Chemistry Division
1. Introduction
Chemistry Division is one of the important division of the Technology Wing of the Bangladesh Jute Research Institute. The research activities of this Division are said to be the basis of the research work of the technical wing. Determining the physical and chemical properties of jute and homogeneous jutefibers is one of the daily tasks of this Division. Chemistry Division conducts various basic researches on that results play a helpful role in making progress of others division’s research. Many eminent scientists of the country worked in Chemistry Division . At present Dr. Md. Nurul Islam is the head of division, and other scientists are also involved in research activities of the division.
2. The objectives of Chemistry Division
There are a total of 2 departments under the Division of Chemistry-
1. Fiber Chemistry Department
2. Department of Industrial Chemistry.
The purpose of the branches is discussed below:
Objectives of fiber chemistry
1. In order to ensure proper and versatile use of jute, physical and chemical properties of jute and homogeneous fiber crops are determined in this department .
2. To improve the quality of jute fiber through various chemical treatments including analysis of jute fiber under this department.
3. To make microcrystalline cellulose (MCC) by making cellulose from jute for the purpose of making medicine base material.
4. Cellulose derivatives such as: carboxy methyl cellulose (CMC), cellulose acetate, etc. to create opportunities for use in various fields as pharmaceutical companies and also as viscose material.
5. Making jute batching emulsion with vegetable oil instead of mineral oil.
Objectives of Industrial Chemistry
1. To make high quality composites and hybrid composites from jute through chemical processing and to increase the versatility of jute.
2. To make high quality pulp, cellulose, viscose rayon, perishable bags and paper from jute in an
environmentally friendly and easy way which can be used as raw material in various factories and will increase the versatility of jute.
3. To promote jute and jute fabrics in various grades through chemical treatment.
4. To make various valuable materials for use in industry including charcoal, activated carbon from jute and jute sticks.
5. Jute is modified through sulfonation and etherification and mixed with cotton and other fibers which can be widely used in textile industry.
6. Making membrane from jute lignin which can be used for gas separation.

Title of the Technology: Microcrystalline Cellulose (MCC) production from jute fiber. Introduction: Jute contains 60-65% cellulose. By chemical process 03 kg jute can make 01 kg Microcrystalline Cellulose. The technology for making microcrystalline cellulose from jute is currently in the chemistry division, which is transferable. Cellulose is widely used in medicine and food industry in Bangladesh. Currently, MCC is imported from abroad. Bangladesh has to import cellulose worth Tk 10,000 core every year. If we can make Microcrystalline Cellulose commercially from jute then this huge amount of foreign currency will be saved and we will be able to export cellulose abroad by meeting the demand of the country. Salient features of the technology: MCC white, odorless, powder substance. It is insoluble in water, acetone, anhydrous ethanol, toluene and dilute acid. MCC has higher crystallinity than other cellulose substances. |

Title of the technology: Production of jute composite from jute. Introduction Jute plastic composites and hybrid composites are made in an easy way at room temperature by mixing polymer resins and a variety of chemicals with jute hessian fabric. The technology for making jute composite from jute is currently in the field of chemistry, which is transferable to industry. Bangladesh currently has to import corrugated sheets, which cost a lot of foreign currency. If we can make jute composite from jute and use it in different sectors, then huge amount of foreign currency will be saved and environmental damage will be less. Salient features of the technology As there is no metal in jute composite so rust will not be attached. It is lighter, stronger and sustainable. It environment friendly and does not have any hazardous elements It does not conduct heat, so the house made of jute is less heated than ordinary tin. Jutin is less dangerous than normal tin when humans and animals are injured by storms or tidal waves. |

Title of the technology: Preparation of charcoal and activated carbon from jute stick Introduction: About 30 to 35 lakh metric tons of jute stick is produced in Bangladesh every year. Most of them are used for cooking fuel and household items. Jute stick is a cheap and readily available raw material for charcoal production in Bangladesh. Charcoal and activated carbon are made from jute stick in the laboratory of Chemistry Division, which is transferable. At present all the activated carbon of Bangladesh has to import from abroad. It is possible to earn about ten thousand crore taka every year by making activated carbon from jute sticks charcoal by exporting it abroad. Salient features of the technology: The role of the government in the production and export of jute stick charcoal is positive. The government has termed it as a green industry. . Jute sticks are readily available as the climate of Bangladesh is suitable for jute cultivation The production process is very simple. Power consumption is comparatively low. It is possible to produce 2 to 4 MT of charcoal per day by investing 5 million to 1 core in setting up a factory. Demand of jute stick charcoal is increasing significantly If we produce 3 lakh tones of charcoal from 15 lakh tones of jute sticks per year, it is possible to earn foreign currency worth around Tk.1500 to 2000 core but if it Activated carbon then the amount will be 10000 core. |

Title of the technology: Production of pulp and paper from jute fiber Introduction Pulp, cellulose and paper made from jute are simple, eco-friendly and profitable way. Technologies for making pulp and paper from jute are currently in the chemistry division, which can transferable. The pulp for making paper in Bangladesh is imported from abroad. Work is underway to make viscose from the pulp. Commercial production of jute pulp from jute will reduce the import of pulp from abroad and the use of jute will increase tremendously. This will save a lot of foreign currency. Salient features of the technology Bangladesh is facing acute shortage of fiber for its decorative and paper industries. On the other hand, the demand of paper and paper products is increasing day by day. In this case, jute can be used as a significant raw material for making pulp, paper, cellulose and viscose rayon. |

Title of the technology: Production of fireproof and waterproof jute product Introduction: Jute products have been treated with a mixture of chemicals and made fire retardant and water resistant. For preparing diversified jute products, this technology can be used and that will help to increase the use of jute.. The technology is currently in the chemistry division, which is transferable. Salient features of the technology : Production of fireproof and waterproof jute yarn and cloth. Less time consuming, cost effective and safe process. |
