Extensive R&amp;D works have been done on red mud recycling and its possible usage. \u00a0I, like many reading this, have read many papers on this subject of how this can be achieved. However, they are mostly in documents and very few of them are commercially viable.\u00a0\u00a0 As a self-funded individual, my work will stand against any of the research I have read till date.<\/p>\n<p>Red Mud Recycling is possible in all its forms no matter where in the world it is being processed.<\/p>\n<p>After years of research and experiment on waste reutilization, I have identified a few uses for Red Mud that can bring a monetary value in the range of $16 to $70,500 per ton.<\/p>\n<p><strong>Building Material<\/strong><\/p>\n<p>The most common among the uses of red mud is using it as a building material.\u00a0 The use of Red Mud not only increases the compressive and tensile strength of products made by this method, it also serves as a colourant.<\/p>\n<p>Many have said what about the elevated levels of pH in Red Mud.\u00a0 Not many look at the level of pH in cement\/concrete that can be up to 13pH,\u00a0 The pH content of Red Mud is not more than that.<\/p>\n<p>The cement\/concrete has a higher cost than the Red Mud while being used as a building material. Red Mud is also ideally suited as an additive to: Alkali Activated Material.\u00a0 The high pH of Red Mud helps the chemical reaction to aid adhesion and setting time.<\/p>\n<p><a href=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-usage.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-1060\" src=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-usage.jpg\" alt=\"red mud usage\" width=\"224\" height=\"185\" \/><\/a> <a href=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-usage-2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-1059\" src=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-usage-2-300x146.jpg\" alt=\"red mud usage 2\" width=\"300\" height=\"185\" \/><\/a> <a href=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-usage-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-1058\" src=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-usage-1.jpg\" alt=\"red mud usage 1\" width=\"273\" height=\"188\" \/><\/a><\/p>\n<p>Various uses for Red Mud as a building product are, but not limited to the follows:<\/p>\n<ol>\n<li>Colourant<\/li>\n<li>Bricks<\/li>\n<li>Paving Slabs<\/li>\n<li>Roof tiles<\/li>\n<li>Block paving<\/li>\n<li>Pipes<\/li>\n<li>Bollards<\/li>\n<li>Benches<\/li>\n<li>Litter bins<\/li>\n<li>Sea defenses<\/li>\n<li>Central reservation dividers<\/li>\n<li>Kerbs<\/li>\n<li>Any other cement\/concrete construction as well as road and driveway bases<\/li>\n<\/ol>\n<p>A further benefit from using Red Mud as a building product is, it eliminates a phenomenon called Efflorescence. None of the samples (Images above) show any characteristics of Efflorescence.<\/p>\n<p>Red Mud can be used as a colourant to be mixed with resins to produce products with more decorative appeal than just cement\/concrete. They can be aesthetically used in kitchen worktops, bathroom shower trays, fire surrounds etc.<\/p>\n<p><strong>Elimination of Efflorescence <\/strong><\/p>\n<p>Efflorescence has been a visually distressing problem since we moved from caves to building our own homes.\u00a0 Efflorescence is seemingly endemic with all types of concrete paving and its presence on a recently laid patio or driveway can disappoint the homeowner. <strong>Efflorescence<\/strong>\u00a0is a crystaline deposit on surfaces of masonry, stucco or concrete. It is whitish in appearance, and is sometimes referred to as whiskers.<\/p>\n<p><a href=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-flooring-tiles.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-1056\" src=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/red-mud-flooring-tiles-227x300.jpg\" alt=\"red mud flooring tiles\" width=\"290\" height=\"294\" \/><\/a> <a href=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/slab-wth-cement.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone  wp-image-1063\" src=\"https:\/\/www.alcircle.com\/blog\/wp-content\/uploads\/2016\/05\/slab-wth-cement-300x227.jpg\" alt=\"slab wth cement\" width=\"300\" height=\"297\" \/><\/a><\/p>\n<p>In the photos of slabs we made from red mud we see no signs of efflorescence unlike these black slabs made with the same water, cement and aggregate. A sand substitute made from industrial waste can actually eliminate efflorescence as shown in our test pieces.\u00a0 This sand replacement costs no more than normal building sand and can be available as sharp sand for road and paving bases. Whilst this is only suitable for coloured products it eliminates an age old problem.<\/p>\n<p><strong>Plant base<\/strong><\/p>\n<p>Red Mud can also be used as a base for growing plants.\u00a0 We have been told a number of times that nothing will grow on Red Mud. However, with just a piece of toilet tissue as a filter seeds grow quite happily on a base of Red Mud. Also to make an advanced growing medium, red mud can be mixed with sewage; this has the effect of neutralizing each other and forms a growing medium or soil additive.<\/p>\n<p>We are now in a position to offer our services in the recycling of Red Mud. Our core products are made in the majority with Cement or on occasions with Alkali activated materials or Geopolymer with either 8 to 13 ph Red Mud or Neutralized Red Mud. We are offering a free service for the removal and recycling of Red Mud. Samples of our products are available for free but to manufacture sample pieces we require 50 to 100 kilo of Red Mud shipped to UK to manufacture samples.<\/p>\n<p>I hope readers will find this of interest.\u00a0 It is by no means everything that can be produced from red mud. Enough studies have been done till date for reutilization of red mud and its time we think about commercializing them.\u00a0 This will not only offer a viable solution to an age old environmental issue but also offer commercial benefits.<\/p>\n<p><em>(Gary J McNeish is a 58 year old, self-funded businessman from Manchester UK.\u00a0 He specializes in finding solutions to waste problems such as ethanol, cellulose fibers, bio coal\/mass, and pulp for papermaking from sewage.\u00a0 He has also done commendable work on extracting building materials from carbon block from the pyrolysis of waste tyres, low energy lighting, recycling of Red Mud etc. AlCircle however, has not checked the effectiveness of his project and applications.
