The "heart" of the sorting line is a spectroscopy system developed by the LZH. Based on the reflection spectrum of each material in the visible and infrared range, the system will recognize not only which material it is (cotton, wool, polyester), but also the color.
Used clothes are collected in all major European countries, but what really happens to these textiles? About half are wearable and find their way back into consumer textiles. The other half are either recycled for industrial purposed, for example as insulation material, or they are disposed of. A new European project plans on offering an alternative: Making new clothes from old clothes.
Dutch and German project partners, including the Laser Zentrum Hannover (LZH), are working on a production chain which will turn old clothes into new clothes. The first step is sorting. First wearable clothes are sorted out manually. The rest are automatically sorted according to material and color. The more "pure" in material and color the batches are, the better they can be further processed. The goal of material identification is to reach a 95-99% sorting accuracy at a speed of at least 10 kilograms per minute.
The "heart" of the sorting line is a spectroscopy system developed by the LZH. Based on the reflection spectrum of each material in the visible and infrared range, the system will recognize not only which material it is (cotton, wool, polyester), but also the color. The LZH is responsible for the conception of the identity unit and the software development.
After identification and sorting, the textiles shredded and spun into new threads, which are then woven into new textiles and eventually made into new clothes.
Commercialization of the technology should lead to at least 10 sorting plants in Europe. The 30 month project is supported by the Eco-Innovation Program of the European Commission.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
