The experiment tests have been carried out at two factors which are constant temperature of 37 C\u00b0, and the others is of variable temperature in the range of (7 \u2013 13 C\u00b0). A set of lab anaerobic digesters of 1 litter has been used to execute the experimental work, which has a period of 30 days. The produced biogas under constant temperature condition was 262 LN\/Kg VS which is 167.3% more than that produced under variation temperature condition which was 98 LN \/ Kg VS. The pH of the anaerobic digestion process was measured daily using a specially designed laboratory device. The measured pH values were suitable for the anaerobic digestion process and ranged between (5.4 &#8211; 8.8). The high organic matter content of BW and the richness of this residues in carbohydrates, make it a good material to product biogas.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Keyword: <\/strong>Biogas, Anaerobic digestion, variable temperature, broad beans wastes.<\/span><\/p>\n<p><span style=\"font-family: 'times new roman', times, serif;\"><strong>Full paper in Arabic:\u00a0<a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v12n3p37.pdf\">PDF<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Daoud Malouk*(1) (1).
