120 From Poland: The Textile Research Institute, Lodz 5-8 Polish dye-houses (these have been appointed) 2-3 producers of textile dye-stuffs and/or auxilliaries (these have been appointed) From Denmark: DTI Clothing and Textile Institute for Product Development VKI-Institute for the Water Environment Expected environmental improvements The introduction of improved recipes, processes, chemicals and dye-stuffs will lead to a major improvement of the environmental impact from the Polish textile industry. Special focus will be put upon substances such as: • Dye-stuffs containing heavy metals • Dye-stuffs with low fixation rate • After chroming processes • APEO containing detergents • Formaldehyde containing chemicals • Cationic surface active agents
To illustrate the order of magnitude of the problems, figures from 13 of the companies visited during the technology transfer programme, showed a mean consumption per company of 49 tons of dye-stuffs, of which around 40% ends up in the waste-water, and 24 tons of detergents, of which the major part was revealed to be APEO-based, and which all ends up in the waste-water. Although it is the aim of the project to improve these and other figures considerably, a quantification is however not possible at present. Project status The project application was filed late 1995 and for different reasons, was delayed until 1997. It was approved in 1997 by the Danish Environmental Protection Agency. The project is expected to commence in 1997. 121
