Proceedings of The International Conference on Phosphates : Fundamentals, Processes and Technologies October 15-17, 2020 MOHAMMED VI POLYTECHNIC UNIVERSITY THE PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON PHOSPHATES : FUNDAMENTALS, PROCESSES AND TECHNOLOGIES 15 - 17 OCTOBER 2020 1 October 15-17, 2020 Proceedings of The International Conference on Phosphates : Fundamentals, Processes and Technologies PREFACE Phosphorus, naturally present in the earth in the form of phosphate ores, is an essential element for life; its cycle is unique among the major biogeochemical cycles because it does not have a gaseous component. As a result, it doesn’t affect the atmosphere. It is a source of life for living beings: phosphate groups are constituents of bones and DNA. It is present in the various processes of the synthesis of living matter and intervenes as a support for the genetic heritage (nucleic acids) and plays an important role in the synthesis of sugars and proteins (enzymatic reactions). Phosphates are used mainly in agriculture, as fertilizer, to ensure the growth of plants and to enrich fruits and vegetables with sources of phosphorus. They can also bring nitrogen (ammonium phosphate), calcium (calcium phosphates) and aluminum (aluminum phosphate) to the plant. Phosphates are also used in many other special applications including food additives, materials, catalysis and water treatment thanks to research contribution which extends the phosphate applications scope. R&D is essential for the development of countries, companies and communities, but it can only succeed and bear fruit through close collaboration between researchers from different universities and between academic and industrial institutions. This second edition of the International Conference on Phosphates (ICP2), which brought together multidisciplinary scientists and researchers from different countries for the sole purpose of sharing and disseminating scientific and technical knowledge and contributing to the enrichment and progress of knowledge, is a good example of such collaboration. It highlights the close and necessary involvement of researchers and industry practitioners to foster the emergence of a better, rational and sustainable world. In this context, Phosphate Research Network (PhoResNet) organizes in collaboration with Mohammed VI Polytechnic University a biennial event “Phosphate Days” in its 2nd edition “Phosphate Days 2020” which provides a unique setting and space to bring together Scientists and Engineers, from all over the world to exchange about research new findings for advancing scientific and technological knowledge in a friendly atmosphere of collaboration and partnership. PhoResNet is an international network gathering researchers, scientists and Professionals working on phosphates, phosphate derivatives and phosphorus compounds. One of the main objectives of PhoResNet is to promote a high quality of R&D in all scientific and technological fields related to Phosphates by allowing a high visibility to scientific production at the international level and fostering its impact through the creation of synergies between university researchers and industry. Mohammed VI Polytechnic University is a world-class institution focusing on research and innovation. Founded for research purposes, this university offers an exceptional environment for cutting-edge training and academic excellence with the aim of positioning Morocco as an international platform for innovation to take on the African continent’s big challenges and issues. The university is open to international collaborations and creates partnerships to bridge between Morocco, Africa and the rest of the world. Phosphate is a fertilizer, it is also a fertile field for research: while browsing “The International Conference on Phosphates (ICP2)” program, we can only be impressed by the many applications of phosphates and the diversity of fields of scientific investigation that researchers from various specialties can handle. These proceedings contain the papers presented at “The International Conference on Phosphates (ICP): Fundamentals, processes and technologies” held in a virtual version at the Mohammed VI Polytechnic University from 15 to 17 October 2020. I hope that the results presented in this Conference can contribute to the progress of science, enhance the knowledge and lead to development of new technologies for the betterment of all humankind.
