GREEN HPA AND CO2 LOOP
The aim of the SisAl process is to resolve problem of non-sustainable raw materials, by replacing carbon with secondary aluminium sources (scrap, dross) as reductant for Si production from quartz (SiO2), and in parallel making an intermediate slag which is a perfect precursor for HPA processing.
ABOUT THE SISAL RESEARCH PROJECT
Today Si and HPA are made non-sustainably; for each tonne of Si you make a lot more CO2, plus harmful pollutants. This problem is resolved by SisAl, by replacing carbon with secondary Al for Si production, and in parallel making a slag being a perfect precursor for HPA. If successful in up-scaling, NTNU through a spin-off (licences), SiQAl & Mytilineos (HPA), and CALEF (CO2 looping) will commercialise the sustainable technologies and products.
EIR RAW MATERIALS
SisAL project is funded by the EIT RAW MATERIALS.
The total duration of the project is estimated to be 36 months.
