Abstract

The report is structured as follows. Chapter 2 presents the background to this study. Based on secondary data, it first describes the rice milling sector to illustrate the characteristics of the sector and to establish the importance of small scale parboiling rice mills. No secondary data were available either on the socio-economic characteristics of the user group or on the attitudes to technological change among owners and operators of rice mills. This information was important to the design of the project methodology; for indicating the nature of technological improvements acceptable to user groups; for issues of affordability and for subsequent dissemination activities. Section 2.3, draws on the baseline survey carried out in Phase 1, to analyse these characteristics. Chapter 3 first analyses the characteristics of the traditional furnace design and then demonstrates how the new design of furnace-boiler unit has increased combustion efficiency by more than the project objective; improved the working conditions of the workers and increased profitability of the owners. It also sets out the potentials and limitations for wider replications. Chapter 4 focuses on enhancing the production of briquettes using husk from parboiled rice. It describes the current procedures used for briquette production, the difficulties of using husk of parboiled rice, and the improvements developed by this project to address these constraints. Chapter 5 discusses the wider socio-economic benefits that could be generated by the rice husk and bran saved by improved combustion efficiency. It also shows that briquettes, where available, have become the poor man's fuel. Chapter 6 initially set out the characteristics of the rice husk ash in Bangladesh. It then describes the current uses in other countries and identifies potential alternative uses in Bangladesh. Chapter 7 describes the dissemination activities already undertaken and their outcomes and then outlines further dissemination activities that could potentially enhance uptake. Chapter 8 will conclude the report with recommendations and identify further research needs in biomass fuel use.
