Intelligent packaging with sensors that monitor goods, such as vegetables, on long transport routes is a trend for the future. Yet printed and disposable electronics also cause problems: Metals in printing inks are expensive – and disposing of them in an environmentally sound manner is costly and exacerbates the problem of electronic waste. A new solution from Empa researchers aims to remedy this.

Buildings, roads, railways, supply and disposal networks and much more: The entire Swiss built environment is as complex as its challenges for the future – due to climate change, natural hazards, population growth and other factors. Where to start? With which priorities? An expert group has launched an initiative for an overall view – and thus is giving new impetus for research and practice.

Noise barriers or improved wheel systems and brakes that are less noisy are not the only ways to reduce railway noise for close-by residents. An inconspicuous component under the tracks is a source of hope for a research team including Empa scientists.

Indoor air quality has an influence on how many corona virus infections occur there. This has now been shown for the first time in a pilot project involving Empa researchers in 150 primary school classrooms in Graubünden. The analysis also showed that the air quality in many classrooms is poor. The study concluded that regular ventilation of classrooms is therefore very important, even in winter months.

The World Climate Conference in Glasgow has just ended, and the question is whether the goal of maximum global heating of 1.5°C can still be achieved. In a model calculation, Empa researchers show how the energy transition could lead to the lowest possible cumulative emissions: Instead of slowly cutting back emissions, we should quickly push ahead with the conversion to solar energy and use fossil power plants at full capacity for one last time to do so.
