Briquetting is the most widely-used waste compaction technology. Briquette quality is evaluated mainly by briquette density. Briquette density is very important for the impact of technological parameters compacting pressure, burning speed, briquette stability, etc. Briquettes made by hydraulic briquetting presses are of the highest quality. This developed hydraulic briquetting system is manufactured in Terme Industrial zone Samsun Turkey. The objective of the present study is to give theoretical analyses of parameters which have an impact on briquette quality. Hazelnut husk briquettes were dried up to 13 15 % moisture content and they were grinded into (2-5)-(7-10) mm size and were pressed under 160 MPa pressure. The physical-mechanical properties of the briquettes were investigated.
