Compressed carbon dioxide represents a more environment-friendly substitute medium for textile cleaning. In tests, compressed CO2 has achieved comparable results to tetrachloroethylene, in terms of cleaning properties and textile durability. However, specific dry-cleaning detergents which are suitable for use with CO2 have yet to be developed for some types of soiling. Expand…

Bio-technological processes for the production of chemicals are usually classified as more eco-friendly than conventional chemical-technological processes. This study examines basic and refined chemicals which are produced on a large scale with chemical-technological procedures. At the example of acetone/butanol, propane-1,3-diol, vitamin C and adipic acid ecological, economical and legal aspects of the application of bio-technological procedures as well as their restraints are determined. Further, the report contains indications for the performance of publically promoted demonstation procedures (detail information in German). Expand…

Sulphonic acids from wastewaters discharged by the chemical industry may cause problems in the preparation of drinking water from bank filtrate. Investigations have shown that, in the presence of natural organic water constituents, the capacity of activated carbon for multiple sulphonated compounds is inhibited. In consequence, the early penetration of these compounds may be anticipated under actual filtration conditions. Expand…

The cellulose-carbamate process has been used for the development of a spinning technique which is capable of competing with the conventional viscose process. Since no toxic substances are involved and the chemicals used are recirculated, this technique renders end-of-the-pipe technologies superfluous. Expand…

Faced with a shortage of fossil resources, carbon dioxide may change from being a "problem substance" to become a valuable resource. The publication illustrates the potential of CO2 to cover the chemical industry's demand for carbon. Also, CO2 can be employed as an energy store. At the same time, research is conducted as to how the chemical industry's greenhouse gas emissions may be curbed by increasing energy efficiency and the use of functional solvents.
