<strong>Green</strong> Ideas textile colouring Vegetable colours for textiles are becoming more and more popular. Soon it will be possible to colour textiles industrially using onion skins, bark or black tea pomaces.. bio bags The new weaving method Double Twist Technology, also invented by VPZ Graz; every thread is entwined around the next twice. This way, less material than before creates more break-resistant strength in the natural material. wood plastic composite A totally new class of material that is being researched, amongst others, by the competence centre Wood in Linz, is called wood plastic composite: The combination of wood and plastic allows researchers to combine the two materials’ positive attributes and reduce the negative characteristics. Algen statt Styropor Schaumstoff aus Algen brennt nicht, ist gut kompostierbar und weist gute Wärmedämmungswerte auf. Außerdem wird das Produkt des Verspackungszentrum Graz mit Luft – und nicht wie Styropor mit FCKW – aufgeschäumt. 14 LOCATIONAUSTRIA 02/2006
CHRISTIAN HOUDEK Fernwärme Wien: Battery Recycling Thermal battery recycling in the Simmeringer Haide plant of Fernwärme Wien stands for: • The safest way to recycle spent batteries • No environmental risk caused by mercury and o other heavy metal from spent batteries • A possibility to separate non-sorted batteries in • different recyclable fractions • A combination of best available battery treatment • and flue gas cleaning technology using a plant • interface with the main hazardous waste treatment plant Technical highlights Thermal treatment of alkaline and zinc-carbon • batteries at above 700 °C • Battery throughput: 450 kg/h • Annual capacity: 3,000 t • Energy consumption 1,200 MJ/t • Extracted average mercury quantity: 120 g/t • 77% of the spent batteries can be recycled after the • process Despite a legal ban in the EU mercury containing batteries are still manufactured in many countries and will continue to be available in the foreseeable future. As a result many non-rechargeable batteries still contain between 100 and 150 ppm of mercury and other heavy metals. Mercury is a dangerous toxin for humans that causes cancer and harms the nervous system. Furthermore, it is pestilent for fauna and flora. It is thus inevitable to avoid emissions of mercury as well as other heavy metals. At the Simmeringer Haide plant of Fernwärme Wien a battery recycling plant is operated ensuring an environmentally sound disposal of these dangerous environmental toxins. After this pre-treatment the residual contents of spent batteries (predominantly zinc, manganese and iron) can be recycled and re-used as a secondary raw material. Prior to the recycling process the collected spent batteries need to be separated in order to allow a type-specific recovery of the wide variety of materials. Fernwärme Wien offers the service for accurate separation of the different battery types. FERNWÄRME WIEN PROMOTION The process flow diagram to the right shows that pre- sorted batteries (zinc-carbon and alkali-manganese) are first stored and filled into a feeding bin. Transported by a conveyor and feeding system they are brought into the rotary kiln where they are treated at temperatures above 700 °C for about one hour. In this process the spent batteries disintegrate, carbon, zinc and manganese are oxidised and mercury as well as heavy metals leave the kiln with the dust fraction of the flue gas. After a post combustion the solids (i.e. the recyclable fraction) are shredded, sieved and divided by a magnetic separator into a zinc/manganeseoxide fraction and a scrap metal (steel) fraction. These fractions can be recycled in raw material industry for the production of zinc and steel. The remaining volatiles are first dedusted in a hot gas cyclone and then cleaned in a three stage flue gas treatment system. Large amounts of hazardous contents (such as mercury) are washed out of the flue gas. Fernwärme Wien uses best facilities for the treatment of the remaining flue gas and waste water. The flue gas is connected to the post combustion system of the main hazardous waste kiln and is treated at 1,200 °C again. Afterwards it passes the same multi-stage gas cleaning system including scrubbers, activated carbon filter and nitrogen oxide removal as the flue gas out of the main hazardous waste treatment plant. Similarly the waste water from the battery recycling process is treated in the main waste water treatment facility. The remaining filter cake is disposed of in an environmentally sound underground landfill. Since the Simmeringer Haide plant fulfils the latest and strictest emission standards within the EU battery recycling by Fernwärme Wien can be counted as one of the safest ways to treat spent batteries.
