How stores can throw out less food
Grocery stores throw out 75 000 tons of food annually. By adding date tagging to the barcode, food waste could be dramatically reduced, say two NTNU students.

Reindeer adapt to climate change by eating seaweed
The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.
Carbon capture is cheaper than ever
According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.
Finding ways to use less salt on snowy roads
It’s springtime in much of the northern hemisphere, although spring snowstorms are still possible. When that happens, salt trucks and ploughs help make roads safe. But road salt can be bad for the environment, and can rust cars, bicycles and other metal. New research shows that salt use can be safely — and substantially — cut in certain circumstances.
EU consumption results in high carbon emissions from tropical deforestation
A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies shed light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.
Gunnerus Award goes to expert on biodiversity
Ecology professor Sandra Myrna Díaz is the winner of the 2019 Gunnerus Award in Sustainability Science.
This solar panel is the first in the world to store both electricity and heat
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
Short-term hydro operation planning could bring in billions
What is the best timing for the various hydroelectric plants to produce power? NTNU and SINTEF have developed an efficient and profitable simulation tool to make the most of hydropower generation.
Could Trondheim be Norway’s new seabed mining capital?
Stavanger is Norway’s oil capital. Trondheim could become the country’s capital for seabed mining. It will be an important contribution to the UN’s climate goals.
Snake robot ready to go on watch in the deep seas
A snake robot will soon be relieving divers and mini-subs in the North Sea. But first researchers have to test its mettle in the Trondheim Fjord.
Danish-Norwegian Cooperation on Offshore Wind Expanded
Better and cheaper offshore wind farms are the goal for a new cooperative effort on renewable energy.
When the Chinese giant awakes
When China sets its sights on a goal, the country can change at a blindingly rapid pace. Now the country is focused on innovation and technological innovations, with renewable energy at the forefront.
Ocean acidification stimulates mass development of toxic algae
If carbon dioxide concentrations in the atmosphere and in the ocean continue to rise, this could fuel the mass development of toxic algae, with far-reaching consequences for the pelagic food web, an international team of researchers has found.
When the hum of insects disappears
Several countries are warning of massive insect deaths. Right now we don’t know how matters stand in Norway. But that’s about to change.
Santa Claus take note: winter is coming, but get yourself a raincoat
Climate change in the Arctic means more winter rain, and consequently more rain falling on snow. The result can be a buildup of ice under the snow, which can wreak havoc with arctic ecosystems.
Making it easier to capture CO2 in the cement industry
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
Six billion NOK for new Ocean Space Laboratories
Three new fjord laboratories, one in Trondheim, one in Hitra/Frøya and one in Ålesund, along with two test basins in Trondheim are planned as part of the project.
“Urban mining” technology nominated for research prize
New technology will be used to recycle rare and valuable metals from waste materials such as electronic scrap and foundry slag. The process is profitable and may help to reduce environmentally harmful mining operations. The method is now in the final for the EU-research prize “Best early stage innovation 2018.”
Norwegian trees can power our jets
As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country’s forest residues. This alone could cut greenhouse gas emissions from Norway’s aviation sector by 17 per cent.
Spending our carbon budgets wisely
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
What does sheep grazing do to the mountains?
Livestock grazing affects the landscape. What effects does it have on the vegetation?
Ecolabels alone don’t work
NTNU researchers wanted to see if labelling products and putting up signs in stores would encourage more consumers to buy sustainable seafood. The results showed that customers bought significantly more seafood generally – including options that were not sustainably harvested.
Electric cars are a hazard for blind people
Electric cars are good for the environment – but not for people who cannot see. They have problems detecting the silent vehicles. However, Norwegian research scientists are working on a solution.
Entrepreneurs aim to end ghostfishing
A small device, developed in Norway, will now be used in the battle against environmentally-unfriendly ghost fishing caused by lost or forgotten fishing gear.
