and apricot kernels. In addition, coconuts are not possible for use in Kazakhstan,
since there is no raw material base and as such a relatively expensive raw
material.(Antoszczyszyn and Michalska 2016).
4. Although apricot kernels and seeds of other fruit trees a priori look like
afdvantageous starting materials thiks material may secrete a large amount of
HCN. Further, as a rule, when obtaining AC from the seeds of various fruits,
chemical methods are used for activation, which is harmful both for a person
working in production and for the environment as a whole.
5. The preparation of AC from traditional raw materials such as bituminous coal,
phenol-formaldehyde resins is an economically expensive and environmentally
harmful production. This raw material is non-renewable, and its extraction is a
laborious and harmful process.
6. The use of wood as a raw material for the production of AC is a laborious process,
as it often requires grinding and chemical preparation of the raw material for
carbonization. The main task of replacing wood with more accessible material is
that a long period is needed to restore and grow large-scale forests, which are cut
down annually as a result of the widespread use of wood.
Cost-effective ACs made of new materials are supposed to find its application
in various industries, such as processes for cleaning of wastewater, air, and the
environment as a whole. Hence, despite the low ranking of the method based on
Miscanthus straw, this method should obviously not be left out of consideration.
