Micronutrients intake mapped out
Micronutrients intake mapped out
Micronutrients are minerals and vitamins, such as iodine, iron, or vitamin A. Although ingested in tiny amounts, they are an essential part of our diet .
Buildings rising from the ashes
Buildings rising from the ashes
Urban mining is increasingly being taken seriously by industry because it gives access to materials—such as expensive metals used in electronics—that are buried in waste tips and landfills.
Juggling with multiple risks
Juggling with multiple risks
Multiple disasters can have a cumulative impact leading to great human and financial loss. The awareness of all possible risks is of fundamental importance.
When recycling equates with quality raw materials
When recycling equates with quality raw materials
Twenty five years ago, the German chemist Michael Braungart developed a new approach to recycling, now called "Cradle to Cradle" or "C2C" after the book, Cradle to Cradle: Remaking the Way We Make Things, which he and the American architect William McDonough published in 2002.
Søren Balling Engelsen: how molecules pinpoint deficient diets
Søren Balling Engelsen: how molecules pinpoint deficient diets
Until now, we have had very little understanding of the extent of malnutrition in Europe, especially in populations at risk of poverty. Now, an EU-funded project called CHANCE , aims to address the dietary habits in people with inadequate nutrition.

Keith Tomlins: Controlling waste in tuber crops for a better economy
For 700 million people in Africa and the Far-East, yams and cassava represent important crops for food security and as a source of income.
Marco Borga: Flash floods predictions, subject to models’ limitations
Marco Borga: Flash floods predictions, subject to models’ limitations
Flash floods are very localised weather events. They are mostly triggered by heavy rainfall. Typically, over a period of less than 12 hours. They occur very infrequently at any one place.
Sorting plastic waste: a magnetic game
Sorting plastic waste: a magnetic game
More than one third of the total plastic production in Europe—about 14 million tonnes per year—are polyolefins, also known as polyalkenes.
Greener milk: how to make cow’s nitrogen intake efficient
Greener milk: how to make cow’s nitrogen intake efficient
The amount of nitrogen that is excreted by livestock is directly proportional to the amount it is fed . This is according to Chris Reynolds a researcher in nutritional physiology of ruminants  at  the University of Reading , UK.
Forever recyclable novel plastic thanks to old tyres
Forever recyclable novel plastic thanks to old tyres
Tyres are well suited for recycling. They are easy to collect and do not require any costly sorting process.  However, in Europe, still only about 50% of the tyres are recycled .
Turning tyres into gas for energy and new, valuable materials
Turning tyres into gas for energy and new, valuable materials
Europe's tyre waste production is 3 million tonnes per year. Currently 65% to 70% of used tyres end up in landfills. Not only are they causing environmental damage, but a loss of added value in the form of new products that recycling can generate .

Guy Weets, a telecommunications engineer and consultant for the research centre AMRA (Analysis and Monitoring of Environmental Risk) in Naples, is the scientific coordinator of the CLUVA project, funded by the EU.
Eruption risk perception disconnected from detected threat
Eruption risk perception disconnected from detected threat
Just like earthquakes, volcanic eruptions are extremely difficult to accurately predict. Yet, the eruption of the Santa Ana Volcano in El Salvador was predicted a few days before it happened on 1 st October 2005.
Biomass bonanza as plastics’ raw materials
Biomass bonanza as plastics’ raw materials
Increasingly, many of the plastic products we use every day are no longer based on petroleum raw material . Instead, they are made from biomass such as starch, sugar, corn and other sources that also happen to be food products.

Alessandro Marseglia: Recycling plastic into construction materials
Recycling is now an important part of our economy. Today not only is recycling an important source of material for the production of consumer goods, but it also protects the environment and can save energy.
Plastic waste set in concrete
Plastic waste set in concrete
In Europe more than 12 million tonnes of mixed plastic waste are dumped on landfills every year, according to a report from NUMIX scientists. The recycling of plastic into usable products has proven difficult .
