The contribution contains the results of performance tests carried out with the aim to evaluate objectively the quality of briquettes made by the use of two different briquette presses and also in this way to assess the used briquette presses quality. Two briquette presses of firm Briklis were tested, namely the type BrikStar 50 of 65 mm press chamber diameter and the type BrikStar 30 of 50 mm press chamber diameter. For production of fuel briquettes four different materials were used, namely sorted office paper in form of shreds of dimensions 4x18 mm, from white wood-free books in the same shred dimensions, from lime wood chips without bark and from pine wood shavings without bark. All fuel briquettes were made using the automated operation of both briquette presses. From statistical evaluation of the carried out tests it follows that using the briquette press of 65 mm press chamber diameter it is possible to produce quality fuel briquettes only from shreds from office paper and from white wood-free books in form of shreds. The properties of fuel briquettes made from pine wood chips are although worse, but they are still suitable. Briquettes made from lime wood chips do not fulfill the Directive demands. Using the briquette press of 50 mm press chamber diameter the suitable fuel briquettes were made from all four tested materials.
