Metals

Aluminium

After oxygen and silicon, aluminium is the third most abundant element in the earth’s crust and the most abundant metal with a proportion of 8 %. It can be recognized by its silvery white surface and its low weight. A thin oxide layer protects this metal from corrosion. It can be fully recycled without losing its original properties. The processing of aluminium scrap requires only about 10 % of the manufacturing energy compared to first production. In most industrial nations, one third of aluminium is produced from secondary raw materials (cf. PETERS, 2015). In addition to solid wood trays, ZEITRAUM also offers a variant with an aluminium tray for the tray of the PLAISIR occasional furniture.

Iron

The use of iron can be traced back to the year 4000 BC. Iron belongs to materials of natural origin. On the world market, 50 percent of it is made of scrap metal. The extraction of the metals is accompanied by severe environmental pollution, which, with the help of special exhaust gas purification systems, can be reduced to a level that is acceptable for the environment. Since 1990, Co² emissions from production have been reduced by 85 %, and the energy consumption by 70 %. Steel can be used to produce new components without any loss. The resulting slag is used for the production of cement. (cf. PETERS, 2015).

At ZEITRAUM, iron is used for the NOON luminaire series, the FORM chairs and the OKITO series.
