Fatty fish like salmon and sardines are important natural suppliers of these substances to the human diet. But an increasing share of fish comes from fish farms; and much of
Concrete degradation is one of the most costly problems of our time. Concrete will always crack, although less so if well-designed and well-constructed. Cracks will allow water and air to enter into the structure and eventually reach the steel reinforcement. When this erodes, it swells, causing more cracks. Concrete degradation of our infrastructure now requires
Cement production by itself is responsible for a stunning 5% of total global CO2 emissions. As global construction activities still gear up, we urgently need more sustainable concrete, no longer based on Portland cement, the basis of the construction industry for the past 200 years.

A relatively recent interest in hemp as a building material responds to a global trend that encourages the development of bio-based products and the reduction of carbon emissions.

Problems arise only when genetically modified food is the issue. Or won’t they? This is the second of two columns on genetic

In a first article, we proposed that plastic waste should no longer exist in ten to fifteen years from now. This ambitious goal needs to be tackled from two sides: plastics design on the input side, and dedicated processing on the output side. In both processes, chemists play a major role. And industry should show
