Bangladesh has significant potential

Bangladesh has significant potential in the rice industry. Rice serves as a major food source in the country, accounting for approximately 93% of total food production. Annually, Bangladesh produces an average of 35.00 million metric tons of paddy, which are processed in local rice mills. These mills, typically small industries located in rural areas, process paddy obtained from local markets through farmers to supply rice.

During the milling of dried parboiled rice, a substantial amount of rice husk is generated, resulting in approximately 7.45 million metric tons of rice husk that pose disposal challenges. Rice husks account for one-fifth of the weight of dried paddy rice and are currently utilized as a heat energy source, representing the largest biomass source in Bangladesh and contributing 22% of the total 39 million tons of biomass produced.

Typically, 10% of rice is hulled immediately, while the remaining 90% is parboiled before hulling. The by-product of rice hulling, rice husk, is used as boiler fuel to produce steam for parboiling the paddy, with the remainder either sold or misused.

Most rice mills in Bangladesh operate under industrial connections from BPBD and REB power, facing high tariffs and operational challenges that increase production costs. A consistent supply of low-cost power and steam could benefit rice mill operations and food production.

A significant number of people in Bangladesh depend on rice husk as a crucial domestic fuel source, but its inefficient use negatively impacts the health of users and workers involved. This inefficiency persists due to the lack of advanced technology to maximize the use of rice husk as an energy resource. Additionally, the current practice of rice husk briquettes in Bangladesh is energy-intensive. Therefore, an alternative approach, such as electricity generation through rice husk gasification in rice mill compounds, could enhance the situation.

Implementing more advanced technologies like rice husk gasifiers with dual-fuel IC Engines or single-fuel SI (gas) engines can improve the utilization of rice husk as an energy resource. This could lead to more efficient and environmentally friendly energy production in the rice industry in Bangladesh.
