Although this may seem shocking, <strong>gold medals are not made of gold at all!<\/strong> They are produced from top-grade silver (&gt;995), which is then gold plated, this time with real gold at a symbolic 6g. Interestingly, gold medals have not been gold for over 100 years - the last time pure Olympic gold was awarded to athletes was at the 1912 Stockholm Games.<\/p>\n<p>The situation is different for Olympic silver medals, which are silver not just in name. Like the most valuable pucks, they are also <strong>Olympic silver is produced from silver of a purity &gt;995<\/strong>.

The breakthrough came during the <strong>2016 Rio Games, when the silver and bronze medals were made in 30% from recycled metals<\/strong>. These medals were hung on ribbons, which in turn were produced from recycled bottles.<\/p>\n<p>A step further was taken by the organisers of the 2021 Tokyo Olympic Games. - They decided to make <strong>medals made from 100% recycled electro-waste material<\/strong>. The entire Japanese public was involved in the collection of this electro-waste, donating old phones, computers and small electronics for months. From the electro-waste collected <strong>4.1 tonnes of silver, 2.7 tonnes of bronze and more than 30 kg of gold were recovered, from which around 5,000 medals could be cast.<\/strong><\/p>\n<p>Olympic medals are just one of the non-obvious uses of recycled materials. <a href=\"https:\/\/ekobezkantow.pl\/blog\/co-powstaje-z-recyklingu\/\">Check out what else is made from recycling!<\/a><\/p>\n<\/div><div class=\"vc_custom_heading_wrap\"><div class=\"heading-text el-text\" ><\/p>\n<h2>Medals not only recycled, but also... refurbished<\/h2>\n<p>\n<\/div><div class=\"clear\"><\/div><\/div><div class=\"uncode_text_column\" ><p>The idea of casting Olympic medals from recycled metals continued <strong>at the 2024 Olympic Games in Paris.<\/strong> In addition to recycled silver, gold, copper, tin and zinc, <strong>They also included ... iron fragments from the Eiffel Tower.<\/strong> They were obtained during the renovation and then sunk inside each of the medals.
