CIMPOR Calcined Clay Facility
In partnership with
DEHA TECH, Viram Mariv is delivering protective surface solutions for the CIMPOR Calcined Clay Facility in Tema, Ghana. This 1,280‑ton‑per‑day plant for CIMPOR Global Holdings is expected to reduce up to 440,000 tons of CO₂ annually when it becomes operational in 2025. Our work mirrors the sandblasting and protective‑coating standards showcased on Viram Mariv’s LNG Tema project page (link to LNG Tema project).
Viram Mariv provides end‑to‑end industrial surface protection on the CIMPOR Calcined Clay Facility, focusing on durable corrosion control and long‑term asset protection in a coastal, high‑humidity environment. Our scope includes sandblasting, rust removal, industrial coating of structural steel, and protective painting of tanks, pipelines, and equipment. These interventions help extend asset life, improve safety, and support the plant’s low‑carbon mission.
Beyond its green credentials, the project addresses critical economic challenges in West Africa. Because Ghana lacks large limestone reserves, the industry has historically relied on expensive clinker imports. This facility utilizes locally sourced clay, which:
The successful realization of this landmark facility relies on the technical synergy between its partners.
Deha Tech is spearheading the construction and mechanical assembly, including the installation of the 81m-tall flash calciner and over 6,000 tons of structural steel. Supporting these efforts,
Viram Mariv provides critical expertise in specialized equipment and engineering services, ensuring that the facility meets the highest international standards of precision and safety.
This project serves as a global blueprint for how emerging economies can leverage local resources and cutting-edge technology to lead the transition to a Net-Zero future.
The global cement industry is witnessing a transformative shift toward decarbonization, with Ghana at the center of this revolution. Through a strategic partnership between Viram Mariv and Deha Tech, the construction of Cimpor Global Holdings’ new facility in Tema is set to become the world’s largest newly-built calcined clay plant.
Unmatched Scale and Capacity
Located in the industrial hub of Tema, the plant features a massive daily production capacity of 1,280 tons (1,280tpd). This facility is specifically engineered to produce "activated clay" using advanced flash activator technology, which will be integrated into Cimpor’s cement production to significantly reduce the clinker factor often below 50%.
Slashing CO2 Emissions in Ghana
The primary driver behind this investment is environmental sustainability. Once fully operational in 2025, the
Tema plant is projected to:
Reduce CO2 emissions by up to 440,000 tons annually.
Lower the carbon footprint of cement by roughly 40% compared to traditional Ordinary Portland Cement (OPC).
Minimize energy consumption by activating clay at much lower temperatures than those required for traditional clinker production.
