Generally, briquettes of plain olive cake, OC, lack durability. This work involved mixing OC at 35% moisture with 1 to 4% of wood adhesive or clay loam and compacting the mixture at a stress of 15 to 45 MPa and dwell time of 5 s. An ASAE standard tumbler was used to determine the briquette durability. The results showed that adhesives had substantial effect and increased the durability index by more than 11 times compared to plain OC. Overall, clay loam was the favorable adhesive and when added at 2% and compacted at 35 MPa produced the best desirable outcome.
