AB - 
	Solar drying has become a popular method of sewage sludge processing in Poland over recent years. This is due to the possibility of using a renewable source of energy and the fact that solar dried sludges can be used for energy purposes. Over the last ten years in Poland, almost thirty solar or hybrid greenhouses of sewage sludge have been built. The aim of this work is to present the advantages and disadvantages of the solar drying method of processing sewage sludge. The advantage of using solar greenhouses are the use of renewable energy sources for sludge drying, their low operational costs, the reduced sludge volume, their preparation for thermal utylisation, simple construction and easy operation. The disadvantages are that drying efficiency depends on climatic conditions and season, the need to use additional heat sources, the fact that facilities occupy a large area and the possibility of odors emission released during drying of the sludge.
