The hybrid process ultrafiltration/adsorption purifies latex industry waste water of monomers and solid wastes to the extent that it can be reused in the production process. The treatment costs are slightly under 6 €/m³. Expand…
To date, the stringent requirements applied to inks for use in the rotogravure printing process have precluded the use of more environmentally friendly water-based inks for this purpose. A potential solution is provided by completely solvent-free binder systems based upon acrylates and epoxy resins, which require only limited energy for drying, can be cross-linked under UV light and release only minimal emissions. Further information is contained in the brochure.

The process developed under the project uses ultraviolet (UV) light to break up antibiotics and X-ray contrast agents in the wastewater into harmless components before they enter the sewer system.

The establishment of uniform measuring processes and guideline values for the Ultraviolet Protection Factor (UPF) of items of clothing, together with the analysis of existing textiles, has produced the requisite database for the development of “UV protective clothing”. Accordingly, textiles will be able to make a reliable contribution to the prevention of skin cancer. Expand…
By an innovative modular structure to products and production and a technology, known as Tinting During Filling, the reduction of emissions in water and solvent based products has been reduced in a cost effective way. Expand…
Because cobalt dust is classified as carcinogenic when inhaled, cobalt oxide containing dust generated by waste incineration units has to be, as far as possible, removed from the flue gases. Trials have been made to find out whether high efficiency submicron particulate airfilters are suitable to obtain the required filtration effect. These trials have shown that the filtration effect is very good, durability of the filters, however, is not satisfactory (further information in German). Expand…
During the reaction of the distillation residues of the alkyl chlorosilane synthesis with dry gaseous ammonia in a nonpolar organic solvent (dichloromethane, tetrahydrofurane) a mixture of polysilazanes and ammonium chloride develops. By distillation of the solvent up to 70 % concentrated polysilazane solutions can be received. The synthesized polysilazane solutions were used for the production of ceramic infiltration, fibre composite, composite and attached materials and thus the suitability of the manufactured products for high quality ceramics was shown (detailed information in German).
The method developed is based on elements of textile engineering (pull-drill method). The basic principle involves the use of card sliver. The feasibility of the method was successfully demonstrated on the laboratory scale. The availability of natural-fibre-reinforced granulates potentially provides access to a large market, in particular in the field of injection moulding / extrusion.

PDF-IconUse of long-fibre granulate with natural fibre reinforcement for the production of environment-friendly fibre-reinforced foam materials
In future, the waste-intensive compression moulding of non-woven fibres will no longer be the only option available for the production of technical components of natural fibre and synthetic material composition. This brochure contains information on the patented pull-drill process, which allows the continuous production of long natural fibre-reinforced granulates at an attractive price. A significant application will be vehicle construction. Further information is contained in the German language brochure.
