Using rice husk briquette (RHB) production machines for cooking energy in Bangladesh is a big challenge. The main problem is turning rice husks, which are leftovers from rice farming, into briquettes that people can use for cooking. These machines need to be affordable and easy to use, especially in rural areas where most rice husks are found. The briquettes that these machines make need to be good quality and burn well. They should be a better option than traditional cooking fuels like wood or charcoal, which can cause health problems because of the smoke they make. The briquettes should also fit with the cooking stoves people already have. Another issue is collecting the rice husks and getting the briquettes to the people who need them. This includes figuring out how to store and transport them. Plus, people need to learn about the benefits of these briquettes and how to use them. Solving these problems is really important for making RHB production machines a good solution for cooking energy in Bangladesh. This can help the environment by using up waste from rice farming and also improve people’s health by offering a cleaner way to cook.
