Resycling of phosphorous at Hias, Norway

Recovering eco-friendly phosphorous from wastewater

A shortage of phosphorous is driving the price of artificial fertilisers through the roof. But a new and eco-friendly wastewater decontamination process has enabled a company in Hamar in Norway to kill two birds with one stone.

Nature’s colours can replace toxic pigments

Dye pigments are often toxic, so researchers around the world have long been looking for effective ways to make non-toxic, recyclable and sustainable colours instead. The answer lies in nanotechnology and nature’s own methods.

ERC grant on food sustainability in China

NTNU researcher Marius Korsnes has been awarded an ERC Starting Grant from the European Research Council (ERC) . He will explore the concept of “sufficiency” when it comes to urban, sustainable food.

Is green growth possible?

Increases in economic growth contribute to one-for-one increases in carbon emissions. Energy system decarbonization and economic productivity gains are the most effective carbon emissions mitigation mechanisms for sustainable economic development.

What is nature worth?

Climate change is not the greatest threat to the diversity of species on Earth. The main problem is that animal and plant habitats are disappearing.

CyborGoats find their way into Norwegian villages

Goats are smart animals. A new technology takes advantage of their intelligence — so they longer need physical fences. More than 2400 Norwegian farmers are already using the technology to herd their animals.

Building with new thinking and old components

An old building at Tullinløkka in Oslo has set a new standard for reuse, consisting of components from other buildings – like concrete floor dividers from a government building. Building stock in Norway accounts for half of society’s total environmental impact. Thinking in new ways and reusing building components offers multiple gains.

Kurobe dam

Retrofitting dams for more renewable energy in the world

Many of the world’s dams are not used for hydropower, but a new study shows they could be easily altered to produce renewable energy. This would be the most sustainable solution for new energy production in the world, says NTNU Professor Tor Haakon Bakken.

Developing the world’s ‘hottest’ heat pump ever

Researchers working with industrial partners have developed the world’s first heat pump producing temperatures of up to 180 degrees celcius. Such record high temperatures will enable one fifth of European industry to reduce its energy consumption by up to 70 percent, and become entirely climate neutral.

Geiranger Fjord World Heritage site

Green quay will provide a green fjord

Big things might be happening soon with cruise traffic in the Geiranger fjord. Smaller vessels and adapted green quay facilities could make for a green fjord and offer a solution for preserving the World Heritage site.

The Longship that could help save the planet

Everyone knows there’s just too much carbon dioxide in the atmosphere — and we’re heating up the planet at an unprecedented pace. In the third episode of NTNU’s new English-language podcast, 63 Degrees North, we’ll hear what Norwegian researchers are doing to help address this problem.

Abandoned cropland should produce biofuels

More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
