Resource efficiency can be achieved using the earth’s limited resources sustainably while minimizing environmental impact.

India is the second-largest producer of bricks in the world after China. The hand-moulded brick industry uses a massive amount of topsoil as crude material which could have been utilized for developing vegetation instead. It is additionally a significant cause of local air pollution because of emission CO, SO2, and HF during production.

Few of the recognized REBs are perforated bricks, hollow blocks, fly ash bricks, Autoclaved Aerated Concrete (AAC) blocks, Cellular Lightweight Concrete (CLC), Construction and Demolition (C&D) waste Bricks, and Compressed stabilized Earth Blocks (CSEB)



  • Reduction of raw materials required as they are hollow and use industrial waste.
  • Low greenhouse gas emissions during production.
  • Low vitality utilization.
  • These blocks have low thermal conductivities which reduce the energy consumption of HVAC.
  • Lightweight reduces the dead load of the building.
  • Favouring government policies.


  • Industrial wastes which are raw materials of AAC blocks are not available in all parts of the country.
  • Maintenances.
  • High Cost of installation of machinery for production.
  • The cost of blocks is higher than conventional bricks.

We at Swasti Project have extensively used Weinerberger Porotherm smart bricks in our projects, and it has helped us in taking a stride towards sustainable construction practices. The lightweight property of the blocks has helped in reducing steel consumption in the structure and has speeded up the block work process as shifting and working with lightweight blocks is simpler. Adding to it, thermal and sound insulation is much better than conventional bricks.
