lnstitute of Radiation and Polymer Technology

Phone: 88-02-7789343

INTRODUCTION:

Institute of Radiation and Polymer Technology (IRPT) is dedicated to research and development activities by the application of radiation technology. The institute was established in 2010 and has been able, through innovative research and technological achievements in polymer science and industrial application of gamma radiation sterilization process to contribute to the national effort for achieving economic self sufficiency. The institute has the 350 kCi Co-60 gamma source which is the largest source in Bangladesh.

AIMS AND OBJECTIVES:

aims and objectives of the institute are:

  1. To carry out research for the development of different composite polymeric substances for the commercial production of goods for household use.
  2. To develop and improve radiation processing technology and to transfer the technology to interested companies for industrial application and
  3. To apply gamma irradiation for microbiological quality improvement of medical products, pharmaceutical raw materials, and for the preservation of food grains, spices etc.

ACTIVITIES:

a) Research & Development:

  1. Development of composite polymer for household application: Radiation technique is used to increase tensile strength, bending strength, impact strength, and durability of different composite polymer. Jute fiber, glass fiber, cotton fiber and different natural fiber are used in the research of development of new composite polymer.
  2. Extraction of natural polymer and application: Sodium alginate is extracted from sea weed for use as stabilizer, emulsifier and also as fertilizer. Chitosan is extracted from prawn shell and effect of gamma radiation on chitosan was determined. Radio-sterilized chitosan, gelatin etc. are used in tissue engineering.
  3. Detoxification of Textile Effluent by Gamma Radiation and Application as Liquid Fertilizer on different Plant: Textile effluent was irradiated and its quality was improved by decreasing its BOD, COD, TDS, TSS level and applied to different plant e.g. Radish (Raphanus sativus), carrot, chilli(Capsicum frutescens), Malabar spinach(Basella alba) etc. as fertilizer. Very promising results were found.
  4. Development of Artificial blood plasma expander: Artificial blood plasma expander has been prepared. When blood loss exceeds not more than 30%, blood plasma expander can work as an alternative to total blood infusion
  5. Development of Dye Sensitized Solar Cell by locally Available Natural Dye: Dye sensitized solar cell using naturally available dyes and polymers has been developed.
  6. Low cost Proton Exchange Membrane for fuel cell has been prepared: Linear low density polyethylene (LLDPE) based PEM has been prepared. Radiation grafting technique has been applied to introduce the styrene monomer onto the LLDPE films by UV radiation under atmospheric circumstances.

b) Services:

The Co-60 gamma irradiation plant started its operation during the fiscal year 2009-2010. Irradiation service has been providing to private companies for commercial purpose giving assurance of complete sterilization of products or deliver dose as per company demand. Irradiated items are Powder/whole spices, pharmaceutical ingredients, capsule shell, syringe, peat soil, cotton absorber etc. Since establishment total 61,32,331 BD Taka was earned as revenue from this source by 30 April, 2014.

SUCCESSES ACHIEVED:

For innovative research and development in IRPT, Dr. Mubarak Ahmad Khan, CSO & Director of IRPT received the BAS Gold Medal Award for senior Scientist in Physical Sciences for the year 2010. A brief account of the achievements of the institute in R & D activities with specific areas of applications of the research findings are given below:

  1. Invention of Jute reinforced polymer composite "Jutin": Jute fiber (hessian cloth) reinforced unsaturated polyester (USP) resin composite was prepared by simple hand lay-up technique. The product showed 147MPa tensile strength, 150MPa bending strength, 68 kJm-2 impact strength and more than 50 years durability. Many value added products like roof tiles, room insulator, shading, kitchen fittings, fencing, door shatter, chair, table and other furniture, helmet etc. were also prepared using the same technology. Many of the products were successfully delivered to the end users where very positive feedbacks were found. The eye catching successes of field trials have caught attention of several entrepreneurs who are very interested to commercialize the products. So, this jute based composite is very promising as an alternative of commonly used construction materials in rural area of developing countries as well as for preparing value added products for household purposes.

  2. Invention of Gamma Radiation Sterilized Chitosan Coated Surgical Gauge for Use in Wounds Dressing: Porus scaffold composite films were prepared and characterized by blending chitosan and gelatin solution for tissue engineering. Gelatin–chitosan ratios of 10: 3 was used to prepare scaffold composite. In vivo testing was done in a Wistar rat (Rattus norvegicus) model and the healing efficiencies showed 100% healing, where the commercial conventional dressing showed only 40% of healing in the same period. Different companies are interested to commercialize this product named “Eco Heal”.
