Turning waste into gold! BBC Click, the BBC’s flagship technology show, featured this story on how researchers working with Professor Raffaele Mezzenga at ETH Zurich discovered a new way to recover gold and other precious metals from electronic waste. Their highly sustainable method for extracting e-waste is based on a protein fibril sponge which the scientists derive from whey, a food industry byproduct. This story aired around the world on the BBC World News network in 2024. Read more Turning waste into gold.

On 19 March 2019 ETH Zurich presented the Spark Award 2019. The award stands for the most promising invention, which was filed for a patent in 2018. The video features the work of Dr Sreenath Bolisetty and Professor Raffaele Mezzenga from the Department of Health Sciences and Technologies as well as Professor Qingrui Zhang from Yanshan University. The presented technology won the Spark Award 2019 for a new membrane which filters fluoride from drinking water and industrial waste water.

Researchers at ETH Zurich can produce ultra-thin, stable gold foils. The "hybrid gold" is a mixture of the precious metal - and milk protein. Color, consistency and conductivity can be varied: an invention that could be of interest to food, electronics or watchmaker ...
