Hydrogen injection, co-processing and low carbon cement
At Cementos Argos we understand the call to contribute to mitigating the effects of climate change by reducing CO2 emissions in our production processes and developing new and better products and solutions.
We have successfully increased kiln output and reduced emissions through a hydrogen injection trial in Honduras. Key points:
- Hydrogen Success: Injecting hydrogen into the kiln’s main burner improved productivity and reduced CO2 emissions.
- Positive Outcomes: The trial achieved a 3% kiln productivity increase and 2% reduction in energy consumption. It’s financially feasible with a $5.5 million net present value (NPV) and 204% internal rate of return (IRR).
With the co-processing in our Cartagena plan we have achieved a certification for around 20,000 carbon bonds, marking it one of Colombia’s first industrial sector emission reduction projects. We used diverse waste sources and plan to expand, expecting over 30 tons of annual emission reductions.
In Argos North America, we are reducing our carbon footprint by adopting Portland Limestone Cement (EcoStrong PLC) in place of traditional cement. This transition lowered CO2 emissions significantly by reducing of clinker cement factor from 89% in 2021 to 80% in 2022. PLC is more environmentally friendly and improves production capacity and sales margins.
