The safe disposal of Spent Pot Linings (SPLs), the waste material generated in the de-lining of steel containers following the aluminium (AL) smelting electrolysis process, is a major environmental challenge as highly toxic & hazardous substances are absorbed into the cell lining (made up of carbon & refractory (ceramic) layers) in the process – making disposal extremely hazardous & expensive. Existing SPL disposal techs (e.g. Macro encapsulation, vitrification), do not look to recover metals or other valuable materials, but simply treat the material to reduce toxicity for landfill disposal. Ultromex have successfully completed PoC work around a novel treatment process which successfully makes the carbon layer from a SPL inert with the potential to re-use in other applications (e.g. new anodes). In order to develop a complete viable solution, Ultromex now seek to complete a 12 month Industrial Research project to investigate the feasibility of treating & de-contaminating the two refractory layers, through the use of novel proprietary mechanical & chemical treatment processes, at a single location & prove they are able to separate all streams – producing inert refractory material (that can be used to make new brick for the cathode cell or used in a wide range of brick products for the construction industry) & inert carbon material (used as an addition for either anode or cathode production or as a high quality fuel). If successful, Ultromex will revolutionise the AL smelting industry by providing a viable closed loop process to a major challenge.

废罐衬里（SPLs）的安全处理是一项重大的环境挑战，因为在铝（AL）冶炼电解过程中，钢容器的衬里脱落产生的废物，在该过程中，剧毒和有害物质被吸收到电池衬里（由碳和耐火（陶瓷）层组成）中，使得处理极其危险和昂贵。现有的SPL处理技术（如宏观封装、玻璃化）不寻求回收金属或其他有价值的材料，而只是简单地处理材料以减少填埋处置的毒性。Ultromex已经成功地完成了PoC工作，围绕一种新的处理工艺，成功地使SPL的碳层变得惰性，并有可能在其他应用中重复使用（例如新阳极）。为了开发一个完整可行的解决方案，Ultromex正在寻求完成一项为期12个月的工业研究项目，通过使用新颖的专有机械和化学处理工艺，研究处理和去除两个耐火层污染的可行性。在一个单一的位置，并证明他们能够分离所有流-生产惰性耐火材料（可用于制造阴极电池的新砖或用于建筑行业的各种砖产品）和惰性碳材料（用作阳极或阴极生产的添加剂或作为高质量燃料）。如果成功，Ultromex将通过提供可行的闭环过程来解决重大挑战，从而彻底改变铝冶炼行业。
