Rhodopsins as an alternative to photosynthesis

For numerous species of living organisms, the climate crisis will lead to environmental conditions that they will not be able to survive. Microalgae could fare differently, as a study by GEOMAR Helmholtz Centre for Ocean Research Kiel, the University of Würzburg and the University of East Anglia (UEA) has now shown. According to the study, the unicellular organisms can adapt to nutrient deficiencies, such as those to be expected in warming seas, with the help of a light-driven proton pump.

IIASA (2023): Feeding climate and biodiversity goals with novel plant-based meat alternatives

An international research team led by the International Institute of Applied Systems Analysis (IIASA) also concludes in the study, published in the journal Nature Communications, that restoring land spared from livestock production when meat and dairy products are replaced with plant-based alternatives could provide additional climate and biodiversity benefits, more than doubling climate benefits and halving future declines in ecosystem integrity by 2050. The restored area could contribute up to 25% of the estimated global land restoration needs by 2030.

BASF: Millions for new fermentation plant

Bacteria and fungi have long been important tools for the chemical company BASF to make the chemical industry more sustainable. With their help, renewable raw materials such as glucose can be converted into bio-based and environmentally friendly products through fermentation. The new fermentation plant at the BASF site in Ludwigshafen is therefore a further step for the listed company in the planned conversion of its production processes towards sustainability.

Enzyme for improved CO2 utilisation discovered

Not releasing carbon dioxide from industrial processes into the atmosphere, but upgrading it chemically, this approach is intended to make a small contribution to the climate neutrality of the economy. Compared to possible eternal storage facilities for CO2, this is also economically interesting because no disposal costs are incurred and a profit can even be made. Accordingly, intensive research is being conducted on appropriate CO2 utilisation processes.

Measuring the microcosm of biogas plants

Biogas is one of the components that are to replace fossil raw materials in the energy transition. It is produced by microbial communities fermenting biomass. In principle, the processes involved are well understood, but how the microbial communities are composed has only been partially researched so far. An international research team with the participation of the Brandenburg University of Technology Cottbus - Senftenberg (BTU) has taken on this task – and made an important discovery.

Polyamides and fragrances from thistle oil

Can two manufacturing methods be combined into a single and at the same time more sustainable process? This was the question the Linopol project set out to answer four years ago. On the one hand, the team led by project manager Ulrich Schörken from the Technical University of Cologne aimed to replace the previously petroleum-based production of polyamide 12 with a biobased alternative. On the other hand, they were looking to avoid waste products in the production of fragrances and flavorings and turn them into recyclable materials.

Cellulose-based materials as PFAS substitutes

Whether in food packaging, cosmetics, pesticides or outdoor textiles: per- and polyfluorinated alkyl substances – PFAS for short – are contained in many products. These industrially produced chemicals are not only particularly resistant to oil and water, but also to temperatures and chemicals. As diverse as the applications of PFASs are, these substances are equally dangerous when they enter the environment, where they cannot be degraded naturally. PFASs have been detected in more than 70% of groundwater monitoring wells in the EU.

Climate change intensifies heat extremes in the soil

The number of hot days with air temperatures of at least 30 degrees Celsius has been increasing in Germany for years as a result of climate change. This is documented by long-term records of the German Weather Service. In contrast, there is hardly any data on the temperature development in the ground, as the measurements are very complex. In a project coordinated by the Helmholtz Centre for Environmental Research (UFZ), a team of researchers has now examined the development of ground temperature in more detail.
