removal<\/h2>\n<p>Mercury switches and condensers are removed from refrigerators and coolers during the hazardous-substance removal process. The main emphasis is on separately capturing CFCs and HCs from the coolants and propellants, which are later destroyed through thermal processing. Two stages are involved:<\/p>\n<h3>Stage 1 \u2013 Extracting coolant from the cooling circuit<\/h3>\n<div style=\"width: 330px\" class=\"wp-caption alignright\"><img wpfc-lazyload-disable=\"true\" loading=\"lazy\" decoding=\"async\" class=\"ngg-singlepic ngg-right \" src=\"https:\/\/www.elektro-ade.at\/wp-content\/gallery\/verwertung\/kuehlgeraete2.jpg\" alt=\"kuehlgeraete2\" width=\"320\" height=\"240\" \/><p class=\"wp-caption-text\">Recycling of coolers UFH, Kematen (\u00a9 UFH RE-cycling GmbH, 2018)<\/p><\/div>\n<p>&nbsp;<\/p>\n<p>In the first stage of the process, capacitors, mercury switches and glass plates are removed. The CFC\/HC oil mixture is then sucked out of the cooling circuit, and the compressor is removed. The compressor consists mainly of ferrous metals, and is reused for secondary raw materials.<\/p>\n<p>In a further step, CFCs and HCs are separated out of the compressor fluid through a cryocondensation process, or through a special heat and pressure process.<\/p>\n<p>Once the CFCs and HCs have been removed, the compressor fluid can be reused. CFCs are \u201ccracked\u201d in a high-temperature furnace, i.e. broken down into hydrofluoric and hydrochloric acids, thereby rendering them harmless. HCs are processed thermally.<\/p>\n<p>The first stage of recycling refrigerators and freezers is handled by a small number of facilities in Austria, e.g. UFH RE-cycling GmbH in Kematen (<a href=\"http:\/\/www.ufhrecycling.at\">www.ufhrecycling.at<\/a>) and Energie AG Ober\u00f6sterreich Umwelt Service GmbH in Timelkam.<\/p>\n<p>&nbsp;<\/p>\n<h3>Stage 2 \u2013 Final processing<\/h3>\n<div id=\"attachment_10516\" style=\"width: 335px\" class=\"wp-caption alignright\"><img wpfc-lazyload-disable=\"true\" loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-10516\" class=\"ngg-singlepic ngg-right wp-image-10516 size-full\" src=\"https:\/\/www.elektro-ade.at\/wp-content\/uploads\/2018\/09\/kuehlgeraeterecycling1.jpg\" alt=\"\" width=\"325\" height=\"450\" srcset=\"https:\/\/www.elektro-ade.at\/wp-content\/uploads\/2018\/09\/kuehlgeraeterecycling1.jpg 325w, https:\/\/www.elektro-ade.at\/wp-content\/uploads\/2018\/09\/kuehlgeraeterecycling1-217x300.jpg 217w\" sizes=\"auto, (max-width: 325px) 100vw, 325px\" \/><p id=\"caption-attachment-10516\" class=\"wp-caption-text\">Recycling of coolers, refrigerators and freezers, Kematen (\u00a9 UFH RE-recycling GmbH, 2018)<\/p><\/div>\n<p>The second step in processing refrigerators and freezers is to recover the CFCs or hydrocarbons (HCs) from the insulating foam \u2013 see \u201c<a href=\"https:\/\/www.elektro-ade.at\/en\/recycling-and-reuse\/pur-powder\/\">Recovering PUR powder<\/a>\u201d.<\/p>\n<p>An airlock input system is used to direct the appliances through the initial (cross-flow shredder) and final (shredder) breakdown steps. The airlock system is necessary because the second stage of processing takes place in a vacuum so that the CFCs and HCs released during the breakdown process cannot escape into the environment.<\/p>\n<p>The PUR foam which contains CFCs and HCs is separated out, then processed further as described <a href=\"https:\/\/www.elektro-ade.at\/en\/recycling-and-reuse\/pur-powder\/\" target=\"_blank\" rel=\"noopener noreferrer\">here<\/a>.
