Study on the identification and evaluation of technologies and industrial processes used in cement producing industries in Congo



The Republic of Congo has conducted its’ Third National Communication (TNC) and is currently in the process of finalizing its’ new Nationally Determined Contribution (NDC) to be submitted to the UNFCCC. In the TNC, the GHG for the industrial process and product use sector (IPPU) were estimated on a basic level. However, in order to be more precise and to make informed decisions in order to reduce GHG emissions, more detailed analyses of the technologies, processes and products used in the cement industry (a key industry within IPPU) are necessary. Currently, the Republic of Congo has 5 cement plants with a total production capacity of 3.200.000 tons/year. This amount was drastically increased since 2014, as the former production in 2 cement plants was not sufficient for the increasing consumption in Congo Brazzaville. Back in 2014, CO2e emissions from the cement industry reached 93,3323 Gg, which has yet strongly increased with the growing production.

CTCN Support

•    General audit of technologies, processes and materials of the cement plants;
•    Detailed energy audit of selected cement plants;
•    Identification of activity data (AD) and emission factors (EF);
•    Development of audit and management protocols and monitoring;
•    Identification of technologies and processes for a more efficient and sustainable cement industry.

Expected Impact

•    Higher precision in emissions reporting and monitoring;
•    Reduction of GHG emissions through implementation of technologies and processes that increase efficiency and sustainability in cement industry.
