In the chemical industry, carbide is an important base material for fertilisers and in the production of raw iron. Until now, the synthesis of carbide has principally been based on the use of coal and coke, which have become increasingly more expensive as a result of the high worldwide demand for energy.
However, the carbon required for producing carbide can also be obtained from plastic waste. The BINE Projektinfo brochure “Producing carbide using plastic waste” (08/2011) presents a new process that enables the material- and energy-based use of residues from the processing industry and is now entering regular operation.
The manufacture of one tonne of carbide requires between 3,200 and 3,500 kWh of electricity, whereby one tonne of lime and 0.6 tonnes of coke and coal are used as the raw materials. In order to partly replace them, the new synthesis process also enables the use of sorted, pre-selected and shredded waste from the plastic processing industry. The test production has confirmed the excellent product quality of the carbide produced and the emission values conform to the statutory required limit values. Heavy metals and chlorine compounds are filtered out. Because they occur in very concentrated form in the filter dust, this produces very little waste that can be relatively cheaply disposed of in comparison with alternative recycling processes.
The new process has been developed by a southern German chemical company. In future, it plans to produce more than 10% of the carbon required for the carbide synthesis using plastic waste. A market survey that the company conducted in advance has shown that sufficient amounts of waste are already produced from plastic processing industries in the surrounding region.Press contact

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...
