Thinking in terms of a product's life cycle, that is the whole supply chain supporting a product or service, allows a holistic perspective where not only the production and use of the product are considered, but also the acquisition of raw materials needed for the product and its waste management, as well as the transportation steps linking these stages. Life Cycle Assessment (LCA) is an analytical tool for the systematic environmental assessment of a product or service through its entire life cycle. Life Cycle Impact Assessment (LCIA) is one of the phases of LCA, where the technical information gathered on the product system is translated into meaningful information that can be interpreted and understood by the targeted audience. There are still some gaps in the representation of environmental issues by LCIA, namely the impacts derived from land use such as on biodiversity and soil quality. Land use impacts are particularly relevant in the resource extraction stage of most product systems (mining; agriculture; forestry), and their omission from LCA reduces the credibility of this tool.
Experts from different sectors (academia, government, industry) have been engaged in extensive debate under the umbrella of the UNEP/SETAC Life Cycle Initiative on the key elements that need to be included in land use impact assessment for LCA. As an outcome of this debate, a framework for land use impact assessment in LCA has been defined, and will be used as a starting point for the discussions. This workshop will initiate the inter-disciplinary process to define the indicators best suited to introduce impacts on biodiversity and soil quality in LCA.
The workshop is co-sponsored by the University of Surrey's Institute of Advanced Studies and UNEP/SETAC Life Cycle Initiative and the International Council on Mining and Metals, ICMM. The workshop has been organised by The Centre for Environmental Strategy (CES), within the University of Surrey.

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...
