  Investment Cost:
   
  The investment costs for the smallest commercially viable production unit is estimated to be INR 41,260,000, (= USD 745,801.46) yielding an annual production of 360 ton jute-PP composite granules.
   
   
  Project Summary:
   
 

Duration:

02 August 2004 - 31 December 2008

Total Project Cost:

USD 441,000

Project Executing Agency (PEA):

Agrotechnology & Food Innovations B.V. (AFSG)

Wageningen, The Netherlands

Project Supervisory Body:

International Jute Study Group (IJSG)

Project Partners :

Aziz Pipes Ltd., Dhaka Bangladesh

Birla Corporation Ltd., West Bengal, India

   
   
  The broad objectives met in the project:
   
 

The applied research for optimization of jute-polypropylene (PP) materials, meeting requirements of moulding industry in India and Bangladesh.

Production of pilot scale amounts of jute-PP granules and moulding of these using industrial equipments in India and Bangladesh.

To carry out an evaluation/impact assessment and needs assessment for jute reinforced-PP market development.

   
   
  Major Outcomes:
   
 
  • One of the most important results of the project was the development of jute reinforced polypropylene (PP) granules as intermediate material for the production of various end-products to replace glass fibre (GF) reinforced PP. The developed material was found suitable to be used to produce the products e.g.,

Free flowing jute-PP granules in pilot scale quantity

Automotive industry (door panels, dash boards, instrument panels, door trims, sash, brackets, pillar trims etc),

Packaging (inlands and export of agricultural products e.g., crates, inlays for crates, pallets, boxes and cases) and

Construction, housing, interiors (panels, beadings, chair, head rest, curtain rods, blind channels, lighting brackets, fixtures, etc.)

Consumer product (housing for computer screens, refrigerators etc.).

  • The results show that injection moulding on regular industrial moulding equipments in India and Bangladesh is very well possible.

  • The advantage of jute-PP is that the strength is twice and the stiffness is 3-4 times that of unfilled PP.

  • The stiffness performance of jute-PP is similar to that of glass fibre-PP composite materials, which makes them highly competitive in engineered products.

  • Less jute-PP material will be required to meet strength and stiffness requirements in products.

  • Addition of pigments enables any colour, except bright colours, is no loss of strength performance.

  • Jute-PP granules can be produced at cost very similar to pure PP granule costs, or even at a lower price, while providing a far better performance.

   
  Economic evaluation of the production and price comparison with competing products:
   
 

The investment costs for the smallest commercially viable production unit is estimated to be INR 41,260,000, (= USD 745,801.46) yielding an annual production of 360 ton jute-PP composite granules. At lower nominal extrusion capacity, the investment costs and the labour costs will contribute disproportionately to the production costs. Assuming a throughput of 50% of the nominal extrusion capacity, the costs of jute-PP granules (INR 89/kg) will be on the same level as the costs for pure PP (INR 90/kg), however, providing a higher strength (89 Vs 43 MPa), stiffness (5.4 Vs 1.3 GPa) and HDT (115 Vs 60C) than pure PP. On a performance/price basis, jute-PP can also compete very well with glass fibre reinforced PP and talcum filled PP.
