A model of industrial synergy emerges between Patratu Thermal Power Station (PTPS) renamed as Patratu Vidhyut Utpadan Nigam Limited (PVUNL) and UltraTech Cement’s Patratu unit known as the Patratu Cement Works. This partnership showcases how sustainable collaboration can transform waste into value while reducing environmental burden.
Patratu Thermal Power Station generates large volumes of coal ash as a by-product of electricity production. About 80 percent of this ash is fine fly ash collected in dry form from flue gases using electrostatic precipitators, while the remaining 20 percent is bottom ash handled through wet disposal systems. The collected dry fly ash is stored in silos and made available to industries under regulated supply programs.
UltraTech Cement (Patratu Cement Works) stands as a major beneficiary and partner in this cycle. The plant utilizes the fly ash as a key substitute material in manufacturing blended cements like Portland Pozzolana Cement (PPC) and Portland Composite Cement (PCC). By sourcing fly ash locally from PVUNL, the UltraTech reduces its dependence on virgin raw materials and minimizes carbon emissions associated with clinker production.
This relationship not only optimizes resource use but also mitigates the environmental challenges of ash disposal. Fly ash is transported in closed tankers to maintain air quality and comply with regulatory norms. Together, PVUNL and UltraTech Cement demonstrate how industrial collaboration can foster cleaner production, and a shared path toward sustainability.
