sewage sludge		 Summary: The possibility of using a mixture of production wastes, such as sewage sludge and waste from the timber industry complex, in the form of a mixture of bark with sawdust for the preparation of a soil substrate, has been investigated. The substrate can be effectively used for reclamation of municipal solid waste disposal facilities. In the course of the study, the influence of the ratio of components in the substrate and species of fast-growing plants on seeds germination was studied. Four varieties of seeds were studied, two of them germinated. Two varieties of bulbous seeds did not germinate. The maximum germination indices of radish and buckwheat seeds, 108 mm and 140 mm, respectively, were found on the substrate at a ratio of sewage sludge of 60% and a mixture of bark and sawdust of 40%.
