Dr. Morepen Laboratories Ltd. Achieves 33% Cost Savings Through Diesel to LPG Conversion with Pune Gas

Executive Summary

Dr. Morepen Laboratories Ltd. operates large-scale pharmaceutical manufacturing facilities where uninterrupted energy supply is critical to production efficiency and compliance standards. The plant was previously dependent on diesel for process heating, resulting in high fuel expenditure and carbon-intensive operations.

Pune Gas implemented a structured diesel-to-LPG conversion strategy tailored to the plant’s operational load requirements. The transition delivered significant cost savings, improved combustion efficiency, and enhanced sustainability, without disrupting production.

Before (Diesel-Based Heating)

  • Diesel consumption: 10,000 litres per month 
  • Monthly fuel cost: ₹8.7 Lakhs 
  • Lower combustion efficiency with higher emissions 
  • Increased maintenance due to soot and residue formation 

After (LPG System by Pune Gas)

  • Monthly savings: ₹3.5 Lakhs 
  • Annual savings: ₹42 Lakhs 
  • Cost reduction achieved: 33% 
  • Cleaner combustion with reduced maintenance 
  • Improved energy efficiency and operational stability

Client Overview

Dr. Morepen Laboratories Ltd. is a leading pharmaceutical manufacturer with a strong focus on operational excellence, compliance, and cost optimisation. Energy reliability is critical to maintaining production consistency, process precision, and stringent quality standards across its facilities

The Challenge

The facility’s dependence on diesel created multiple operational and financial constraints:

  • High and fluctuating monthly fuel expenditure 
  • Lower combustion efficiency compared to LPG 
  • Increased maintenance due to soot and residue buildup 
  • Higher carbon footprint 
  • Limited awareness among channel partners regarding LPG advantages 

While diesel ensured continuity, the cost-to-efficiency ratio was no longer optimal.

The Solution

Pune Gas conducted a detailed technical and financial feasibility assessment before designing a customised LPG conversion plan aligned with process requirements.

The solution delivered:

  • Complete load assessment and energy mapping 
  • Engineered LPG system integration with existing infrastructure 
  • Controlled and stable heat output 
  • Compliance-aligned safety systems 
  • Seamless transition ensuring zero production disruption 

Operational Impact

  • Cost Optimisation: ₹3.5 Lakhs monthly savings achieved 
  • Efficiency Improvement: Higher combustion efficiency with stable heat output 
  • Maintenance Reduction: Elimination of soot and reduced servicing needs 
  • Sustainability Gains: Lower emissions and cleaner operations 

Production Continuity: No disruption during or after transition

Execution

The project was executed through structured coordination between the Pune Gas technical team and the plant operations team. Design, installation, safety checks, and commissioning were completed with minimal interruption, ensuring a smooth and controlled transition.

Additionally, awareness gaps among channel partners were identified, highlighting the importance of structured LPG education in accelerating industrial energy transformation.

Conclusion

By transitioning from diesel to LPG, Dr. Morepen Laboratories Ltd. successfully optimised its fuel infrastructure for both cost efficiency and sustainability.

The project delivered measurable financial savings, improved operational performance, and reinforced the strategic value of cleaner energy adoption in pharmaceutical manufacturing.
