The article reviews the progress on the investigations of utilisation of organic waste published in ?Biotechnologia? journal. This article outlines the current biotechnological methods and discusses especially the nitrification and denitrification processes on the municipal and industrial sewage in biological and chemical station, the processes of biodegradation of solid waste, the problems of enzymatic transformations of lignocellulose, and the estimation of reproductiveness of earthworms raised on composts of town and agriculture waste and other organic substrates. Furthermore, the problems of cellulose and hemicellulose bioconversion to ethanol, the biological method of sewage treatment using nitrification and denitrification processes, the bioutilisation process of the organic waste in fermenters of different construction, the biodegradation of petrochemical sludge and the enzymatic hydrolysis of waste are the subjects of intensive investigation.
