Abstract

Anaerobic digestion (AD) become a crucial method for obtaining a green energy that represented in biogas from organic wastes particularly the animal wastes in rural areas instead of its incineration. This study aims to investigate the biogas yield of a constructed Indian type biogas unit with an approximately volume of 3m3 at Faculty of Agriculture, Zagazig University, Sharkia Governorate, Egypt for biogas generation from dairy cattle dung under cold climate conditions during winter season of 2015. The results revealed that, the dairy cattle dung proved a suitable substrate for the installed biogas digester and produced an average 105L biogas per day for one cubic meter of dairy cattle slurry (8% of TS) without any feedstock for 30 days in winter season in Egypt under psychrophilic conditions of 16.3 to 20.5oC temperature range. Therefore, the environmental affordability of the biogas technology, as a zero-waste engineering and unsound waste management system warrants further study in Egypt.
