Canada: St Marys Cement, part of Brazil-based Votoronatim Cimentos, has installed a US$19.9m wet scrubber at its Bowmanville cement plant in Ontario. The installation will reduce the plant’s sulphur dioxide (SO₂) emissions by 90%. The producer says it is the first wet scrubber installed at a cement plant in Canada.

Operations Manager Jim Storey said “This investment in technology to improve the plant’s environmental performance has proven to be effective in removing SO₂ produced in the cement manufacturing process. We are also pleased that the scrubber was assembled on-site and installed by local Ontario contractors and crews during our annual scheduled plant shutdown.”

Poland: Italy-based Bedeschi has won a contract with China-based Nanjing Kisen International Engineering, part of China National Building Materials, to carry out equipment supply for the modernisation of crushing and storage facilities at a Lafarge Polska cement plant in Poland. The supplier says that it will provide a crushing system featuring two RI 450/15000 double rollers and two Pal SP 130/18 portal reclaimers for raw materials storage.

Thailand: Germany-based Beumer has replaced the belt of a 3.5km raw materials conveying system at TPI Polene’s cement plant. It used a process that allows the new belt to be inserted into the system and the old belt to be pulled out only in one go, instead of exchanging the single belt sections one after other. The supplier says that this resulted in ‘substantial’ time saving for the customer and avoided unplanned system failures.

Beumer originally commissioned the conveying system in 2015. The 2200t/hr system consists of two regenerative belt conveyors with system control, transfer stations and filter systems, as well as foreign material separators. 989m of further belt conveying systems are used to remove the material from the blending bed and to feed the primary hopper of the raw mills complete the system. Installation took 11 months, followed by a three-month commissioning period.

Pakistan: Maple Leaf Cement has commenced operations at clinker line 3 of its Iskanerabad cement plant following a modification to increase capacity. The Dawn newspaper has reported that the plant now has a capacity of 18,500t/day of grey clinker, up by 3% from 18,000t/day previously.

Poland: Lafarge Poland, part of Switzerland-based LafargeHolcim, has begun the demolition of part of its 2.0Mt/yr Małogoszcz cement plant in Świętokrzyskie voivodeship. The work proceeded with the company taking down one of the plant’s 120m-high chimneys.

Industrial director Stanislaw Sobczyk said that the new Małogoszcz cement plant would “rise like a Phoenix from the ashes” of the old. The plant’s two chimneys were a local landmark and appeared on the logo of the former Małogoszcz Cement Company.

India: Prism Cement has established a 12MW waste heat recovery (WHR) plant and 10MW solar power plant at its 6.1Mt/yr-capacity integrated Prism cement plant in Satna, Madhya Pradesh. The plant’s total WHR capacity now totals 22MW, with a total of 23MW solar power capacity. The measures are part of the producer’s sustainability initiatives, by which it aims to reduce its reliance on non-renewables.

Russia: SibCem subsidiary Angarskcement has replaced air ducts with local air blowers in its raw materials and clinker grinding units. The producer made the modification to the units’ three horizontal slurry tanks.

Managing director Dmitry Kireev said, “The programme to reduce the consumption of compressed air in the slurry section of the raw materials and clinker grinding facility will continue.” He added, “It is important for us to reduce the costs of energy resources consumed by slurry basins, since they directly affect the cost of the products manufactured by the plant.”

Spain: The Málaga government has approved adjustments to HeidelbergCement subsidiary FYM’s special plan for its La Araña cement plant. The La Opinión de Málaga newspaper has reported that the plan incorporates the findings of new environmental and landscape studies enabling an enlargement of the area of operations. The approval’s effect will depend on the outcome of an on-going court case by a local interest group against the plan.

India: Dalmia Bharat subsidiary Dalmia Cement has commenced commercial production of cement at the new 2.3Mt/yr production line of its Bengal Cement Works cement plant in Midnapore, West Bengal. The new line brings the plant’s total capacity to 4Mt/yr.

Chief operating officer Ujjwal Batria said, “To ensure that demand is met in a sustainable manner, we have deployed the latest machinery and technology at our Bengal Cement Works unit and will be aiming to produce 100% blended cement. This step is also in line with our commitment to become carbon negative by 2040.” He added, “Post the lockdown-led demand disruption, the cement sector has been continuously witnessing buoyancy across the country. This is largely led by revival in demand from the infrastructure and urban housing sectors, along with the demand from individual homebuilders and the government's rural housing schemes especially from east and central regions. Hence, the onset of commercial production at the Bengal Cement Works unit will enhance our ability to contribute towards nation building and Atmanirbhar Bharat, while also catering to the growing demand from the eastern and north-eastern states of the country.”

Guatemala: Mexico-based Cemex subsidiary Cemex Latam Holdings plans to install a new 1000t/day horizontal ball mill and support infrastructure including a dust collector and 3000t silo at its Puerto de San José grinding plant in Escuintia. Central America Data has reported the value of the work as US$16m.
