Researchers at Chalmers present a new way to recycle metals from electric car batteries. The method makes it possible to recover 100 percent aluminum and 98 percent lithium from already used electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process, as the researchers use oxalic acid – an acid that also occurs in the plant kingdom, according to a press release.

– So far, no one has managed to find exactly the right conditions to separate this much lithium with oxalic acid – and also remove all the aluminum at the same time. Since all batteries contain aluminum, we need to be able to remove it without losing the other metals, says Léa Rouquette, PhD student at the Department of Chemistry and kSee more

An artwork in the form of an island will show the effects of climate change.

Behind the island, Future island, are the Dutch architectural firm Ooze and the artist Marjetica Potrč.

– The artwork is an investigation of how nature adapts to a new climate, says Eva Pfannes from Ooze the Arkitekten newspaper.

The island has been built with rocks and stone at Campus Albano at Stockholm University and consists of two parts to simulate an expected temperature increase of five degrees in 100 years. Through a solar cell system in the stones, one half is always five degrees warmer than its surroundings. The same kind of plants are planted in both zones so that you can follow the development of the plants and how they adapt to the climate. Sensors among the stones record data about environmental factors.

The architects collaborate with climate scientists at the Stockholm resilience center.

Urban gardens, more green areas, increased environments for walking and cycling. Dozens of European cities can become carbon dioxide neutral if nature is allowed to take up more space in the urban environment. This is shown by a study published in Naturewhere, among other things, researchers from Royal Institute of Technology attended. The result shows how cities can create and coordinate a wide range of green solutions such as parks, street planning and roof gardens to both capture and reduce carbon dioxide emissions.

The study has been carried out by researchers from Sweden, the USA and China and recommends the most effective methods for natural carbon sequestration in 54 cities in the EU.

The study shows how a mix of green solutions together with other climate measures can enable cities to reach net zero carbon dioxide − and also reduce emissions withSee more

Agriculture’s impact on the climate is said to be one of the big issues at the UN climate conference Cop 28 in Dubai in December.

Former employees of the UN Department of Agriculture have stated that they were previously silenced.

Their information about agriculture’s impact on the climate must have been censored, undermined and sabotaged.

This is stated by The Guardian.

Above all, it is about figures about agriculture’s emissions of methane gas.

But now there will be a change in that.

Agriculture’s impact on the climate is said to be one of the most important issues at the Cop 28 climate conference in Dubai.
