nsequence of the research results obtained being put into industrial practice. In the wastesector, onsorship measureswere,aboveall,abletoachievetheavoidance/utili- sation of various kin$ of hazardous wastes - spent acid (8,0 ),solvents (1 0,0 tpa), chlorinated hydrocarbons (2,0 tpa) and electroplating sludge (5b tpa). In addition, the uti- lisation of 2,0 tpa plastic waste was also achieved. In the wastewater sector, the implementation of research results has,'for example, made it pos- sible largely to avoid organochlorine wastewater loads in 3% of all pulp production. Further- more, numerous plants have been installed for tertiary treatment of wastewater to remove non-biodegradable substances, such as heavy metals, amines, phenols and salts. Similarly, plants for conditioning and reutilising process water (.. sulphuric acid) and for recovering constituents of wastewater (.. sizing agents, heavy metals) have been put into,operation. In the exhaust air sector, 4% of all primary lead production can,for exam le, be converted toa new, low-emission production process in future, thus avoiding the annua~emission of 2 lead and 2,5 SO2. Furthermore, numerous plants have been installed for the recovery of so-cal- led plasticisers (.. phthalates). Plants for end-of-pipe exhaust air purification have been con- structed at refuse-fired combined heatin and powerstations, infoundriesand by food produ- cers. Moreover, low-solvent paints havezeen developed and marketed as low-emission pro- ducts. Thus, the success of the sponsorship of application-oriented research in the field of environ- mental technology to date is characterised both by hi rate of implementation of the research results and by the remarkable economic and ecoyogical effectiveness achieved. 2 Duration: 0 0.8 - 3 . 0.8 0 VQ8 Subject: Influence of economic and technological development on emission and immission trends Research centre: Fichtner Beratende lngenieure GmbH & Co.
