It is closely integrated with ore extraction and processing activities. Our corporate policy on tailings management is fundamental to the overall business strategy and is incorporated into sitewide policies, objectives, and plans.</p> <p> A Tailings Management Facility (TMF) can pose significant risks, as evidenced by global failures in mining and other industries. A TMF failure can lead to substantial loss of life, major destruction to infrastructure, and severe environmental damage. This policy ensures our TMFs are managed to minimise risks and impacts on the environment, local communities, and employees. We strive for high standards of operational efficiency and regulatory compliance throughout the lifecycle of TMFs, including project conception, design, construction, operation, closure, and post-closure.</p> <p> Our commitment to safe, responsible, and sustainable TSF management is integral to our operations, and we urge all employees, contractors, and partners to establish safe and sustainable tailing management practices.</p> <img class="img-responsive mb-4" alt="Closed Red Mud Disposal Area (RMDA) at Renukoot" src="/upload/Images/closed-red-mud-v1.jpg" title="Closed Red Mud Disposal Area (RMDA) at Renukoot"> <p style="font-size: 14px; margin-top: -20px; "> Closed Red Mud Disposal Area (RMDA) at Renukoot</p> <h3> How we manage tailings</h3> <p> At Hindalco, we recognise our responsibility to maximise the value derived from the minerals and materials that we produce, prioritising safety and sustainability. Major tailings generated at Hindalco is bauxite residue that is produced during Bayers process (digestion stage) in Alumina refineries.</p> <p> We have established Dry Stacking Facilities (DSF) with press filtration technology capable of providing filter cake with moisture content as low as 25 to 28%.  The residue is then shifted to Bauxite Residue Disposal Areas (BRDA) also called as RMDA (Red Mud Disposal Areas) by conveyors or through tippers, that are completely covered.</p> <img class="img-responsive mb-4" alt="Plate & Frame filter at Utkal that increases solid concentration upto 75-78%." src="/upload/Images/plate-frame-utkal-v1.jpg" title="Plate & Frame filter at Utkal that increases solid concentration upto 75-78%."> <p>We have achieved 100% utilisation of bauxite residue at three of our four refineries by co-processing it in cement industries for four consecutive years, starting from FY 2020-21. Several innovative projects like manufacturing of polymer composite, and construction aggregate, in-situ neutralisation by flue gas, embankment/subgrade construction for Roads, backfilling are in experimental/pilot stage</p> <p> We have closed and rehabilitated inactive facilities at Muri by biochemical, biological and vegetative remediation process.  Each of the facilities are meticulously regulated, monitored, and operated in accordance with local laws, regulations, internal standards, and other industrial best practices and relevant requirements. </p> <h3>What is GISTM? </h3> <p> The Global Industry Standard on Tailings Management (GISTM) is a robust framework developed to enhance the safety, sustainability, and overall management of tailings facilities in the mining industry. GISTM strives to achieve the ultimate goal of zero harm to people and the environment. This is reinforced by an integrated approach to tailings management. The standard aims to prevent catastrophic failure and enhance the safety of mine tailings facilities across the globe. It embodies a step change in terms of transparency, accountability and in safeguarding the rights of people affected by the project.<strong> </strong></p> <p> Our commitment of conforming to the GISTM presents an opportunity to continuously refine our comprehensive tailings management practices and ensure a greater level of transparency. </p> <p style="font-size: 14px; margin-top: -20px; ">Plate & Frame filter at Utkal that increases solid concentration upto 75-78%.</p> <p> We adhere to the highest engineering standards and employ best-in-class safety and environmental management practices. Regular reviews are conducted through esteemed independent third parties. Our unwavering goal is to prevent harm to both nature and people, and we are constantly enhancing our systems and processes. </p> <img class="img-responsive mb-4" alt="" src="/upload/Images/rehabilitation-muri-RMDA-v1.jpg" title="Rehabilitation at Muri RMDA">  </div> </div> <div class="grid_3 innerpage_RHS""> <div class="in_section"> <div class="in_section"> <h3>In this section</h3> <ul> <li class="aboutLink"> <a href="http://www.hindalco.com/upload/pdf/hindalco-tailings-management-policy.pdf" target="_blank">Tailings Management policy</a></li> <li class="aboutLink"> <a href="http://www.hindalco.com/upload/pdf/gistm-public-disclosure.pdf" target="_blank">GISTM Public Disclosure</a></li> <li class="aboutLink"> <a href="http://www.aluminiumtoday.com/news/hindalco-becomes-1st-first-ever-company-to-achieve-100-red-mud-ut" target="_blank">Hindalco becomes first-ever company to achieve 100% red mud utilisation worldwide across three of its refineries</a></li> <li class="aboutLink"> <a href="http://www.icsoba.org/proceedings/41st-conference-and-exhibition-icsoba-2023/" target="_blank">Red to Green Projects in Alumina Refineries of Hindalco</a></li> <li class="aboutLink"> <a href="http://www.sciencedirect.com/science/article/abs/pii/S0301751612001214" target="_blank">Special cement developed by BHU and Hindalco</a></li> </ul> </div> <div class="in_section"> <div class="in_section" style="display:none;"> <h3><img alt="" src="/Images/top_nav_contact-us.jpg">Contact information</h3> <div class="in_section"> <ul> <li><a href="/contact-us/contact-addresses#Investors ">Investors </a></li> </ul> </div> </div> </div> </div> <div class="in_section" style="display:none;"> <h3><img src="/Hindalco/images/brands_icon.gif">Hindalco Brands</h3> <div class="imagebg_box"> <div class="slider"> <div id="Div1" class="flexslider"> <ul class="slides"> <li><img src="/Hindalco/images/hindalco_brands01.jpg" class="max-img"/></li> <li><img src="/Hindalco/images/hindalco_brands02.jpg" class="max-img"/></li> <li><img src="/Hindalco/images/hindalco_brands03.jpg" class="max-img"/></li> </ul> </div> </div> </div> </div> <div class="in_section"> </div> <div class="news" style='display:none'> <h3><img alt="" src="/Hindalco/Images/news_icon.gif">Latest updates</h3> <div class="newsbg_box"> </div> </div> </div> </section> </div> </div> <div class="clear"> </div> </section> </form>  <footer class="footer"> <div class="container"> <div class="float_left copyright">Copyright 漏 <span id="year-foot"></span> Hindalco Industries Ltd. | <a href="/legal-disclaimer">Legal disclaimer</a> | <a href="/beware-of-fraudulent-job-offers">Beware of fraudulent job offers</a> | <a href="https://www.hindalco.com/data-privacy-policy" target="_blank">Data Privacy Policy</a></div> <div class="clear"></div> </div> </footer>  <script type="text/javascript" src="/assets/js/jquery.min.js"></script> <script src="/assets/js/bootstrap.min.js" type="text/javascript"></script> <script type="text/javascript" src="/assets/js/jquery.slitslider.js"></script> <script src="/assets/js/custom.js" type="text/javascript"></script> <script type="text/javascript"> {document.getElementById("year-foot").innerHTML = (new Date().getFullYear());} function restoreli(type, li_id,spn_id) { if (type != "") { document.getElementById(type).style.visibility = "hidden"; } document.getElementById(spn_id).className = ""; } function showSubMenuli(type, li_id,spn_id) { if (type != "") { document.getElementById(type).style.visibility = "visible"; } document.getElementById(spn_id).className = "menu_active"; } </script> <script type="text/javascript" src="/assets/js/jquery.lazyload.js"></script> <script type="text/javascript"> $(function() { $(window).bind("load", function() { var timeout = setTimeout(function() { $("section.lazy").trigger("sporty") },800); }); $(".bg-img.lazy").lazyload({ effect : "fadeIn", event : "sporty" }); }); </script> <script language="JavaScript" type="text/javascript"> $(document).ready(function() { $('.go_btn').click(function() { debugger; //Top1_txtsearch if ($('#txtsearch').val().length > 0 && $.trim($('#txtsearch').val().toLowerCase()) != 'search') { if (CheckChars() == true) { var s= $('#txtsearch').val(); window.location.href = '/search/' + $('#txtsearch').val(); return true; } } else { alert('Please enter search keywords'); $('#txtsearch').focus(); return false; } return true; }); }); function clickBtn(e) { var i = 0; var iChars = "!#^&*\\\';,/{}|\<>?" if (window.event) // IE { if (e.keyCode == 13 && $('#txtsearch').val().length > 0 && $.trim($('#txtsearch').val().toLowerCase()) != 'search') { for (i = 0; i < $('#txtsearch').val().length; i++) { if (iChars.indexOf(document.getElementById('txtsearch').value.charAt(i)) != -1) { alert("Search string has special characters.
