Cities offer an array of opportunties for a sustainable future

Today, half of the world's population lives in urban areas. This is giving rise to major challenges in terms of securing a sustainable future - a topic that will be explored during the World Cities Day on 31 October. Here is an overview of EPFL research carried out in this field.

3D printed reactor core makes solar fuel production more efficient

Using a new 3D printing technique, researchers at ETH Zurich have developed special ceramic structures for a solar reactor. Initial experimental testing show that these structures can boost the production yield of solar fuels.

This bottle makes sparkling water on the go

Sparkling water on the go at the touch of a button and entirely plastic-free. The new water bottle by ETH spin-off bottleplus makes this possible.

Battery-go-round

Empa and Kyburz Switzerland AG are looking for ways to recycle end-of-life lithium-ion batteries in an efficient and resource-saving way. A specially developed experimental facility breaks down the old batteries into their components so that materials can be recovered as clean as possible.

Generating clean electricity with chicken feathers

Turning unused waste from food production into clean energy: Researchers at ETH Zurich and Nanyang Technological University Singapore are using chicken feathers to make fuel cells more cost-effective and sustainable.

ETH Zurich researchers study one of the world’s darkest rivers

They set out to study the Congo Basin’s carbon cycle and in the process have become aware of one of the world’s darkest blackwater rivers: the Ruki. In the first study on this major jungle river, an international research team led by ETH Zurich explains how this blackness comes about and what it says about the river system’s carbon balance.
