Circular economy: digitalisation could close loops

Circular or closed-loop economy is the holy grail of any sustainable economy. The idea is that no materials are being wasted and lost during production, and instead everything can and will be reused and recycled. However, although Germany has one of the most advanced waste management systems in the world, only about 14% of the raw materials used in the German industry are derived from recycling processes.

Protein summer drink made of lupins

Cool, refreshing drinks are always welcome during the summer time. But many customers shy away from high sugar contents and too many chemical ingredients in commercially available sports drinks. Therefore, researchers at the Fraunhofer Institute for Process Engineering and Packaging IVV in Freising developed a novel, protein-rich summer drink made from sweet lupins. The production of this new drink should be feasible for any brewery. The technique was developed in cooperation with the Technical University Munich as well as partners from industry.

Gas bubbles trigger tree drought mortality

Trees are extremely important for a healthy ecosystem and a stable climate. Plants take up about half of the CO2 emissions that humans put in the atmosphere, and a huge part of that is accomplished by trees. CO2 emissions are one of the major driving forces behind global warming. Thus, it is paramount that as many trees as possible stay healthy and alive in order to function as CO2 emission sponges and slow down further climate changes.

Dodder does more than feed off plants

Few organisms can survive on their own, many live in symbiosis with others, some of which are parasitic. Dodder, a parasitic vine of the genus Cuscuta, grows rapidly, entwining and parasitizing its host plants by inserting haustoria (a special organ that only parasitic plants have that functions analogue to roots) into the host plants’ stems. The dodder vines often connect different host plants together and form a network.

More is not always better

The health of an ecosystem is founded on the complex interplay between its numerous inhabitants over a prolonged period of time. Therefore, assessing the state of an ecosystem solely on the basis of short-term changes in the number of different species it contains can lead to false conclusions.
