Common Fund for Commodities (CFC) funded Project

Study in the Residual Silica/Silicate in Raw Jute and Scope for Elimination/ Reduction (CFC/IJSG/23FT)

  Total Cost: USD 45,000
  Fund : CFC  Grant : USD 34.000

October 2005-Dec. 2007

  Background: The European pulp producers expressed concern on the presence of higher level of Silica in raw jute because of the stringent quality reqrds in the  European/developed countries. Silica content above in min. allowed level (0.02%) would make the pulp unfit for making special insulation paper since this tends to  increase the conductivity of these papers to an unacceptable level.
  Participating Countries:


Inst. of Jute Technology (IJT)



Bangladesh  Jute Res. Institute (BJRI)

  Summery of findings and outcome
  • The study has revealed and confirmed that the intrinsic silica content in jute is very negligible. That jute sometimes containing silica above acceptable limit of 0.02% is mainly due to external contamination.

  • This is again possible to be reduced by simple washing and a simple sequence of chemical treatments which has been described in the PCR.

  • A Protocol on ‘Making Jute Free from Silica Contamination’ was printed in three languages i.e. English, Bangla and Hindi.



Commercialization/ Current Status:

The PCR along with the Protocol on ‘Making Jute Free from Silica Contamination’ have been distributed to all Members, raw jute traders/ importers and relevant Associations / Associate Members for dissemination of the information generated through this study and eliminate misgivings about raw jute.
