Reducing the Negative Impact of Pulp and Paper Industry Wood Waste Landfill on the Environment by Using the Bark and Wood Waste of the Prolonged Storage

Abstract

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. The
researches of the samples of bark and wood waste of the prolonged storage (BWWPS), which include the determination of their chemical composition and phytotoxicity
relative to higher plants, are performed. The safety of bark and wood waste by sanitary-hygienic indicators (heavy metal content) is established and the
presence of biogenic elements (nitrogen, phosphorus, potassium), which are necessary for the growth and development of plants, is determined in them. The
absence of suppression of the growth and reproduction of higher plants when growing them on soils containing BWWPSs is confirmed. The technological scheme
of reclaiming material, ameliorators, and organometallic fertilizers based on BWWPSs by their excavation and preparation (crushing, sieving, composting and treatment
with biogenic elements) aimed at the subsequent use for landscape improving and gardening is developed.
