Abstract
Anaerobic Digestion (AD) at digester is considered as an environmentally friendly
technology to manage biodegradable waste like cattle dung. However, systematic
environmental impact associated with different phases of life cycle of AD at digester is
necessary to qualify the technology as environmentally friendly. Several such studies
have been carried out in different parts of the world, however, such quantification may
not be applicable under Nepalese conditions as the inventory and management of
digestate and other technical parameters may be different. Very limited environmental
impact studies have been conducted under Nepalese scenario and so the aim of our
study is to estimate the greenhouse gases emissions (GHGE) associated with the
production of biogas at Rastriya Gai Anusandhan Kendra, Rampur, Chitwan
(community biogas plant) systematically, identify the hotspots contributing GHGE and
recommend the mitigation strategies of GHGE. ISO 9001 based life cycle assessment
(LCA) approach was employed as a methodological framework for the study. Primary
inventory data were collected through field visits based on pre structured questionnaire
and wherever necessary, secondary data were collected from the official data
providing center of the country as well from the published scientific literatures.
