New solar panels from solar panel waste 

Solar energy is good news for planet Earth – but solar panels are not as climate-friendly as they should be. Researcher Martin Bellmann is using what he calls the ‘black gold’ waste materials from solar panel manufacture to make new panels.

Innovative recovery of valuable raw materials from ‘red mud’

Waste slags from the metallurgy industries often contain valuable materials, but in very small concentrations. This means that large areas of valuable land are used to accommodate reservoirs filled with what is sometimes toxic waste. We now want to use hydrogen to convert this waste into a resource.

‘Bio-batteries’ enable us to store solar and wind energy

Up until now it has been a challenge to store the energy we generate when the sun is shining and the wind is blowing. But researchers at a laboratory in Trondheim in Norway have succeeded in doing just this – and entirely without any form of advanced battery technology.

Why there is still hope for our planet

Is it too late to save our planet? Professor Jianguo Liu is the newest winner of The Gunnerus Award in Sustainability Science. He offers us some hope.

Is it really selfish to complain about electricity prices?

Norwegians are not necessarily being selfish by wanting to go back to the good old days of cheap electricity. Nor do people think it is acceptable to use the situation for some to enrich themselves at the expense of others, says the researcher.

Thousands of environmental bombs under Norwegian homes

Heating with oil in homes and commercial buildings is now banned in Norway. The storage tanks are supposed to be removed from buildings, but many people choose not to get rid of these environmental time bombs.

Could this dry battery system be Elon Musk’s next big thing?

The idea behind batteries is to make the planet greener, but they all start their lives as energy-demanding environmental liabilities. Research scientists at SINTEF have succeeded in making batteries cheaper and simpler using a process that requires much less energy consumption.

First ones out to buy and sell neighbourhood electricity

Many buildings with solar cells produce more electricity than they consume themselves, but current legislation prevents surplus power from being sold to neighbouring consumers. A pilot project in Trondheim will be the first in the world to test a system that makes this possible.

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.
