The sequential liquidation of the bark and wood waste landfill of the pulp-and-paper enterprise by using the accumulated bark and wood waste is proposed. Theresearches of the samples of bark and wood waste of the prolonged storage (BWWPS), which include the determination of their chemical composition and phytotoxicityrelative to higher plants, are performed. The safety of bark and wood waste by sanitary-hygienic indicators (heavy metal content) is established and thepresence of biogenic elements (nitrogen, phosphorus, potassium), which are necessary for the growth and development of plants, is determined in them. Theabsence of suppression of the growth and reproduction of higher plants when growing them on soils containing BWWPSs is confirmed. The technological schemeof reclaiming material, ameliorators, and organometallic fertilizers based on BWWPSs by their excavation and preparation (crushing, sieving, composting and treatmentwith biogenic elements) aimed at the subsequent use for landscape improving and gardening is developed.
