Zusammenfassung:	PCT No. PCT/EP95/01028 Sec. 371 Date Oct. 21, 1996 Sec. 102(e) Date Oct. 21, 1996 PCT Filed Mar. 20, 1995 PCT Pub. No. WO95/26487 PCT Pub. Date Oct. 5, 1995The waste gas accumulating in the drying of products containing volatile ingredients is cooled, the condensate obtained is subjected to crossflow membrane filtration and part of the cleaned waste gas is returned to the drying process. The concentrate obtained is put to a material, thermal or other use. The both effective and economic process is suitable for eliminating the aerosols, particularly the organic aerosols, present in the waste gas.
