Prologue

I’m running the Summary of Department of Science and Technology (DST)’s Annual Report 2012-13. This report contains some good material UPSC General Studies Mains Paper 3 Topics:

  1. Science and Technology- developments and their applications and effects in everyday life
  2. Achievements of Indians in science & technology; indigenization of technology and developing new technology.

Total four part article series:

  1. Agro, EnB, Solar and Water (We’re here)
  2. Medical/Healthcare, Building-construction, textile, metal, plasma, Nano etc.
  3. Projects for benefit of SC, ST, Women, States and Human resource development
  4. Mapping, International relation (IR), awareness campaigns and awards.

ok But What about the Hindu science tech compilation for Sep-Oct-Nov? I’ll release it after 15th Nov.

Agri / Dairy related

Potash from Sea Water

  • Potassium is an essential plant nutrient. MOP (Muriate of Potash) and SOP (Sulphate of Potash) are the popular forms of potassic fertilizer,
  • but We don’t have local mineral resources, have to rely on Potash through imports= more current account deficit
  • However, we’re blessed with long coast line=salt production.
  • Britten= bitter liquid remaining after common salt has been crystallized out of sea water.
  • This Britten can be used to harvest potassium chloride (20-25 gms per liter)=> further processing will give Potash.
  • DST funding project for this indigenous production of Potash.
  • + another project to extract ultra-pure magnesia from seawater

Banana Stem for Paper Making

  • India being the largest producer of banana in the world
  • But Banana stem=generally discarded as waste.
  • banana stem+wheat straw / Bagasses=>pulp them = can be used for paper making and reinforcement fibres
  • this will reduce the need to import softwood/hardwood pulp.

Non-Edible Oils (NEO)

  • Example of Non-Edible oils= Wild Apricot, Karanj, Malkangni, Jojoba, Wild Castor
  • NEO can be used for making soaps, lubricants, paints and varnishes, medicines etc.
  • But all value-addition and employment generation takes place in urban-industrial areas.
  • And tribals get very low income for collecting raw material.
  • DST promoting a hub-and-spoke supply chain using Village level women SHG.

let’s check some more projects supported by DST:

Assassin bugs

bio control agents= using bugs/living organism to destroy other pests. DST running project to see bio control potential of

  • copepods against mosquito larvae

  • but fly ash could also be used for
    • Construction of railway embankments
    • in concrete for critical structures such as building
    • foundation material for turbo- generators, chimneys and cooling towers etc. in power plants
  • DST promotes R&D for such uses of fly ash to change the image of fly ash from a “WASTE MATERIAL” to a “RESOURCE MATERIAL”.
  • Since its inception, this project has added economic returns worth >3 billion USD and employment >1 million people.
  • Even Russia has sought the expertise of this fly Ash Unit.

Bamboo Mission
