Abstract/ Executive Summary:

Now a day’s fuel and energy is a burning issue in Bangladesh and in this sector the country passing a critical period. So keep attention on the alternative source of fuel and energy is now the demand of time. Press mud the waste product of sugar mill may be a great alternative source of fuel and energy. Sugar mill produces about 3.50%-4.0% press mud of total supplied cane. It does not have much fertilizer value and most sugar mills consider it to be a waste and a nuisance. However laboratory studies showed that it is easily biodegradable and can produce much higher biogas yield than cow dung. It is reported in an Indian publication a biogas yield of 165 liters of biogas per kg. press mud with a processing time of 35 days was observed during monitoring of stabilized biogas plant. Also outlet slurry is a better soil conditioner than press mud. In depth research on biogas from press mud in Bangladesh yet not done. So it is urgent necessity to evaluate performance of press mud for producing biogas.

Keywords: Biogas, Pressmud,

Location: Bangladesh Sugarcane Research Institute, Ishurdi, Pabna.

Start Date: 10-01-2010

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Sugar beet

Objectives:

i.To promote appropriate technological options to recycle the press mud to produce biogas and organic manure.

ii.To enhance the economic viability of waste treatment methods and to minimize adverse environmental impacts on the surrounding.

iii.To enhance the economic viability by the use of the produced biogas as energy source to meet heat and/or electricity requirement and selling organic manure.

Methodology:

The following steps would be followed to complete the programme; a. Collection of batch reactors b. Collection and storage of press mud c. Analysis of press mud d. Dilution of press mud at different solid concentration (4 to 14%) e. Addition of digestion enhancing substances, ie TSP, urea f. Digestion of diluted press mud in the batch reactor g. Measurement of produced biogas h. Analysis of produced biogas i. Determination of hydraulic retention time j. Analysis of bio slurry
