A kiln for cement production typically uses coal as a fuel to heat a mixture of raw materials at 1450°C, transforming the chemical and physical components to form a new substance called a clinker a gray pebblelike material consisting of special compounds that give cement its characteristic binding properties.

Baghouse Wikipedia

A baghouse, also known as a baghouse filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants.

CO2 Capture from Cement Plants and Steel Mills Using Membranes

Carbon dioxide capture, utilization, and storage (CCUS) has been identified as an effective method of mitigating anthropogenic CO2 emissions. To date, most research and development has centered on capturing CO2 emitted from coal power plants, as they are the largest point source emitters globally.
