The present study examines the absorption capacity of five different types
of materials for oil spills clean up. The absorbents were a commercial cell
ulosic material from processed wood, a commercial synthetic organic fiber f
rom polypropylene and three commercial types of local expanded perlite from
the island of Milos. The absorption capacities of the above materials were
evaluated in a wet as well as a dry environment with different types of pe
troleum products. The results showed that commercial types of perlite, in s
ome cases, have absorption capacities comparable to natural and synthetic o
rganic materials used for clean-up applications. The enhancement of the hyd
rophobic properties of perlite can result in better performance in a water
bath. The nature of the spilled oil proved to play an important role in the
selection of the proper absorbing material. Overall, the results suggested
that partial substitution of commercial synthetic sorbents by mineral mate
rials widely produced in Greece for oil spill clean-up operations is possib
le, given their friendliness to the environment and their local abundancy.
