The plant Bizkaiko Txin-Txor Berziklategia (BTB), located in La Orkonera, Ortuella (Bizkaia, Basque Country) is the first plant of the Basque Autonomous Region dedicated to the assessment of waste derived from construction and demolition. Its set up, after an investment of 2,6 million euros, is going to prolong the average life of dumping sites.
The construction company Pavisa and the public corporation Garbiker, dependent on the Regional Council of Bizkaia, have designed the plant BTB for the treatment of construction waste, constituted basically by concrete, and domestic waste, sent to the garbigunes (centre of waste recovery).
The plant applies an adequate environmental treatment for this kind of waste and its subsequent re-utilisation. To do that, waste is first ground in a mill. The clean concrete is sieved and domestic waste goes to manual separation of wood, plastic and iron material. During the grinding and sieving process, iron remains are eliminated and fractions of different granulation are obtained. This material, once it is homologated, is ready for its re-utilisation. BTB has obtained the authorisation of the Basque Government to give added value to this kind of waste.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
