Sodium silicates are mostly used for the production of detergents. Moreover, they are needed in big volumes as basic product for the manufacture of silicic acid as additives for rubbers and plastics and cracking catalysts for the petro-chemical industry.

Synthesis gases are mixtures from hydrogen and carbon monoxide. Raw materials are solid, liquid or gaseous fuels, which react under additivation of oxygen and / or steam at higher temperatures. Often the production of synthesis gas is a very economic recycling process of residues, which can provide the basis for basic chemical products, e.g. methanol.

Quality targets are reference values and guidelines with regard to a particular protected asset and serve as a benchmark for the quality of surface waters.

Using the LCA instrument the FEA research project 'LCA for Graphic Papers' answers key questions about the production and optimisation of graphic papes and the products manufactured with them.

There is often talk that environmental protection is no longer an issue of public debate. I believe that this is exaggerated. Unemployment or domestic security may certainly be more topical than environmental protection.

It has increasingly become accepted in recent years that ecosystems can only be managed sensibly if they are perceived and protected in their entirety. To this end, 12 principles for an ecosystem approach and 5 points of operational guidance have been elaborated in the framework of the Convention on Biological Diversity. They have not been applied to a marine ecosystem as yet.

Tires for commercial vehicles are optimized to be both fuel efficient and long lasting. A low noise design provides generally little incentive to buy. The noise reduction potential of tires for commercial vehicles is not sufficiently used as the comprehensive test of 32 tires shows.

Aerosols in the atmosphere have the potential to seriously affect the quality of our environment. Particles of less than 10 micrometers may after inhalation cause adverse effects on health. In addition to direct effects on the health of mankind, aerosols also affect the climate. Aerosols scatter and absorb light as a result of which they directly affect the radiation balance of the earth.

The model ONERIS (MOdelling Nutrient Emissions in RIver Systems) was developed and applied to estimate the nutrient inputs into river basins of Germany by point sources and various diffuse pathways. the model is based on data of river flow and water quality as well as a geographical information system (GIS) which includes digital maps and extensive statistical information.

During summer and fall 1998, 75 sample takers and 20 employees of laboratories of 26 institutes measuring emissions in Germany and Switzerland estimate the uncertainty of measuring results of 5 selected VDI-standard emission measuring methods.
