Recycling snuff boxes to make new products

Don’t tell me that you haven’t noticed them. Empty snuff boxes littered all over our streets and parks. But instead of being just rubbish, they can now be recycled to make new products.

Just one degree can change a species

Even seemingly small changes in the climate can change the number of animals and plants in an area and how species behave, new research shows. Natural history collections provide valuable insights.

Eavesdropping on the Earth itself

This summer, a coalition of researchers led by the Norwegian University of Science and Technology reported the first-ever use of a fibre-optic cable network to eavesdrop on whales in the Arctic. Now they suggest these networks be used to establish a low-cost global ocean-earth observatory.

In search of a smarter grid

The Norwegian government is committed to reducing greenhouse gas emissions by 55 per cent by 2030. This will involve dramatic changes to the electricity grid system.

NOTES

Easier to recycle agricultural plastics

Researchers are currently working to improve the recycling system for agricultural plastics. Their aim is that more plastic shall be recovered and recycling made simpler and more effective.

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.

More efficient ocean mapping and monitoring

Australia has a seafloor monitoring program where they can precisely surveil the changes in the environment. NTNU has attracted one of the key researchers from this project. Oscar Pizarro’s research goal is to find tools to facilitate continuous observation with less resources.

Miniscule signals can prevent major accidents

By listening to electric machines’ magnetic fields, faults can be detected that could prevent potential disasters with electric vehicles. The new method could also save power producers large sums of money.
