Replacing toxic chlorine and bromine
Replacing toxic chlorine and bromine
Researchers at ETH Zurich and the University of Mainz developed a new method to replace molecular chlorine and bromine in chemical synthesis with less toxic molecules. The technology helps to make chemical processes safer and more sustainable and to remediate contaminated soils. Chlorine and bromine in their molecular form (as Cl2 and Br2 molecules) are notoriously toxic and corrosive chemicals.

Testing the Blue Diversion Autarky toilet in situ
Testing the Blue Diversion Autarky toilet in situ
For three months, an extended family in South Africa tested the standalone Autarky toilet cubicle. Everyone was very happy with the quiet hideout. "I am really proud of our technology and can see huge potential in it", says Eva Reynaert, who was involved in the project and was one of the advisors during the field testing.

Major discovery helps explain coral bleaching
Major discovery helps explain coral bleaching
An EPFL scientist has made a major breakthrough in the understanding of coral bleaching - a process that causes corals to lose their color and eventually leads to their death. The process is triggered by warmer ocean temperatures, and, according to the study, it begins much earlier than previously thought.

Climate change in antiquity: mass emigration due to water scarcity
Climate change in antiquity: mass emigration due to water scarcity
The absence of monsoon rains at the source of the Nile was the cause of migrations and the demise of entire settlements in the late Roman province of Egypt. This demographic development has been compared with environmental data for the first time by professor of ancient history, Sabine Huebner of the University of Basel - leading to a discovery of climate change and its consequences.

Solar System formation in two steps
Solar System formation in two steps
Why are the planets of the inner Solar System dry and rocky, but the outer ones are not? An international team of researchers with participation of the University of Zurich discovered that a two-step formation process of the planets can explain the chronology and split in volatiles like water and isotope content of the inner and outer Solar System.

TRAPPIST-1's 7 Rocky Planets May Be Made of Similar Stuff
TRAPPIST-1’s 7 Rocky Planets May Be Made of Similar Stuff
The TRAPPIST-1 star is home to the largest batch of roughly Earth-size planets ever found outside our solar system. An international study involving researchers from the Universities of Bern, Geneva and Zurich now shows that the exoplanets have remarkably similar densities, which provides clues about their composition.

Study Identifies European Cities with Highest Mortality Due to Air Pollution
Study Identifies European Cities with Highest Mortality Due to Air Pollution
A health impact study has for the first time estimated the mortality burden attributable to air pollution in more than 1,000 European cities. The study, published in The Lancet Planetary Health, includes a ranking of the European cities with the highest rates of mortality attributable to each of the two air pollutants studied: fine particulate matter (PM2.5) and nitrogen dioxide (NO2).

The stores of the future
The stores of the future
Lidl Switzerland aims to operate its stores even more sustainably and efficiently in the future. Together with Empa, the company now puts this plan into practice. First, the energy consumption and the interaction of various operational systems in existing stores will be analyzed. Then, the Empa researchers will develop an optimized concept for the stores of the future based on the findings of their analysis.

Modelling the energy transition
Modelling the energy transition
An interdisciplinary research team from ETH Zurich is developing the Nexus-e modelling platform in a project supported by the Swiss Federal Office of Energy. The platform facilitates the analysis of how technological, economic and regulatory developments affect the energy system of the future. Switzerland's energy system will undergo a fundamental transformation in the coming years.

Changing resilience of oceans to climate change
Changing resilience of oceans to climate change
Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. An international team of scientists led by ETH Zurich used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago - and found limited expansion of seafloor anoxia (absence of oxygen).

How will we achieve carbon-neutral flight in future?
They emit must be systematically stored underground. This is the most economical of various approaches that ETH researchers have compared in detail. It is politically agreed and necessary for climate protection reasons that our entire economy becomes climate-neutral in the coming decades - and that applies to air travel, too.

Packaging database for fact-checking sustainability promises
Packaging database for fact-checking sustainability promises
Researchers have created a database of over 3,000 primary and secondary packaging items from the range of the retailer Denner as a basis for ensuring more environmentally friendly packaging. The presents are unwrapped, the takeaway is eaten and the latest online order has arrived - and now there is packaging everywhere.

Wastewater treatment plants retain 96 percent of mercury
Wastewater treatment plants retain 96 percent of mercury
Each year, around 130 kilograms of mercury flow into Swiss wastewater treatment plants, which filter out the lion's share from the waste water. This is shown by a survey of almost thirty wastewater treatment plants conducted by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Office for the Environment (FOEN).
