The environment and its protection are among the most followed topics of today. Logging using forest machines is closely associated with the hazard of service fluids spills and their negative impact on the forest ecosystem. Engine oils represent the highest share of all service fluids used in forest machines. In the present study we tested engine oil fouled during regular operation of the forest machine. Synthetic, as well as natural sorbents can be used for a quick and effective removal of engine oil spills. Procedures in accordance with the Standard Test Method for Sorbent Performance of Adsorbents (ASTN F 726-2006) were used in the present study, while the maximum sorption capacity of natural sorbent samples like leaves residues (Fagus sylvatica), saw dust from logging (Fagus sylvatica), needles (Pieca abies), moss (Ceratodon purpureus) and soil was tested to remove engine oil spills (Mogul M7 ADS III). The research was focused on natural sorbents due to their availability on site of the possible spill. The moisture of the environment was 80% ± 10% representing the approximate forest moisture. We supposed that the sorbent with the largest measured surface will have the highest capacity. The results show that the most effective sorbents are needles, moss and leaves, what is associated with measured surface and porosity of those materials. The obtained results, based on the above mentioned standardised method, meet our expectations.
