A. PROJECT DATA
This project is supported by a grant of the Romanian National Authority for Scientific Research and Innovation, CNCS/CCCDI - UEFISCDI.
Project type: Post-doctoral research
Contracting authority: Executive Agency for Higher Education, Research, Development and Innovation Funding – UEFISCDI
Project code: PN-III-P1-1.1-PD-2016-1093
Acronym: WIR-STAB-01
Contract: 93 from 02.05.2018
Coordinator: University Politehnica Timisoara
The aim of the project is to develop a new technology for stabilization/solidification of MSWI residues that can be scale up to a full industrial scale facility, by applying commonly used technology for dense slurry disposal and storage of slag and ash from coal power plants. The innovative concept is based on using fly ash and desulphurization products related to coal incineration as a binder material to stabilize through solidification process the pollutants (heavy metals mostly) contained in MSWI residues. The treatment of MSWI residues by stabilization/solidification method is rendered to be one of the most applied technologies. This method is used to encapsulate harmful chemical compounds by absorption, hydration or precipitation reactions, by means of using a binder matrix. The aim of this process is to create new compounds in a stabilized form that encompassing the harmful elements, which are non-hazardous or less hazardous than the raw (initial) material.
Project includes a series of experiments for embedding the MSWI residues into the coal fly ash rock matrix with the support of the preview research results. There will be establish a reasonable small scale landfill disposal dimensions, in order investigate the leaching behavior on environmental conditions, during a reasonable period of time. The experimental landfill disposal will be exposed into environment. The leaching and percolation test will be done periodically according to standards for tracking the pollutants concentrations migration into environment.
