The Escherichia coli model process described in the recommendation also makes it possible to characterise the biological performance of a system. The standardised process aims to determine the performance of bioreactors, in particular single-use bioreactors, and to evaluate their suitability for microbial applications. Since microbial processes place high demands on the bioreactor system with regard to oxygen transfer, this is of particular importance; another important parameter is heat removal. The associated Excel tool offers the possibility of a standardised evaluation, so that a comparison across bioreactor systems is possible. Calculations, e.g. of the volumetric mass transfer coefficient, will be performed automatically after input of the raw data. Recommendation and Excel tool were developed by the "Single-Use Microbial" working group of DECHEMA's expert group "Single-Use Technology in Biopharmaceutical Manufacturing".

Raw Water – Process – Waste Water
Global changes in water availability and the manifold regulatory frameworks have already prompted many companies to develop ambitious strategies to improve their water usage efficiency. This requires a combination of know-how and process technology, embedded in integrated industrial water management solutions.
Due to the high innovation potential of an integrated industrial water management the ProcessNet Subject Division Production-Integrated Water/Waste Water Technology has developed a position paper to highlight the trends and perspectives in industrial water technology.
With this 2nd edition of the Roadmap the ProcessNet subject division Chemical Reaction Engineering addresses the general trend that Chemical Reaction Engineering is directly defining product quality and product properties and, thus, is getting directly involved in the development of innovative application characteristics of products. To an increasing extent Chemical Reaction Engineering is also a key for the process and product development of industrial sectors outside the chemical industry such as energy technology or automotive engineering. Chemical Reaction Engineering is not anymore only devoted to understand, design and optimize chemical reactors in terms of yield, energy and efficiency. In addition, it is a key enabler for product innovations and new business concepts through e.g. product by process approaches or modular plant concepts.
All the aspects mentioned before are considered now in the 2nd edition of the roadmap including case studies, technical chapters and an outlook updated accordingly.
The present White Paper „Modular Plants“ was developed in the temporary ProcessNet working group „Modular Systems“ in a close cooperation between industry and research institutions. It provides the current state of the joint efforts to improve the modularisation of plant technology in the chemical industry. The paper calls for a standardization of the nomenclature for modular production concepts to provide the basis for a wide industrial application of the technology. It points out obstacles but also possible development paths of modularisation and weighs its strengths against risks. Furthermore, research needs and funding actions are identified that are necessary for the further implementation of modular system concepts. A translation of the text into German is planned and publication should be done at the same place.Download as PDF file (1062 kB)

Today, single-use technology is used routinely in biopharmaceutical development and manufacturing processes. Besides many advantages, the available single-use systems still have limitations. One of the most cited disadvantages is the risk for release of potentially toxic or inhibitory substances, so-called leachables from the plastic bags. The bags are typically made of multi-layer thermoplastic films. Until now, no standardized cell culture test was available to identify critical bag films at an early stage in process development. To meet this need, a sub-team of the DECHEMA temporary working group "Single-Use Technology in Biopharmaceutical Manufacturing" developed a standardized cell culture test that would enable the early identification of non-satisfactory films for cultivation of CHO cell lines in chemically defined culture media.Download as PDF file (768 kB)
