Continuative utilisation of the material potential of molasses and molasses draff for the production of natural flavourings – here 2-Phenylethanol: Bioprocess optimisation – Pilot Operation (Part 4)
The result is that pervaporative membrane separation reliably removes toxic products of metabolism from the culture broth during fermentation. In order to obtain sellable products, however, an additional processing step is necessary in order to better separate the individual hydrophobic materials (2-Phenylethanol and 2-Phenylethylacetate) in the permeate.

A high level of energy input has to date been required for the moulding and welding of packaging made of cardboard composite material for liquid and soft foodstuffs. It is possible to reduce environmental carbon dioxide emissions by more than1000 tonnes per year through energy optimisation of these processing procedures. The adjustment also entails a lower capital expenditure.

Development of a biotechnological technique for the recycling of fats and fat-containing waste products of the foodstuff industry using fat-processing yeasts
Because of its wide spectrum of substrates, a genetically modified strain of the yeast Yarrowia lipolytica was shown to be suitable for use in the conversion of fat substances for the fermentation of citric acid. The resultant citric acid-based solution can be used for cleaning and as an environmentally-friendly plant protection agent.

The high-speed technology developed has a significantly better energy consumption and throughput speed than conventional machines. Another advantage is the throughput range, as the machine can operate in high-speed mode as well as in the standard processing mode.

Tests of the heating of plastics by means microwaves were conducted. In comparison with the infrared method, the depth of penetration in the material is considerably greater, resulting in a more uniform heat distribution as well as shorter heating times, since no equalisation through thermal conduction is required.

Development of an enhanced value chain through process-integrated environmental protection in the processing of plant raw material using the example from potato starch manufacture: Breakdown of plant cellulose using electrical high voltage impulses and enzymatic treatment (Part 2)
The method of cellulose breakdown using high voltage impulses was successfully applied during the processing of plant raw materials. It has a positive influence on the diffusion and separation processes as well as the hydration capacity and cell content extraction process. A process which does not require additional chemical/biological substances makes this low energy physical method a viable basis for the development of an environmentally-friendly process.

Development of an enhanced value chain through process-integrated environmental protection in the processing of plant raw material using the example from potato starch manufacture: upscaling and trialling of a plant for the production of high voltage impulses and the development of a procedure for [beta-]glucan production (Part 1)
Good results were obtained for a method of breakdown of plant cells with high voltage impulses, avoiding the need for complex and costly processing stages. The marketing of the extracted beta-glucan is facilitated by the fact that gelation and filming, as well as chemical modification, is possible.

Development of process combinations for the recirculation of water and materials in the processing of vegetable raw materials, based upon the example of potato starch production
The optimisation of starch production from potato tubers is closely associated with the improved breakdown of potato cells. A combination of high-voltage electrical impulses and enzymes has proved to be particularly effective for this purpose. By this method, the consumption of water and energy has also been significantly reduced.

Early detection and ensuring the conformity of isocyanate-containing, functional layers (Part 1 und part 2)
During the curing of the laminates the influences of the lamination partners, adhesive type sand climatic conditions (temperature, humidity) on the velocity of the isocyanate decrease and the amine migration out of the laminate was investigated. From it a rapid method using visual detection of the migration of primary aromatic amines was developed.

Eco-efficient fertilisers – Development for the minimisation of nitrogen emissions in water and air
The German language brochure describes three types of eco-efficient fertilisers, which provide plants with essential nutrients such as nitrogen, potassium and phosphorous, in accordance with their requirements. The use of these products allows the application of fertilisers in the agricultural sector to be reduced, while minimising nitrogen emissions in air and water at the same time.
