Snapshot

• Why Eastern UP & Bihar are emerging:
  The eastern Uttar Pradesh and Bihar region is becoming a key fly ash brick and block manufacturing hub, leveraging abundant fly ash from NTPC and private thermal power plants along the Ganga basin.
  With increasing government mandates for fly ash utilization, these clusters are growing rapidly, supplying construction-grade bricks, hollow blocks, and pavers to real estate, infrastructure, and rural housing projects.
  Supported by state industrial policies, MSMEs, and Make in India initiatives, this cluster is a major player in green construction materials.
  
• Global Positioning:
  While still largely domestic market-focused, these clusters represent India’s sustainability push, attracting interest from global development agencies (World Bank, UN-Habitat) for climate-friendly housing projects.
