Casablanca – The OCP Group is accelerating the industrial deployment of a Moroccan-developed technology designed to reduce cadmium content in phosphoric acid and fertilizer products, reinforcing its position in the global fertilizer market while responding to rising environmental and regulatory pressures.

At the core of this development is the Jorf Lasfar industrial platform, one of the world’s largest phosphate processing hubs, where phosphate rock extracted from Moroccan mines is transformed into phosphoric acid and then into fertilizers exported to international markets. Within this integrated industrial chain, OCP has introduced advanced purification processes aimed at limiting cadmium content, a naturally occurring heavy metal found in phosphate rock.

Cadmium is present in varying concentrations depending on geological formations. During the chemical processing of phosphate rock into phosphoric acid, the element dissolves into the acid, creating a need for targeted removal before fertilizer production. Without such treatment, cadmium could accumulate in agricultural soils over time, raising environmental and health concerns and tightening regulatory scrutiny in key export markets.

To address this challenge, OCP has developed and industrialized two complementary technologies: co-crystallization and complexation. These processes are designed to separate cadmium from phosphoric acid and convert it into a stable solid form that can be safely extracted and stored. The purified acid is then used to produce fertilizers with significantly reduced cadmium content.

The development of these technologies is the result of long-term collaboration between OCP’s internal research and industrial teams and the Mohammed VI Polytechnic University. The partnership reflects a broader strategy linking scientific research with industrial application, allowing laboratory innovations to be scaled up into fully operational industrial systems.

According to information shared during industrial site visits and operational briefings, OCP tested dozens of technological approaches before selecting the current solution. Nearly fifty different methods were evaluated as part of a multi-year research program aimed at identifying an efficient, scalable, and economically viable cadmium removal process.

The selected technologies now enable OCP to achieve cadmium concentrations below 20 milligrams per kilogram of phosphorus pentoxide in finished fertilizers. This level is significantly lower than the threshold of 60 milligrams per kilogram set by European regulations, providing the group with a substantial compliance margin and strengthening its position in environmentally sensitive markets.

The industrial implementation of these processes at Jorf Lasfar marks a key step in transforming research outcomes into large-scale production capability. The platform integrates cadmium removal units directly into the phosphoric acid processing chain, ensuring that purification occurs before the material is used in fertilizer granulation.

OCP executives describe this transformation as part of a long-term strategic vision that places sustainability, innovation, and industrial sovereignty at the center of the group’s development model. The initiative is also aligned with growing global demand for fertilizers that meet stricter environmental standards while maintaining high agricultural productivity.

Beyond environmental compliance, the project reflects a broader industrial policy focused on technological independence. By developing proprietary solutions locally, OCP reduces reliance on external technologies and strengthens Morocco’s position as a producer of advanced industrial know-how rather than a mere exporter of raw materials.

Company representatives emphasize that the development process relied heavily on Moroccan expertise across multiple levels, including scientific research, engineering design, and industrial execution. Local companies were also involved in construction and implementation phases, contributing to job creation and the development of domestic industrial capacity.

In addition to reducing cadmium content in fertilizers, the process generates a solid by-product containing extracted cadmium. While this material is currently stored under controlled conditions, ongoing research is exploring potential future applications. Among the most discussed possibilities is its use in industrial processes linked to the global energy transition, potentially transforming what was previously considered waste into a valuable resource.

The industrialization of this technology also reflects OCP’s broader effort to integrate innovation into its production ecosystem. The group’s innovation strategy is closely tied to its research ecosystem, where institutions such as UM6P play a central role in bridging scientific discovery and industrial application.

Within this framework, OCP has positioned itself not only as a global fertilizer leader but also as a developer of advanced environmental technologies capable of addressing complex challenges in the phosphate industry. Cadmium reduction is one of several initiatives aimed at improving the environmental footprint of phosphate-based fertilizers while ensuring competitiveness in increasingly regulated international markets.

Industry experts note that cadmium management has become a global challenge for fertilizer producers, as regulatory standards continue to tighten and environmental awareness increases among agricultural stakeholders. In this context, OCP’s approach—combining chemical innovation, industrial scaling, and research collaboration—represents a model that could influence similar efforts worldwide.

At Jorf Lasfar, the full integration of cadmium removal technology into industrial operations signals the transition from experimental innovation to standardized production practice. This milestone underscores the group’s ability to translate complex scientific research into operational industrial systems at scale.

As global agriculture continues to evolve under environmental constraints, OCP’s low-cadmium fertilizer strategy highlights the growing intersection between industrial performance, scientific research, and sustainability requirements. The project illustrates how Morocco’s phosphate industry is moving toward higher value-added production while embedding environmental considerations into its core industrial processes.
