"Energising a Sustainable Industry" is the guiding theme of Hannover Messe 2024. This year, the world's largest industrial trade fair is focussing on innovations for the sustainable production and energy supply of the future. Solutions for CO2-neutral production, AI-based technologies and green hydrogen production are on display.
Algae are among the marine plants that researchers have long recognised as having great potential for the bioeconomy and which are already being used in a variety of ways. Other salt-tolerant plants such as the European seaweed (Salicornia europaea), on the other hand, have received little attention - but also have many qualities. This is the conclusion reached by a European research team that spent four years investigating the potential of these so-called halophytes.
There are around 120 coffee varieties worldwide. However, the Arabica variety is at the forefront of coffee production with 70%. However, climate change is increasingly causing yield losses, as the plant is extremely sensitive. It tolerates heat and drought poorly and is therefore more susceptible to disease. What's more, experts believe that suitable areas for coffee cultivation will continue to shrink as a result of climate change. This would also affect Brazil, which is one of the world's leading coffee producers.
Industrial biotechnology utilises microorganisms or individual biomolecules such as enzymes in bioprocesses as the basis for the industrial production of chemicals, biopharmaceuticals or food additives. The key players are cells as living factories that can produce a desired product in large quantities in closed bioreactors. Developing bioprocesses in such a way that the biotechnological production of a product is optimised is very time-consuming and complex.
"Energising a Sustainable Industry" is the guiding theme of this year's Hannover Messe, which opens its doors to visitors next week. From 22 to 26 April, more than 4,000 companies from the mechanical engineering, electrical and digital industries as well as the energy sector will be presenting their solutions for a sustainable industry of tomorrow - including global tech companies and research institutions as well as more than 300 start-ups.
Plants mediate their interactions with the environment via chemical signals. One example of this is the alkaloid gramine, which is produced by barley, one of the world's most widely cultivated cereals. Gramine provides protection against herbivorous insects and grazing animals and inhibits the growth of other plants. The toxin is particularly present in the green parts of the plant, such as leaves and stalks, but hardly ever in the grains, which can be safely used for food production.
In the TRABBI junior research group, which is funded by the Federal Ministry of Education and Research (BMBF), economic geographers Lukas Kriesch and Sebastian Losacker from the University of Giessen have obtained regionalised data on bioeconomy companies in Germany. They report on their analysis in the scientific journal "REGION - the Journal of ERSA".
Soil is home to countless microorganisms such as bacteria, fungi and algae. These invisible microorganisms form communities in a wide variety of ways, ensuring a smooth nutrient cycle and thus fertile soil and plant growth. How these microorganisms work together and which factors promote or inhibit growth has been the subject of research at Friedrich Schiller University Jena for many years.
According to Deutsche Umwelthilfe, the construction sector is responsible for 40 % of total raw material consumption and 12 % of greenhouse gas emissions in Germany. The joint project DACCUS-Pre pursued a promising approach to reducing greenhouse gas emissions in the construction sector.
Maize is a versatile crop. In the food sector, its cobs are on the grill and oil can be pressed from the kernels. A large proportion of the harvest is also used as animal feed and the pharmaceutical industry uses maize dextrin, a carbohydrate obtained from the plant, as a carrier and binding agent.
