fee for that is 45 € (for non-ISCOWA members.) Please find below the preliminary agenda of the event.
