Most countries in the world depend on energy, and it is suggested that it be generated from renewable sources that do not have a negative impact on the environment. The avocado pit is a residue that originates from the consumption of avocado pulp and can be used as biomass due to its potential calorific value. Thus, this research developed ecological briquettes from avocado pit waste as biofuel. The briquettes were made from a mixture of avocado pit, sawdust and cassava binder in different proportions. The briquettes were cylindrical in shape, 7 cm long and 5 cm in diameter, and their calorific value, combustion time, humidity, ash content and amount of CO2 emissions were evaluated. The results indicated that the best proportion for obtaining the ecological briquette was 70 g of avocado pit, 20 g of sawdust and 30 g of binder diluted in 120 ml of water. In addition, the briquettes showed reductions in CO2 emissions and high calorific value. Finally, it is concluded that the ecological briquettes are a great alternative as biofuel and could be used as a source of energy for different domestic cooking activities in rural areas and recreational and leisure centers, benefiting the environment.
