KUALA LUMPUR, 19 July 2025 — Cahya Mata Sarawak Bhd, through its subsidiary Cahya Mata Cement Sdn Bhd, has awarded a RM673 million contract to Sinoma Industry Engineering (M) Sdn Bhd to construct a new clinker production line at its Mambong Integrated Plant in Kuching.
The new 6,000-tonnes-per-day Clinker Line 2 is expected to more than double the plant’s annual clinker capacity from 900,000 tonnes to 1.9 million tonnes. According to a filing with Bursa Malaysia, the project aims to improve cost efficiency and eliminate the need for future clinker imports, thereby significantly reducing the group’s carbon footprint.
Construction is scheduled to begin in August 2025, with clinker production expected to start by April 2027 and full commissioning by June 2027.
Group managing director Datuk Seri Sulaiman Abdul Rahman Taib said the project is a key milestone in strengthening Sarawak’s cement supply chain, increasing capacity, reducing dependency on imports, and ensuring future supply stability.
“Beyond meeting production goals, this project reflects Cahya Mata’s ambition to become one of the region’s most sustainable cement producers,” he said.
The facility will feature advanced environmental and energy-efficient technologies, including a waste heat recovery system capable of generating up to six megawatts of power, and a high-performance dust filtration system designed to reduce emissions to less than half the current regulatory limit.
Additionally, the clinker line will use high-efficiency equipment to lower energy consumption and CO₂ emissions, while integrating locally sourced alternative materials and fuels to reduce reliance on fossil fuels.
At peak construction, the project is expected to create up to 500 jobs and provide economic benefits to local businesses, particularly in the Padawan and Kuching areas.
