Abstract
Fractions of Zinc, Chromium and Cobalt in Municipal Solid Waste Incineration Bottom Ash
Highlights
The amount of municipal solid waste will be increasing in the coming years, mainly due to the progressive urbanization and living standards
municipal solid waste incineration (MSWI) bottom ash is the main solid residue from the waste incineration. It comprises even 20–25% of the waste introduced into the incinerator (Huber et al 2021). It is a potential source of environmental threat, due to the content of heavy metals and other harmful pollutants (Huang et al 2020)
The aim of this study was determination of fractional composition of zinc, chromium and cobalt in particle size fraction ≤2mm, since this fraction accumulates the most of heavy metals contained in MSWI bottom ash (Chimenos et al, 1999)
Summary
The amount of municipal solid waste will be increasing in the coming years, mainly due to the progressive urbanization and living standards. 90%, which translates into the mass reduction by 70% (Vaitkus et al 2019). This process is currently the main approach to municipal solid waste management in Europe (Minane et al 2017). MSWI bottom ash is the main solid residue from the waste incineration. It comprises even 20–25% of the waste introduced into the incinerator (Huber et al 2021). It is a potential source of environmental threat, due to the content of heavy metals and other harmful pollutants (Huang et al 2020). In Europe about 50% of countries are utilizing the processed bottom ash as a construction material (Vateva and Laner 2020)
