Manure coating improves biochar's fertiliser qualities

Biochar is a carbon-rich, charcoal-like substance made from oxygen-deprived plants or other organic material. It can store large amounts of carbon and when applied as a fertilizer it slowly releases nutrients into the ground. However, the exact mechanisms how biochar stores nutrients and promotes plant growth have not been identified yet, which also severely limits its commercial potential. An international team of researchers, led by the University of Tübingen in Germany, deciphered the storage and release mechanisms of biochar.

Fewer ammonia emissions could save lives

Air pollution is most commonly associated with traffic and car emissions. However, there are a number of other sources for pollution, such as agricultural emissions due to fertiliser use. According to researchers at the Max Planck Institute for Chemistry in Mainz, Germany, reducing ammonia (NH3) emissions by 50% could avoid the deaths of more than 250,000 people each year that are caused by air pollution worldwide.

Microbes isolate precious metals in pilot plant

An international research team involving scientists from Brain AG has succeeded in extracting nearly the entire copper content from local shale deposits by applying a novel bio-leaching process. In the early extraction phase, microbes that are used for the bio-leaching process first convert insoluble ore minerals into water-soluble salts. Downstream, a bio-chemical precipitation process then recovers up to 97% of the dissolved copper.

Frankfurt: opening of new Green Finance Cluster

Innovations that advance a sustainable economy are not only difficult in their technical realisation, but also require financial support. In order to bring them to the market, oftentimes large investments become necessary. The aim of the new Green Finance Cluster in Frankfurt, which was opened recently, will be to connect innovations and funding possibilities. In the middle of November the Secretary of State for Trade and Industry in Hessen, Tarek Al-Wazir said: “A focus on sustainability is indispensable for the financial sector.

Intestinal bacteria produce mussel adhesive

Mussels produce and use one of the strongest biobased adhesives known to date, because they live in the tidal and shelf areas of the oceans and must therefore withstand strong currents and salt water. Exactly such a strong and biobased super glue would also be very useful in regenerative medicine: biocompatible adhesives could be used to treat superficial wounds, and could replace plates and screws, which are commonly used to treat bone fractures.
