The case for low methane-emitting cattle
The case for low methane-emitting cattle You may think that climate change is being caused by burning oil, coal and gas. But not so fast! The emission of methane from cattle is a surprisingly important factor .
Air quality models: new health prevention tools
Air quality models: new health prevention tools We are all exposed to polluted air. Among main air pollutants are nitrogen oxides —the so-called ‘NOx ‘— and ozone , which cause irritation of respiratory tract and eyes, favouring cough, lung infections in children and asthma.
Laurence Rouïl - policymakers now trust air quality models
Laurence Rouïl - policymakers now trust air quality models Air quality is a public health issue. As recently as last October, the World Health Organisation classified global outdoor air pollution as ‘ carcinogenic to humans .
Forecasting air pollution
Forecasting air pollution Air quality is not a local problem. Like clouds moving through the sky, pollution is transported from one location to another by wind patterns in the atmosphere .
David Kay: cleaning up Europe’s bathing waters
David Kay: cleaning up Europe’s bathing waters Europe’s bathing water has come a long way in the last few decades. Especially since the EU Bathing Water Directive in 1976, countries have worked to eliminate sewage contamination in the waters we swim or paddle in.
Edward Soméus – when animal waste provides greener fertilisers
Edward Soméus – when animal waste provides greener fertilisers The Swedish environmental engineer Edward Soméus invented in the early ’80s a CO 2 free technology, abiding by the 3R principles: Recycle-Reduce-Reuse, to manufacture a natural fertiliser called biochar .
Bitumen roofing can be recycled… but isn’t
Bitumen roofing can be recycled… but isn’t Bitumen, the sticky, gooey black stuff you sometimes see oozing out of hot road surfaces, is a valuable binding agent. Not only in road building. But also in construction and in the production of roofing materials.
To be or not to be green
To be or not to be green What happens to research findings once the researchers have gone away? A web site run from the University of Stuttgart in Germany offers scientists an opportunity to bring their own data from completed research project on environmental and health risks and contribute to an Integrated Environmental Health Impact Assessment System, dubbed IEHIAS .
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.
Closing the water cycle
Closing the water cycle Clean freshwater faces various threats such as increasing demand by population growth, pollution and changes in the hydrological cycle due to climate change.
Screening eco-innovation level
Screening eco-innovation level Going green is one of the fastest growing trends, particularly in industry. But smaller size companies are often left wondering how best to become more environmentally friendly .
Christoph Heinze: peering through the global carbon cycle
Christoph Heinze: peering through the global carbon cycle Currently, the ocean takes up about 25% of the carbon dioxide emitted by human activities. But this uptake rate is governed by a number of factors, including global warming, which are not yet entirely understood.
Antonio Bombelli: Africa’s carbon cycle under scrutiny
Antonio Bombelli: Africa’s carbon cycle under scrutiny The results of climate change are going to have more impact in Africa than other regions due both to ecological and socio-economic factors. However, little is known about the role of Africa with regard to greenhouse gases emissions.
Cleaning up behind the fashion industry
Cleaning up behind the fashion industry The European fashion industry is a huge consumer of fresh water. Estimates point to 600 million cubic meter of fresh water being consumed yearly in Europe by the textile and clothing industry ; not a negligible amount.
More Crops per Drop!
More Crops per Drop! A solution is much needed to fight droughts and preserve crops. Researchers have now developed a device capable of checking the humidity in the soil, and releasing irrigation water as needed – just enough without wasting it .
Troubled Danube’s waters, not up to standards yet
Troubled Danube’s waters, not up to standards yet There are 19 countries in the catchment area of Danube River. The extensive use of water resources in that area has not been without consequences on its water quality. Let alone on the riverside’s biodiversity and environment.
Saving the blue waters pouring into the Black Sea
Saving the blue waters pouring into the Black Sea The Black Sea is known for its severe environmental degradation. Some signs of recovery have been observed in the last years, albeit on a small scale . Scientists believe that it is still possible to limit the negative environmental impact.
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.
Can enamels’ environmental impact truly be reduced?
Can enamels’ environmental impact truly be reduced? Enamel cookware is ubiquitous. The trouble is that enamels —like other vitreous substances, or frits, used in making porcelain or ceramic glazes— are produced through a process generating highly toxic chemicals .
User awareness key to effective energy monitoring
User awareness key to effective energy monitoring Energy efficiency has become a key objective in the current context of increasing energy demand, decreasing resources and global warming. Key to efficient energy savings, however, are users' awareness and behaviour.
