en.Wedoany.com Reported - Emmerson, a London-listed company, has been granted patent protection by the UK Intellectual Property Office (UK IPO) for its patent application covering the Khemisset Multimineral Process (KMP). The patent, titled "Treatment of Evaporite Minerals" (Application No. 2315003.0), provides intellectual property protection for the core KMP process and its optimized derivatives.
Originally developed by Emmerson for its Khemisset potash project in Morocco, the KMP is expected to have potential applications in more potash deposits globally in the future. Through its advisory firm Gill Jennings & Every, Emmerson has filed a series of patent applications aimed at protecting its intellectual property in key commercial regions.
Emmerson previously described the KMP as a "breakthrough" processing route for the Khemisset project. By adopting the KMP process, the project reduces water consumption by 50%, increases the recovery rate of muriate of potash from 85% to approximately 91%, and produces two new high-value slow-release multi-nutrient fertilizers: struvite and vivianite.
Beyond commercial value, these fertilizer products offer significant environmental and sustainability advantages due to their slow-release properties, which reduce phosphate runoff into water bodies and lower the frequency of application for farmers.
On April 30, 2025, the company's direct and indirect subsidiaries, Khemisset UK and Potasse de Khemisset, submitted an arbitration request to the International Centre for Settlement of Investment Disputes (ICSID), which was registered by the ICSID Secretary-General on May 23, 2025. The claimants filed their statement of claim on March 27 of this year, accompanied by documentary evidence, witness statements, and expert evidence. The claimants seek damages of $1.22 billion (net after local taxes, including interest), alleging that Morocco violated its obligations under the Agreement between the Government of the United Kingdom of Great Britain and Northern Ireland and the Government of the Kingdom of Morocco for the Promotion and Protection of Investments (BIT), including the expropriation of the project in breach of Article 6(1) of the BIT, and failure to provide fair and equitable treatment, full protection and security to the claimants and their investments, and failure to avoid impairing the claimants' investments through discriminatory measures.
