The training of the personnel on subjects of preveting pollution in the source constitutes an important part in the pratices of pollution prevention. It should be noted that by having been completely informed, having understood all the processes, handling properly the equipment, etc, the environmental performance of the industry is ameliorated, the required chemical agents, water, auxiliary materials and energy are minimised, and the working conditions are improved.

The raw materials that are used in an industrial plant must be checked. The supplier owes to provide the required information, so that the dyeing industry to be in place to evaluate the products using environmental criterias. Usually, the suppliers give only technical characteristics of fabrics or fibres. However, the provided information should also include the chemicals used in the sizing process and the metals and biocides that the raw material contains. These components are transported through the whole production process and contribute to the total polluting load of the liquid waste.

A management system for the stock can be used in order to avoid needless and useless materials. Moreover, the use of suitable management techniques of chemical and auxiliary materials contributes to the minimisation of the required chemicals, water and energy, whereas the industry policy complies with the legislation. A similar result is achieved by using qualitative control systems and making regular and preventive maintainance of the equipment.
