Abstract The paper is devoted to the study of the use of wood waste as improvers engaged in the reclamation of oil-contaminated lands using bioremediation. Wood waste can act as carriers for biological products and mulching materials that optimize the harsh climatic impact on soils cleaned from oil products. At the example of using pine sawdust of 1.0-1.5 cm fraction for biological purification from oil pollution in laboratory conditions, it is shown that the increase in oat seed germination is 6-28% compared to the introduction of a biological product by sprinkling. At the same time, it was found that fine-grained pine sawdust negatively affects bioremediation, due to accelerated decay of wood, accompanied by the release of toxic components. The use of wood waste in the reclamation of oil-contaminated Arctic lands will eliminate their expensive transportation to legal disposal or burial sites and involve them in soil restoration processes.
