A newly implemented “Green Pretreatment” configuration in the Pretreatment Electrodeposition (PT‑ED) line applies an ambient‑temperature phosphate process to lower energy demand, simplify operations, and reduce annual carbon emissions at scale.
JSW MG Motor India has introduced a Green Pretreatment line in its shop-floor pretreatment stage—reported as an industry first for an OEM—implemented in partnership with PPG Asian Paints and associated with an estimated reduction of ~1,800 tons of carbon emissions per year.
The core process change is the deployment of an ambient‑temperature phosphate chemistry (noted at ~38°C) in the Pretreatment Electrodeposition (PT‑ED) line, replacing conventional operating regimes typically reported in the ~42–50°C range.
By lowering the thermal setpoint, the approach is framed as eliminating (or substantially reducing) the need for heating during pretreatment, with downstream effects that include fuel savings and reduced direct/indirect carbon emissions.
In operational terms, the initiative is also positioned as improving process efficiency through simplification of steps and a reduction in maintenance requirements, thereby coupling sustainability outcomes with manufacturing reliability and throughput stability.

Engineering Logic of the “Green Pretreatment” Intervention 

The pretreatment stage precedes electrodeposition and is typically energy intensive when heating is used to maintain elevated bath temperatures; the reported shift to an ambient‑temperature phosphate process (38°C) reduces this dependency and therefore the energy input required per unit processed.
Relative to the previously cited conventional window (42–50°C), the lower setpoint implies reduced fuel consumption and correspondingly lower emissions, with the article attributing an annualised abatement magnitude of approximately 1,800 tons of carbon emissions.
Additionally, the initiative is explicitly framed as improving process efficiency by simplifying operations and reducing maintenance, suggesting that the sustainability intervention is not isolated from productivity objectives but is treated as a process‑improvement programme.
