Australia: Boral's Berrima cement plant team has successfully concluded its annual kiln shutdown and maintenance period. The producer invested US$13.1m and 100,000 working hours over a period of three weeks. The project required coordination with 50 different contracting companies to undertake mechanical repairs and replace the kiln refractory, which is crucial for protecting the kiln shell from heat damage and ensuring operational safety. Employing Cement 4.0 technology and advanced diagnostic tools, the team efficiently identified the necessary repairs. About 300 employees and contractors were engaged in the specialist tasks, facilitating a rapid resumption of kiln operations.

Kenya: East African Portland Cement Company (EAPCC) says that it is ready to resume full-scale cement production at its 600,000t/yr Athi River cement plant. The Standard newspaper has reported that the plant is currently operating at 50% capacity, following refurbishment. EAPCC replaced a 16m-long section of kiln shell in the plant's clinker line, at a cost of US$3.5m. Managing director Oliver Kirubai said that the company raised the funds through the sale of land located in Athi River.

Kirubai said "Our employees have cut back a lot, in a situation where we have been struggling even to pay their salaries. We are now back on our feet." He added "A number of companies owed us millions of Shillings. They have been ordered to pay us by the government. If they honour the agreement, the problem we are facing will be a thing of the past.”

EAPCC says that it expects the scale-up of production at the Athi River plant to help lower the cost of cement for its customers.

Uzbekistan: Bekabadcement is carrying out a 'large-scale' upgrade to its 0.7Mt/yr Bekabadcement plant in Tashkent Region. The producer said that the upgrade involves a 20% capacity expansion of the plant's production line to 2500t/day. Austria-based Unitherm CemCon supplied burners for the upgraded line, while China-based Beijing Triumph International Engineering supplied heat exchanger components and a KC 4.1-0955 cooler. The upgrade also involves the installation of new kiln lining, and will transition the plant's cement production from wet to dry process. Germany-based Christian Pfeiffer previously upgraded the Bekabad cement plant's grinding unit in April 2023.

General director Vasily Korobkin "We see that (parent company) United Cement Group (UCG) is interested in the modernisation and development of the enterprise. The group adheres to international standards, so all plans for the development of the plant are built accordingly." He concluded "We expect to become a modern and successful enterprise in Uzbekistan which is capable of becoming a major player in the cement industry of Central Asia.”

Kenya: East Africa Portland Cement began work to replace a 16.5m-length of kiln shell at its Athi River cement plant at the end of July 2022. The producer says that the project will increase the kiln line’s capacity by 1400t/day.

Managing director Oliver Kirubai said "Due to the high costs of energy and an old clinker line, the board has prioritised efficiency and reliability of our integrated plant operations to drive cost optimisation.”

Kyrgyzstan: United Cement Group (UCG) subsidiary Kant Cement has begun installation of a lining on its Kant cement plant’s rotary kiln in order to reduce losses and improve the efficiency of the plant. The producer expects the lining to raise its kiln’s temperatures by 100°C. It consists of wear-resistent RMAG–H2 bricks and HALBOR–400 refractory bricks.

UCG said “Energy efficiency and energy saving are among the most important factors for the successful implementation of ongoing economic and social reforms.”
