Environmental protection ‐‐ a permanent challenge. Through the intensive investment activity of municipalities and of the chemical and related industries in the past twenty years it has been possible to greatly reduce the extent of environmental pollution which rose as a result of the rapid urban expansion and industrialisation of the 1950's and 60's. However, a more thorough protection of river and sea waters cannot be achieved merely through the further sophistication of waste‐water technologies. More importantly, every possibility for reducing the quantity and pollutant content of waste‐water must be fully exploited. Such possibilities lie in the recycling of processing water, in the integration of environmental protection into the process itself, as well as in the appropriate redesign and modification of the processes. The various fields of activity, especially those particularly rewarding to the process engineer are examined and numerous possible directions are offered. Six technical examples, which have been applied in practice, serve as illustration.
