Products based on renewable raw materials have become increasingly important in recent years. The reasons for this can be seen both in the special properties of these products and in the availability of renewable raw materials. Biogenic fuels and biodegradable plastics (biopolymers) as well as products for degreasing and cleaning metal surfaces (fatty acid esters) are playing an increasingly important role.

1.Basics 1.1 Properties and importance of renewable raw materials 1.2 Possible applications 1.3 Advantages and disadvantages of products made from renewable raw materials 2. Biogenic raw materials: Extraction of fats and oils 2.1 Extraction and processing methods: Splitting of fats to obtain fatty acids (high pressure; low pressure process, 2.2 Possible applications, utilization of fatty acids, transesterification of fats and oils to biodiesel (Konnemenn patent) 2.3 Surfactants based on renewable raw materials, classes, applications . 3. utilization of carbohydrates 3.1. extraction of sugar from sugar beet and sugar cane; 3.2. extraction of starch from potatoes and cereals; 4. polymers: thermoplastics, thermosets, elastomers. 4.1 Bio-based functional and structural polymers 4.2 Production and use of polylactic acid and polyhydroxybutyric acid, 4.3 Polyurethanes from renewable raw materials. 4.4 Biopolymer chitin, possible applications. 4.5 Extraction of natural odorants and flavorings (processes, examples) 4.6 Cellulose-based products for paints and varnishes 4.7 Production and application of microalgae (fuels/food)

5. energetic use of renewable raw materials 5.1. combustion, basics of biomass cogeneration plants 5.2. pyrolysis processes; production of natural gas substitutes (SNG) processes, products 5.3. production of BTL fuels; Greasoline process.Hydrothermal carbonization 6 Biogenic fuels 6.1 Biogas production; biogas conversion, CHP; 6.2 Digestate processing, nitrogen and phosphate recovery 6.3 Biomass potential from residual and waste materials 6.4 Bioethanol production 6.5 Biodiesel production 6.6 Costs and life cycle assessments of biofuels 6.7 Biorefinery: structure, mode of operation, competition with conventional refineries

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

Presentations are prepared on the content listed, which are then discussed by experts. The presentations of the other module participants are also examined orally, as handouts are prepared for the presentations. This allows all participants to prepare for the content of all the other presentations.

• Oral presentation, with written elaboration and oral exam

Knowledge from the fields of general, inorganic and organic chemistry as well as microbiology, thermal and mechanical process engineering plus renewable energies.

Students who have successfully completed this module have acquired detailed knowledge in the field of renewable raw materials. They have basic knowledge of the technologies for the production and processing of products based on renewable raw materials.

Students at Osnabrück University of Applied Sciences who have successfully completed this module have knowledge that is very detailed in areas of the material use of renewable raw materials and knowledge that is based on current developments in energy use.

After completing the module, students will be able to assess the relevance of renewable raw materials and classify them in terms of their socio-economic potential. They will be able to critically evaluate the potential for land use, also with regard to their processing methods

Students of this module can work in work-related contexts that can be applied in various procedures, skills and techniques.
