Cellulose-based wastes, e.g. protective clothes, cotton, filter
paper, towel paper represented an important fraction of solid low
and intermediate levels radioactive wastes, originated from
peaceful applications of nuclear technologies, and comprise in some
cases up to 40 % of their composition. Many of these wastes have
been identified as "problematic" due to their organic nature as
well as the radioactivity content. A current study explored a new
method for treating and solidifying cellulose-based wastes. One of
the most challenging problems facing mankind is the waste disposal
due to the high production of wastes more than before, creating a
huge environmental problem. The wet oxidative degradation technique
was chosen for destruction and oxidation of these waste categories,
using 35% hydrogen peroxide as an oxidant, before the encapsulation
in a cement matrix. The slurry arising from wet oxidation was
immobilized in Portland cement. Chemical, physical, mechanical and
thermal characterizations of solidified waste forms were evaluated
to fulfill the disposal environmental requirements. This work may
introduce a solution for one of the most challenging solid
radioactive wastes.
