Bangladesh is the 4th largest producer of Rice in the world with an approximate yearly production of 50+ million MT. The majority of the final product is par-boiled rice, the process involves steaming. Annual Rice Husk production is about 10 million tonnes in Bangladesh. Thus Bangladesh produces a huge amount of rice husk ash and more than 80% of it finds no use and needs disposal. Such disposals are causing major Environmental hazards for the Country. Every MT of Rice Paddy produces about 40Kg of RHA thus causing total production of around 2M MT of RHA every year in Bangladesh. It is a unique opportunity for Bangladesh to use agricultural waste to produce Sodium Silicate instead of burning sand with costly natural gas. Save nature and go for Green.

7. UNIQUE
PROPOSITION
UNIQUE PROPOSITION
• The Rice Husk Ash is first digested in Caustic Soda to
produce Sodium Silicate Liquid. The quality of Sodium Silicate
must be excellent for excellent quality of final product.
Sodium Silicate Production from Ash & Caustic Soda
2NaOH + SiO2 = Na2SiO3 + H2O
• (Only SiO2 of Ash contributes to reaction. Na2SiO3 is Sodium
Silicate, this also is shown as Na2O,nSiO2 where no. of SiO2
modules can change depending upon quality of material).
• Caustic Soda is 100 % locally produced and price is
deceased by more than 40 % in last 5 Years.

8. UNIQUE PROPOSITIONS
1. No Natural Gas Required
2. No Imported Raw Material
3. Saving Foreign Currency
4. ZERO impurities , Purest form of product
5. Cost Saving and high Profitability ( High Turn Over/Profit )
6. Sustainable & Energy Efficient
7. ZERO Carbon Footprint
Reference:
The BERC last raised the gas tariffs by 32.8 per cent on average with effect from July 1,
2019, marking the biggest-ever hike so far.
Natural gas tariffs for small and cottage industries under commercial sector were kept
unchanged at Tk 17.04 per cubic meter last time.
Captive power plants counted a tariff hike by 43.97 per cent during the last hike to Tk
13.85 per cubic meter from previous Tk 9.62.

9. RICE HUSK

10. RAW MATERIAL- AVAILABILITY
• Bangladesh is the 4th largest producer of Rice in the world with
approximate yearly production of 50+ million MT. ( Ref: FAO)
• Majority of the final product being par-boiled rice, the process involves
steaming.
• Annual Rice Husk production is about 12 million tones in Bangladesh.
• Thus Bangladesh produces huge amount of rice husk ash and more
than 80% of it finds no use and needs disposal. Such disposals are
causing major Environmental hazards for the Country.
• Every kg of Husk produces 25 % of RHA. So, the Production of RHA is
3 MT/Year in Bangladesh
