Dyes are a group of pollutants of growing concern
due to the toxic effects associated with their presence
in the environment and their recalcitrant character
to the degradation by using the conventional systems
wastewater treatment plants are operating with. In this
regard, biochar, considered as a by-product derived
from the biomass thermochemical conversion process,
is positioned as an attractive alternative due to the
physicochemical properties, including the surface area
and the functional groups, exhibited by this absorbing
material. In the current work, dye definition, classification,
properties and the adverse effects produced in
the aquatic ecosystems are presented. Additionally, the
commonly used water treatment systems are described,
focusing on the use of biochar as an alternative technology.
Finally, the cost-efficiency relation and the biochar
reusability capacity during the pollutant removal
process are covered. In this work, new horizons concerning
the contribution to the circular economy and
the long-awaited sustainable development are opened.
Key words: biochar, dyes, removal, reusability, sustainable
development, wastewater.
