The problem of separated sludge in the chemical industry is very complex and requires a comprehensive understanding. Technology (solidification) used in HIP-Petrochemicals in the plant for sludge dehydration is excellent and based on many years of experience we can say that with the process we can obtain solidificate that can be disposed in the open area. In this the dehydrated sludge has no negative and detrimental impact on the environment (due to the laboratory proven stability) and hydrophobicity, except it requires a warehouse. There is a possibility that the solidificate can be used for building materials. Because of the enhanced features, of the newly obtained solidificate it can be pointed out and concluded that an environmental and economic problem can be solved with a significant financial effect and marked component of environmental protection and sustainable use of waste.
