The study was carried out at the newly launched Center for Sustainable Communications at the Royal Institute of Technology, in collaboration with STFI-Packforsk. It investigated the environmental impact of various ways of reading the daily paper. The findings show that a half hour of reading an Internet newspaper per day has about the same environmental effect as reading a paper newspaper.
"If you read the newspaper for 30 minutes each day on e-paper instead, the load will be lower. Reading it on the Web for 10 minutes yields the same load. The alternatives are not entirely comparableyou obviously get more out of reading for 30 minutes than 10. Of course, reading the paper version is not really comparable to reading electronically," says Åsa Moberg, one of the researchers behind the report.
e-paper has a resolution of 170 dots per inch, which is twice as high as what we are used to from computer screens, offering sharpness close to that of a newspaper. It can also be read in bright light and doesn't flutter the way a computer screen does. Some prototypes are thin and can even be rolled up, just like a traditional newspaper.
Using so-called simplified live-cycle assessment (LCA), the researchers studied the resource use and environmental impact from the entire life cycle of the various alternatives: editorial work, paper production and printing, production of computers and e-paper respectively, reading the newspaper, and waste management of the paper and electronics.
The greatest burden on the environment for the paper version is the production of the paper. For the Web-based version what harms the environment is primarily the use of energy in order to read the paper on the Net, while with the e-paper version it's the production of the terminal.
"The environmental load and differences in environmental performance for the products change depending on whether you place it in a Swedish or a European perspective, primarily owing to different means of generating electricity. The products' contribution to different sorts of environmental impact differs as well, but in general the paper and Internet newspapers with a longer reading time burden the environment more than e-paper and the Internet version with a shorter reading time," says Åsa Moberg.
Other factors that affect the environmental load are how many people read a specific copy of a newspaper and the length of life for a computer, a screen, and e-paper. Whether the equipment is used by one or several people and whether it is used for purposes other than newspaper reading are also factors to be considered.
e-paper is still under development, and more detailed studies of production, substances used, and waste management need to be done to steer this product development in the right direction, according to Åsa Moberg.
"The study shows that e-paper has potential from an environmental point of view if readers and newspaper companies are interested. However, we still don't know how it will be dealt with as waste, and the data for the chemicals involved are uncertain," she adds.
The study "Screening environmental life cycle assessment of printed, Web-based, and tablet e-paper newspapers" was carried out by Åsa Moberg, Section for Strategic Environmental Analysis at the Royal Institute of Technology and STFI-Packforsk, Martin Johansson, STFI-Packforsk, Göran Finneveden, Section for Strategic Environmental Analysis at the Royal Institute of Technology, and Alex Jonsson, Section for Media Technology and Graphic Production at the Royal Institute of Technology.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
