Many initial tests were carried out to determine a suitable temperature, moisture content, and compression pressure for briquetting the weed material. Since temperature range 80–105 C were determined to be suitable after these tests, further experiments were conducted in this temperature range. The materials were compressed in the squarer and cylindrical dies at three moisture levels and at three pressure levels at the temperature range determined in the initial tests. Moisture contents of chopped material and briquettes were chosen according to the ASAE Standard S358.2 FEB03 for forages and given in percent wet basis (w.b.). Because moisture content of the raw material was measured to be 7%, moisture levels were chosen to be 7%, 10%, and 13% on wet basis. After two portions of the raw material were conditioned by spraying predetermined amounts of tap water into the samples, each portion was mixed and then covered with a plastic sheet to obtain materials with moisture contents of 10% and 13%. Three pressure levels were obtained within the dies as 15.7,19.6, and 31.4 MPa considering intermediate pressure range of briquetting in cited literature. Outside dimensions of produced briquettes were measured after one week to calculate their densities. An experimental design for cylindrical and squarer briquettes was arranged and applied according to completely randomized plot design as factorial plan. Each test was replicated five times for all factor combinations.
