Abstract/ Executive Summary:

Jute is grown abundantly in Bangladesh. As a result, about 77 jute industries are established in this country. Huge quantities of jute wastages of these jute mills are not properly utilized with the exploration of their maximum potential. In this research work sixteen types of fuel cakes were produced from jute mill wastes, cow dung, clay, starch, molasses and water by binary, tertiary and quaternary mixtures in definite ratios. These fuel cakes were dried in open atmospheric conditions. The fuel cakes types 4 (containing 1.00 Kg of dust, 1.50 L of water, 1.00 kg cow dung) and 3 (containing 1.00 Kg of dust, 1.50 L of water, 0.50 kg cow dung) were the best among all the fuel cakes. These two cakes showed the maximum caloric value, maximum burning time and heat generation among all the fuel cakes. This technology can be easily used for the production of fuel cakes from jute mills waste for industrial and domestic uses. In tropical and other developing countries, mill wastes can be properly utilized in the industry, as a source of energy support and for domestic purposes. It will also keep the environment free of pollution by the consumption of waste materials

Keywords: Jute waste, Fuel cake, Calorific value, Heat generation.

Start Date: 01-01-1988

End Date: 30-06-1988

Program Area: Postharvest and Agro-processing

Commodity: Jute

Objectives:

1.Development of fuel cake from jute waste and studies on the different parameters of the fuel cake.

2.Development of improved types of fuel cake and its production from jute waste for industrial and domestics use.

Methodology:

Jute mill wastes were collected from Adamjee Jute Mills. Cow dung, clay, starch, molasses were collected from local market, BJRI premises, were used in this preparation. Sixteen types of fuel cakes were produced from jute mill wastes, cow dung, clay, starch, molasses and water by binary, tertiary and quaternary mixtures. For homo-geneization, the mixed materials were shaked for 30 minutes in the laboratory shaker with known shaking rate. After making their homogeneous mixture, the mixture materials were put in quadrilateral shaped deices of known volume. The quadrilateral shaped cakes were taken out from the dice after processing (3 tons/square inch) for 12 hours and then the cakes were exposed to sun light for 24 hours for drying. The dried cakes were then studied for different fuel values such as caloric value, temperature, burning time, duration of flame, in minutes, and ash content with the method developed in the BJRI laboratory. Jute mill waste (100%) with jute stick, bark, fiber, bark powder, bark powder and send with the percentage of 5.35%, 40.05%, 4.6%, 1.00% and 49% were used in this work respectively.

Achievement/Findings:

The fuel cakes types 4 (containing 1.00 Kg of dust, 1.50 L of water, 1.00 kg cow dung) and 3 (containing 1.00 Kg of dust, 1.50 L of water, 0.50 kg cow dung) were the best among all the fuel cakes. The calorific value of fuel cake no. 4 and 3 were 23.07cal/gm and 2265.73 cal/gm. The burning time of these two fuel cakes were 32 minutes and 34 minutes while the temperature produced by them were 55^OC and 54^OC respectively. These two cakes showed the maximum caloric value, maximum burning time and heat generation among all the fuel cakes. This technology can be easily used for the production of fuel cakes from jute mills waste for industrial and domestic uses.
