Explore how green retrofitting of factories in India is transforming industrial sustainability through energy efficiency, renewables, and eco-friendly upgrades.
🏭 What is Green Retrofitting of Factories in India?
Green retrofitting in India refers to the process of upgrading existing factory infrastructure with sustainable, energy-efficient, and environmentally friendly technologies. Unlike new greenfield projects, retrofitting focuses on modernizing old industrial buildings, machinery, and processes to reduce their carbon footprint—without halting operations.
🇮🇳 Why India Needs Factory Retrofitting
India is home to over 2.5 lakh registered factories, many of which are decades old and highly energy-intensive. These factories contribute significantly to:
- Industrial air pollution
- Carbon emissions
- Water wastage and inefficient cooling
- High operational costs due to outdated systems
With India targeting Net Zero by 2070, green retrofitting of factories in India is a low-hanging fruit with enormous potential.
