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.

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.
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.
A new reuse guide seeks to reduce material waste
How to know whether building materials are fit for reuse? A new guide can tell.
Harmful artificial turf can be made into a useful resource
It is difficult to recycle artificial turf and there are no obvious deposit-return systems for these plastics on the market. But researchers are now looking to find a solution to the problem.
What are we going to do with all those used EV batteries?
Very soon, there will be enormous numbers of used EV batteries available, but we have yet to work out how we will be organising the reuse of this massive resource.
Scientists call for cap on production to end plastic pollution
Capping production of new plastics will help cut their release to the environment — and brings other benefits, from boosting the value of plastics to helping tackle climate change.
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.
Are durable goods really that good?
Disposable products are bad. But durable goods account for two-thirds of the global household’s energy footprint.
New technology will identify sources of plastic in the ocean
Plastic trash gets cleaned up along our beaches. But it’s also important to find out where the plastic comes from. A Norwegian app will soon be able to do this.
Using materials efficiently can substantially cut greenhouse gas emissions
Emissions from the production of materials like metals, minerals, woods and plastics more than doubled in 1995 – 2015, accounting for almost one-quarter of all greenhouse gas (GHG) emissions worldwide. Material efficiency needs to play a larger role in climate planning, a new report says.
How much microplastic is there in your laundry basket?
Every time you wash clothes, you are releasing microplastics into the sea, but we know little about the amount and distribution of such material from different types of textile. Research scientists are now working on measuring and capturing microplastics in our laundry.
Entrepreneurs work to help the world reach climate goals
Climate frustration led three former NTNU students to quit their secure and well-paying jobs. Instead, they developed a digital toolbox for the green shift. Now the world is knocking on their door.
Michelin-class composting
Now you can learn how to compost food scraps from a Michelin restaurant. Restaurant Credo folks in Trondheim will be showing off their artistry at the FUTURUM exhibit, part of NTNU’s science festival The Big Challenge.
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.
Nine things to know about microplastics
Picking up a plastic bag from the beach makes a bigger difference than you might imagine.
Making a car workshop into an attractive, energy-efficient urban residence
Combining old and new to achieve reduced energy consumption, a better living environment and architectural success. It’s definitely possible and researchers will show you how.
Food waste recycling not always the best idea
With Norway as a case study, a first-ever effort to quantify the benefits of recycling food waste versus preventing it shows prevention is the best policy. But Norway continues to invest significant funds in biogas facilities for food waste recycling.
Awash in trash at the top of the world
Every year, an estimated 8 million metric tons of plastic waste blows, falls or flows into the world’s oceans. Earlier this autumn, participants in the annual Svalbard Course plucked up 512 kg of the stuff from just one beach in two hours.
Recycling aluminium, one can at a time
Producing pure aluminium from ore accounts for as much as 1 per cent of all greenhouse gas emissions worldwide. Recycling is the best way to reduce that carbon footprint – but manufacturers and recycling companies will have to plan carefully to avoid problems with impurities that accumulate in recycled aluminium over time.
The 80 per cent solution
By recycling used water, we can live with just a couple of buckets of fresh, clean water a day, while the rest of our water will come from recycled sources.
