  • HYBRIT will de-carbonize the steel industry

    When the UN Climate Summit gathered the world's leaders in New York last fall, two Swedes were the talk of the town: Greta and "HYBRIT" - an initiative by SSAB, Vattenfall and LKAB that will make steel production fossil-free and substantially reduce CO2 emissions in Sweden. KTH plays an important role in what is called a revolution in steelmaking.

  • Recovered electronics reduce carbon footprint

    Waste from electrical and electronic equipment (WEEE) is estimated to grow to about 12 million tons by 2020 in EU, which makes it the fastest growing waste stream. By mixing recovered WEEE in metal production, the carbon footprint decrease considerably. WEEE also contains more than 30 % of plastics, which can be a useful source of chemical feedstock and energy.

  • Sustainable refrigerators thanks to magnetic materials

    Magnetic heat-pumps offer a low-energy demand and environmentally friendly alternative for the classical refrigeration industry. The process is called Magnetocaloric refrigeration and the Department of Materials Science and Engineering is working on developing materials based on cheap and less scarce metals like iron, manganese, arsenic, phosphorus and silicon.

  • High energy X-rays reveal the resistance of steel to embrittlement

    The high energy X-rays at the Swedish Material Science beamline make it possible to see what’s happening within steels, in real-time, also in environments that mimic how the steel is used. This enabled researchers from KTH and Sandvik Materials Technology to find out why steels from Sandvik are more resistant to hydrogen embrittlement than other steels.

  • Elastic "memory" metal achieved without relying on heat

    Elastic metal alloys are able to “memorize” their previous form after being subjected to temperature change. Now a new alloy has been developed which becomes elastic at room temperature.
