research and innovation programme under grant agreement No 945098.

WP5 Recap and Chief Achievements
Reminder of the objectives

 Implementing geopolymers and related alkali-activated materials as
  mineral binders.
 Fulfilling technical and economic requirements related to RLOW:
      robustness regarding waste variability,
      easiness of implementation and operation (e.g., mobile units),
      capacity ranging from low to large volumes and limitation of secondary waste,
      reduction of disposal costs by minimization of volumes (pre-treatment and waste loading).

 Leading to final waste showing properties and performances compatible
  with safety and technical requirements related to disposal but also
  prolonged storage and transport.
    Disposability assessment and demonstration is a key issue and challenge of WP5.

  completed by PREDIS Partners and EUG (collection of
  information about the RLOW and the way they are processed).
 We are welcoming further responses (online or PDF form).
 4500 m3 of RLOW identified so far, mainly oils and solvents.
 In the WP, use of reference surrogates : ‘simple’ oil (Nevastane
  EP100 and Shellspirax), TBP, Dodecane, Scintillation
  cocktails (Ultima Gold AB and INSTA GEL), and possibly waste
  of interest in national contexts.
