Due to the increased awareness of global environmental conditions, the market demand for filter application will increase. In Europe the growth in nonwovens is partly driven by European Union (EU) regulations. For example, in 1990 EU regulation 99/30/CE was passed for protecting the civil population against exposure to fine particulates in the atmosphere. The regulation placed a limitation on the amount of PM 10 concentration released in the environment. The PM 10 concentration was limited to 40 µg/m3 in 2005 and this limit will be made more stringent and set at 20 µg/m3 released per day from 2010 onwards. This is expected to present a considerable challenge to many industrial regions.
