Bamburi Cement has announced that it will cease production of Ordinary Portland Cement (OPC) within its product line from January 1, 2024.
This is part of its commitment to decarbonising its operations and providing a greener option of building materials.
The commitment, comes amid the ongoing 2023 United Nations Framework Convention on Climate Change (COP28) in United Arab Emirates, accelerating the company's sustainability target to 100 per cent green products by 2025, and decreasing carbon (CO2) emissions to fight climate change.
Bamburi Cement Group managing director Mohit Kapoor said it will affect the production of Powerplus cement, used in medium to large construction projects but will have no disruptive impact on customers due to presence of alternative greener products.
“Withdrawing OPC from the construction sector is critical to greening and decarbonising the industry. In combination with the thrust on the use of eco-friendly cement offerings, it gives us the opportunity to onboard our partners and customers in our journey to net-zero,” said Kapoor.
As an alternative and in mitigation to the OPC, the company has a range of eco-labelled cement products which assure better quality and durable construction output with low carbon emissions, according to the company’s head of innovation and technical services, Fidelis Sakwa, said.
"Our flagship eco-labelled product Bamburi Duracem 42.5 cement reduces carbon emissions by 64n per cent in comparison to the OPC. Duracem was successfully used to build the Makupa Bridge in Mombasa resulting in a saving of 10 million kgs of CO2 as compared to OPC that would have been used," said Sakwa.
He added that Bamburi Cement’s technical team has invited contractors for consultative opportunities on providing viable options, including conducting project specific concrete mix designs with a lower carbon footprint in the near term.
OPC has been used traditionally for large infrastructure projects and high rise buildings.
OPC typically contains 95 percent clinker, an intermediate material in the manufacture of cement produced by burning limestone and other materials in a kiln where CO2 is invariably released in the process.
OPC emits the highest greenhouse gases into the atmosphere during its manufacturing and production.
One ton of clinker emits around 0.83 tons of CO2 into the atmosphere according to Global Cement and Concrete Association (GCCA) regional data, whereas one ton of OPC emits approximately 0.79 tons of CO2, driving the building industry’s eight per cent (2.8 billion tons) of carbon emissions globally.
The announcement reinforces the company’s progress made so far in transitioning to low-carbon cement.
In November last year, Bamburi Cement eco-labeled its four cement brands to represent 30 per cent lower CO2 emissions compared to pure Ordinary Portland Cement.
The four include Bamburi Duracem, Bamburi Fundi, Bamburi Tembo, and Bamburi Nguvu.
Last year, Bamburi Cement reduced its consumption of fossil fuels to power its cement kilns, which generate clinker, by 5.5 per cent by co-processing nearly 75,000 tons of waste.
Further, it has increased the use of alternative raw materials in cement production such as pozzolana, limestone, slag, and gypsum to reduce the clinker factor.
