Green Power. Safe Recovery. Net Zero Bangladesh.
EngineerBari™ National Initiative for Responsible SF₆ Management and Environmental Protection
Problem: SF₆ Gas Emissions
Current Situation in Bangladesh
✅ SF₆ gas is widely used in 132–400 kV GIS substations
✅During maintenance, repair, or replacement:
✅Gas is often vented or partially handled
✅No certified recycling facility exists. SF ₆
✅Global Warming Potential = 23,500× CO₂
✅ Atmospheric life = 3,200 years
Impact
✅Environmental damage
✅Future regulatory risk
✅Foreign currency loss (imported gas)
✅ Unsafe working practices
✅ The problem is real, growing, and unavoidable

Action: SF₆ Gas Recovery, Recycling & Engineering Control
Our Action
✅ Establish Bangladesh’s first SF₆ Gas Recovery & Recycling Plant
What We Do
✅Recover SF₆ gas from GIS & circuit breakers
✅Purify & recycle contaminated gas
✅Re-certify gas to IEC standards
✅ Re-supply gas locally
✅ Safely destroy unusable gas
What This Achieves
✅Prevents greenhouse gas emissions
✅ Saves import cost
✅Creates green engineering jobs
✅Makes Bangladesh climate-compliant
Future: Sustainable & Eco-Friendly Power Systems
Engineers play a critical role in reducing SF₆ emissions through professional gas management practices:
Key Engineering Actions:
✅SF₆ gas recovery from GIS and circuit breakers during maintenance
✅Gas recycling & purification to IEC standards
✅Leak detection & repair (LDAR) using SF₆ detectors
✅Gas quality testing (Moisture, SO₂, purity)
✅Safe gas handling & storage in certified cylinders
✅Training & SOP implementation for site engineers
Benefits:
✅Prevents direct gas release into the atmosphere
✅Extends equipment life
✅Reduces operating cost
✅Ensures environmental compliance
✅ Recovered SF₆ can be reused safely instead of being destroyed or released.
