Sewage sludge: problems and opportunities for their use in agriculture

Abstract

In world practice, there are many waste processing technologies. However, the use of most of them leads to an increasing accumulation in nature of gaseous, liquid and solid components, causing irreversible damage to the environment. In the Republic of Belarus, the problem of recycling wastewater sludge from industrial enterprises is quite acute due to the increased content of highly toxic substances in them. In this regard, there is a need to develop rational ways for their safe processing.
