A large population of rural or hills of Uttarakhand is still facing the energy crisis in the household as well as for small and medium scale industries due to insufficient supply of fuel and electricity. The supply of coal and LPG is irregular for far-flung areas which make them bound to depend solely on wood for fuel. Therefore, a study was undertaken to evaluate the physical and thermal properties of pine needle biochar briquettes to check its feasibility as sustainable solid biofuel for the hills of Uttarakhand. Pine needle biomass was collected from the pine forest and converted into biochar. Further, biochar was mixed with three binders i.e. soil, cement and lime in different ratio on weight basis briquettes were formed using screw type briquetting machine. The physicochemical and thermal properties of briquettes were evaluated. The highest density of biochar briquettes was found to be 435.58 kg m-3 for ratio B50:C50 which comprise equal percentage 50% of biochar and cement as binder. The biochar binder ratio B50:L50 (biochar with lime) has the highest shattering resistance of 90.6 %. Pine needle biochar briquetting can be a solution by providing alternative household solid fuel replacing wood and coal which will help to save the environment by reducing the deforestation and fire hazard.
