Selected biomass such as mango leaves and acacia leaves convert it in to powder form by using shredder having a capacity of 5 kg. and sieved through 2 mm size sieve to achieve the desired size of raw material. Suitable raw material combinations were made for briquetting process by manually. Then it is used as a input for briquetting machine to produce briquetted sample. Briquettes were prepared by adding water and cow dung as binder in each selected biomass sample. Wooden trays were kept in the front of the die portion to collect briquette suitably. The different combinations of briquettes were prepared as shown in Table 1.
