The experiments were carried out in the Department of Agric. Eng. Faculty of Agric. Menoufia Univ., Laboratory of Soil Science Department., Faculty of Agric. Menoufia Univ., resistance of concrete laboratory, Civil Engineering Department, Faculty of Engineering, Menoufia Univ. and biomass laboratory of the New and Renewable energy authority, Nasr City, Cairo. To determine the parameters leads to achieve the aim of this study. The experimental work involved four stages as follows: Measuring some physical properties for corn stalks. Chopped corn stalks using hammer mill at cutting speed 1600 rpm and at different three moisture content (8%, 9% , 10%) . Press material chopped into screw press machine at a pressure of 100 MPa and temperature of 170-175ºC at three moisture content for corn stalks (8%, 9% , 10%) . Measuring some quality properties of pressed briquettes such as the durability, hardness, compression ratio, bulk density, calorific value, and elasticity. The results obtained from this study can be summarized as the following: Physical properties for corn stalks. Measuring some quality properties of corn stalks briquettes produced by screw press.
