This lecture explores the development of a briquette making machine to reduce wood waste by using sawdust as an energy source, aiming to increase profitability and transform by-products into usable resources. The project involved designing a machine for forming briquettes from collected sawdust, addressing constraints such as space, transportability, and safety. A prototype was created to validate theoretical concepts, featuring elements like a matrix heater to increase briquette density. The machine operates through a series of steps, compressing sawdust into briquettes, with the density gradually increasing over time. The prototype testing led to adjustments for the final machine, ensuring it meets client demands for a renewable energy source from wood waste.
