While incineration established itself as the best treatment option for municipal and industrial waste, with around 90 Mt/y of waste treated in EU incinerators, the management of its main residue, that is bottom ash, rapidly became a crucial point in the waste chain.
With 80 – 85 % (w/w) of mineral fraction and a valuable 10 – 12 % of metals, the recovery of residual useful components from bottom ash is a complex challenge for EU (20 % w/w of metals contained in bottom ash are not yet recovered), that may lead to important technical, socio/economic and environmental outcomes.
BASH-TREAT objectives are:
1) a complete assessment of EU state-of-the-art bottom ash treatment options considering technical/economic/environmental viewpoint;
2) an optimization of the exploitation of the refining treatment of the fine fraction deriving from full-scale trial tests;
3) the development of EU guidelines for the enhanced and innovative full valorisation of valuable components of bottom ash (metals and mineral fraction).
What is expected from BASH-TREAT is a database with information about performances, results, characteristic of bottom ash treatment in EU and suggestion for process improvement. The validation of the data via full-scale treatment plant plants.
The development of new innovative technologies for the treatment of the fine fraction in a lab scale process. The technical, economical and environmental assessment will be performed for all the aspects faced in the project. An international, interdisciplinar and intersectoral consortium composed by two universities, one research center and two industrial partners with provide different and specific expertise-competences will face BASH-TREAT research activities.
