In an On-site Plant, PCC (Precipitated Calcium Carbonate) is produced in a satellite facility; onsite or close to a paper mill and the resultant slurry is pumped directly to the mill. In this arrangement, all plant and equipment required for producing PCC are installed under lease agreement in the premises of its end user. The utilities like Power, Water, Steam and the CO2 from the boiler stake (going into the air after ESP) are used to make PCC in slurry form for its use in paper application. This unique environment friendly technology not only reduces the energy consumption and drying time but also utilizes the CO2 emitted from the boilers.
