Organic Building Materials Division was established in 1989 with the responsibilities of generating, cultivating and promoting the latest developments through research and developments in the field of alternative sustainable building materials and composites for building applications using agro-industrial wastes, protective and decorative coatings, sealants, roofing materials etc. It is also putting its endeavor in the enhancement of interaction with building and construction industry for variety of activities on different organic building products. The Division has adequate expertise along with state-of-art infrastructuree for undertaking research and development programs on its own as well as on sponsorship basis in all the related areas of work.  The Division is also working in the development of materials and techniques needed for the repair, retrofitting and protection of structures.

R&D Areas

  • Alternatives to wood and to other building products and process development.
  • Value added products and process development
  • Recycling of plastic waste for building applications through through value added products development
  • Agro-industrial waste utilization
  • Protective and decorative coatings and finishes
  • Sealants, adhesives and water proofing systems for building applications
