  • Climate-neutral wastewater treatment plants thanks to patented real-time analytics - 08/11/2023 White technical cabinet with four hoses placed at the edge of a wastewater treatment plant.

    Using AI to reduce greenhouse gases in wastewater companies

    The wastewater industry is responsible for global greenhouse gas emissions equivalent to those of global aviation. The start-up Variolytics has found a way to significantly reduce greenhouse gases in wastewater treatment plants using real-time analytics. The patented sensor technology and AI-supported process optimisation offer multiple benefits: in addition to reducing nitrous oxide, the system helps to reduce energy costs and resources.

    Light conveyed by the signal transmitting molecule sucrose controls growth of plant roots

    Team of Freiburg researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark – they receive the products of photosynthesis, in particular sucrose, i.e. sugar, via the central transportation pathways of phloem.

    How plants use sugar to produce roots

    Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. An international team of plant biologists has demonstrated that it is based on the activity of a certain factor, the target of rapamycin (TOR) protein.

    Agriculture 5.0: fighting the climate crisis with agrophotovoltaics and biochar

    Climate protection, agriculture and biodiversity are closely intertwined. Agriculture 5.0 provides positive guidance, as the Offenburg University of Applied Sciences has demonstrated: agrophotovoltaics (or agrivoltaics), which is currently in vogue in Germany, can be used to generate solar power on high-yield fields. Biomass strips and biochar remove CO2 from the atmosphere. All this improves soil quality and promotes biodiversity.

    Working towards a hydrogen economy with a wastewater biorefinery: the SmartBioH2-BW project

    A biorefinery that uses industrial wastewater and residual material streams is being built in Rheinfelden (Baden). It will have two interlinking bioreactors and will synthesize biohydrogen as well as organic basic materials such as carotenoids and proteins. SmartBioH2-BW is a pilot project run by the Urban and Industrial Biorefineries initiative and funded by the Baden-Württemberg Ministry of the Environment, Climate Protection and Energy Sector.

    Reducing carbon dioxide emissions and the capture and utilization of CO2 are important steps towards achieving a climate-neutral and sustainable economy. Accordingly, as part of the ValBio-Urban research project, an interdisciplinary team from the University of Stuttgart is developing bioeconomic approaches to solutions that will be implemented with companies from Baden-Württemberg.

    A tasty dish for chickens: Researchers from the University of Hohenheim in Stuttgart were able to feed the animals the first 50 kilos of protein extract that were obtained from pasture. Yet the plants found in fields and meadows offer much more than a new source of protein for pigs and poultry: They could also constitute an alternative to soy for human nutrition. They also form a basis for organic-based plastics and paper, energy, and…

    Algae as microscopic biorefineries

    Fossil raw materials are limited and not available and extractable everywhere in the world – as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources will therefore play an increasingly important role in the future: as energy sources, but ideally also as suppliers of building blocks for more environmentally compatible chemicals and materials.

    Carbon farming - climate protection on agricultural land?

    Agriculture plays a key role in helping to achieve European climate targets. Central to this goal are measures that are collectively referred to as carbon farming and are often used for offsetting greenhouse gas emissions. Two Baden-Württemberg companies - CarboCert and Carbonfuture - are active in addressing the challenges and potentials of carbon farming.

    Peatlands as CO2 reservoirs: simultaneous renaturation and use

    Peatlands store more carbon dioxide than any other ecosystem in the world. However, when drained, they become a climate-damaging source of CO2. The management of wet peatlands reveals exciting solutions, with market potential in the areas of local heating, insulation, packaging and even peat substitution.

    Peatlands as a climate protection factor - binding CO2 instead of releasing it

    All intact peatlands on our planet store twice the amount of CO2 as all forests. Peatlands are indispensable for preventing and mitigating the effects of climate change. The only problem is that 95 percent of Germany's peatlands have been drained, and thus release around 7 percent of Germany’s total CO2 emissions into the atmosphere. Rewetting is therefore imperative for the climate, the environment and biodiversity – and economically…

    Bacteria produce bioplastics: resource-saving and very environmentally friendly

    Using living cells as mini-factories to produce plastic from nothing more than water, sunlight and carbon dioxide; plastic that is also 100 percent degradable – it sounds far-fetched but it actually works: researchers at the University of Tübingen have genetically engineered cyanobacteria so that they fill their cells to the brim with polyhydroxybutyrate. The researchers are now turning the idea into reality with the development of pilot plants.
