The SINTEF Group, in co-operation with the re-cycling company Tomra now goes beyond cash deposits for bottles and cans to recycling plastic, glass and metal. Newly developed, patented technology makes it possible to sort different types of plastic, different colours of glass as well as metal – easily, effectively and inexpensively. A new, inexpensive gas-detector that contributes to a better indoor climate, is another area of use.
Although many things can be recycled or reused, it is a major challenge to sort this rubbish. It is expensive and complicated, because it’s not easy to see which plastic type makes up the bottle, cup or can. If the plastic is to be reused, different types cannot be mixed. It requires “clean merchandise”!
But a little, gold-covered plastic chip – as easy to produce as a CD – can manage this work. The surface is holographic, reflecting light in a carefully programmed way. With the help of new software that interprets the spectrum of light reflected from or passing through different materials, each material’s “fingerprint” is read very accurately – whether solid material or gas.

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
