He was formerly Vice President in Operations Services at BHP and has been in the mining and resources industry for over 20 years. Mark studied Metallurgy at the University of Wollongong, obtaining a Bachelor in Materials Engineering and then a Masters in Engineering (specializing in Metallurgical processing). He is a global mining executive with a proven record of sustainably delivering innovative solutions to enterprise level issues, while building and inclusive and motivated team culture. <\/p>\n\n\n\n<p>Mark is actively working to support the Australian energy transition. Australia has an urgent need to improve the smooth integration of renewable energy into our energy grid and, at the same time, has a rich and deep mining legacy which, when partnered with the right clean technology, can form part of the solution to rapid and economic decarbonisation.<\/p>\n\n\n\n<div id='buzzsprout-small-player-limit-5-artist-mark-swinnerton'><\/div><script type='text\/javascript' charset='utf-8' src='https:\/\/www.buzzsprout.com\/2083595.js?artist=Mark+Swinnerton&#038;container_id=buzzsprout-small-player-limit-5-artist-mark-swinnerton&#038;limit=5&#038;player=small'><\/script>\n\n\n\n<h3 class=\"wp-block-heading\">Resources Related to the Episode<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Wollongong Australia<\/strong>\n<ul class=\"wp-block-list\">\n<li>About Wollongong, Australia and its history [<a href=\"https:\/\/www.visitwollongong.com.au\/\" target=\"_blank\" rel=\"noreferrer noopener\">Official Tourism Site<\/a>] [<a href=\"https:\/\/en.wikipedia.org\/wiki\/Wollongong\" target=\"_blank\" rel=\"noreferrer noopener\">Wikipedia<\/a>] <\/li>\n\n\n\n<li>The <a href=\"https:\/\/en.wikipedia.org\/wiki\/2022_UCI_Road_World_Championships\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>World Ccycling Championships 2022<\/strong><\/a><\/li>\n\n\n\n<li>Wollongong&#8217;s <a href=\"https:\/\/wollongongresources.net.au\/history\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>mining history<\/strong><\/a><\/li>\n\n\n\n<li>The <strong><a href=\"https:\/\/www.uow.edu.au\/\" target=\"_blank\" rel=\"noreferrer noopener\">University of Wollongong<\/a><\/strong><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>For those interested in purchasing your own <strong>selfie stick<\/strong>, <a href=\"https:\/\/www.digitalcameraworld.com\/buying-guides\/best-selfie-sticks\" target=\"_blank\" rel=\"noreferrer noopener\">here&#8217;s a review <\/a>of the best selfie sticks for your smartphone or other devices<\/li>\n\n\n\n<li>Some of the companies Mark worked in:\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/www.bhp.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">BHP&#8217;s Official Website<\/a><\/strong> <\/li>\n\n\n\n<li><strong><a href=\"https:\/\/www.bluescope.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">BlueScope<\/a><\/strong> <\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>We refer to <strong><a href=\"https:\/\/petermbach.com\/index.php\/podcast\/017-mohan-yellishetty\/\" data-type=\"page\" data-id=\"1035\" target=\"_blank\" rel=\"noreferrer noopener\">Episode 17 with Mohan Yellishetty<\/a><\/strong>, which was also the first episode about the abandoned mines story on the podcast.
