Innovative creation technologies for the growth substrate based on the man-made waste – perspective way for Ukraine to ensure biological reclamation of waste dumps and quarries

Abstract

Abstract: This article deals with the problem of man-made waste utilisation, namely, sewage sludge after the biological treatment stage. The current states of the problem in Ukraine and possible ways of its solution are analysed. The connection of research topics with the National Waste Management Strategy of Ukraine is shown. Critical analysis of sewage sludge utilisation technologies was performed. It is proposed to create a growth substrate as an inexpensive and effective alternative to utilise wastes with organic components. The composition of the growth substrate was selected to ensure its functional properties and low cost. The growth substrate was tested using bioindication and further modified by the addition of natural sorbents. The perspectives of the developed innovative technology for biological reclamation of disturbed lands and perspective directions of new researches are considered.
