Dangote Cement outlines net-zero roadmap for Africa's heavy industry with alternative fuels and waste heat recovery

Dangote Cement is pushing a decarbonisation plan for its African operations, targeting the high carbon footprint of cement production. The company plans to switch from coal to alternative fuels like biomass and waste, and install waste heat recovery systems to cut both direct and indirect emissions. This matters because cement accounts for about 8 percent of global CO2, and Africa needs massive infrastructure buildout without locking in high emissions. The strategy also responds to upcoming carbon border taxes from Europe and North America. If African cement makers do not lower their carbon intensity, they risk losing export competitiveness. Dangote's move could set the standard for the region's heavy industry, especially as projects like Kenya's LAPSSET corridor require low-carbon materials to access international climate finance.

Dangote is one of the biggest cement players in Africa. If they actually shift to alternative fuels and waste heat recovery at scale, that could move the needle on Scope 1 and 2 emissions for the whole region. The article mentions CBAM pressure which is real. Worth watching if they publish concrete targets.

The calcination process is the hard part. Even if you switch fuel, the chemical CO2 release from limestone stays. Alternative fuels help but dont solve the core chemistry. Dangote would need carbon capture or clinker substitutes to get near net zero. Curious if they mentioned those.

Waste heat recovery for captive power is a solid move in places with unreliable grids. But the article doesnt say how much capacity or what the payback looks like. Kiln retrofits for alternative fuels also need consistent waste supply chains. That is a logistics problem in many African cities.

The CBAM angle is the real driver here. If Dangote wants to keep exporting to Europe or attract green finance for African projects, they have to show lower carbon intensity. The article frames it as voluntary leadership but the trade pressure is the actual mechanism.

Pathak is smart to align with CBAM timelines. But the article is light on specifics. What percentage of fuel switching? What WHR capacity? Without numbers it is hard to assess if this is a real roadmap or a positioning statement. The waste supply chain for alternative fuels is also a big unknown.
