Converting waste plastics into gas

07.06.2016

Until now, plastics such as PVC have created problems during waste treatment. Although they have a high calorific value, their combustion produces harmful compounds that can escape into the environment. The BINE-Projektinfo brochure "Generating syngas from plastic wastes" (05/2016) presents a new gasification process for this waste fraction. In this process, waste plastics, carbon-containing sorting residues and rubber parts as well as shredded materials from the automotive sector are treated in a shaft kiln. Here lime plays a decisive role.

New method utilises carbon-containing sorting residues and waste

With this method, the residual materials are mixed with coarse-ground lime and, using the counter flow principle, converted thermally and chemically in several stages, including gasification and pyrolysis.

The lime is used as a carrier medium for the plastics, as a catalyst for the process and as a binder for pollutants. No flue gas emissions are produced during the conversion.

The method is also suitable for problematic waste such as chlorine-containing plastics, contaminated soils and plastic-containing electrical scrap. Lime binds not only halogens and other harmful substances but also valuable materials contained in waste materials such as metals from electrical scrap.

These can later be separated and recycled. The new procedure is designed to supplement existing waste treatment systems.

The process produces a purified synthesis gas that can be utilised materially for producing basic chemical products or in engines. The first large-scale plant can recycle up to 50,000 tonnes of waste plastic per year. Ecoloop GmbH in Bad Harzburg, Germany, has developed the Ecoloop method in collaboration with other partners.

Im Focus: Making lightweight construction suitable for series production

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...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

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...

Im Focus: Deep inside Galaxy M87

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...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

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...

Im Focus: Microprocessors based on a layer of just three atoms

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...
