Dietary protein reduction in combination with simultaneous supply of limiting amino acids reduces environmental load with nitrogen and helps to save feeding costs. To take full advantage of low protein diets, the energy supply must also be taken into account. With high protein diets, excess absorbed amino acids are converted into nitrogenous waste which is excreted through urine and faeces into the environment. The goal of the present study is to investigate the effect of a crude protein reduction under different energy levels with consideration of the ideal-protein on zootechnical and slaughter performance, as well as carcass characteristic parameters of fattening pigs.

Development on 100% bio-based NFC regarding formulations (e.g. fiber types) and processing (e.g. injection moulding and extrusion are in the focus) will be continued. Processes for the post-treatment of moulded parts by brushing, painting, coating, printing will be further evaluated. Extension of the permanent accompanying literature study with reference to new bioplastics and production of filaments for 3D printing.

The availability of large scale storage solutions is considered to be key for establishing the highly anticipated ‚energy change‘ and hence of central importance for policies, industry, research, and other branches in order to secure energy supply. Underground gas reservoirs offer enormous storage capacities for green hydrogen when compared to surface based storage solutions. The current project aims at the investigation of potentially occurring, hydrogen-driven metabolic reactions which can be catalyzed by microorganisms dwelling in natural gas reservoirs. Potential responses of the microbial community endogenous to formation water samples will be analysed with respect to hydrogen exposure. Adequate formation water samples will then be selected and used for high-pressure storage experiments with hydrogen admixtures mimicking realistic reservoir conditions.
