The research was aimed to know the energy capacity content of briquettes made of coffee husks to replace wood in the production of corn donuts. The efficiency was measured in different test series evaluating the amount of water at constant volume as both wood and briquettes were able to evaporate. In a traditional oven for baking corn donuts it was determined that the briquettes contain 25% more energy than gravel pine wood and that the use of briquettes made from coffee plants does not affect the taste and smell of corn donuts. As a conclusion it can be stated that coffee husk briquettes are suitable to use in ovens for baking corn donuts and can help reduce the amount of firewood.
