Sustainable Cities

Knowledge – a distant beacon or the motor that drives the climate transition?

When discussing the transition to a more climate-friendly society, different groups attach different meanings to the concept of knowledge, this has been shown by researchers at Linköping University.

Vallastaden - potential for a smart city

Aspects such as efficient use of resources and social interaction have been included in the planning of Vallastaden. Malin Granath, researcher in information systems, believes that it may eventually be possible to achieve economic sustainability.

Celebrating LiU’s collaboration with China

A sign celebrating the joint research centre in urban sustainable development between LiU and Guangzhou University has been unveiled.  The university managements and mayors from Linköping and Guangzhou attended the ceremony.

Political obstacles to mineral recycling

We are keen to discuss how to bring about a sustainable society, but we seldom discuss how we manage resources. Nils Johansson shows in his doctoral thesis that current policies lead to an increased waste of mineral resources, not the reverse.

Biogas – worth fighting for

“We must tell the world that we could achieve 50% of the EU’s environmental objective for the transport sector using biofuel”. Prof Willy Verstraete issued a call to arms to the participants of the ATBEST biogas conference in Linköping.

Johannesburg looks to biogas

South Africa’s largest city, Johannesburg, wants to reduce its impact on the climate, solve its problems with waste and become an environmentally sensitive city.

Your grocery bag reveals how you drive

If you shop for ecological food, you’re also better prepared to drive an electric hybrid car in the best possible way. But being trained in ecodriving could almost be a disadvantage, as researchers from LiU and VTI show in a study.

The Norrköping Iron and Copper Mine

At the same time as protests against both the current mining policy and mineral legislation are getting louder, Björn Wallsten is prospecting a totally different type of mine in his licentiate – the one underneath central Norrköping.

Welcome to the World of the Urks

We continue to extract metals from the earth’s crust, with the associated risks to the environment, although only half of some of the metals we have already extracted are used. Björn Wallsten found the unused metals in the world of the Urks.

Dig where you stand

There are many good reasons for excavating Sweden’s landfills in search of valuable metals. But it is not happening. In his licentiate degree thesis, Nils Johansson sought an explanation as to why we prefer searching in space to mining our own rubbish tips.

Metals worth billions at local tip

The mines of the future may be closer than we think. A degree project from Linköping University demonstrates that landfill at the Gärstad waste facility in Linköping contains metals worth SEK 3 billion.
