It has been estimated that livestock manure contributes about 240 million metric tons of carbon dioxide equivalent of methane to the atmosphere and represents one of the biggest anthropogenic sources of methane. Considering that methane is the second biggest contributor to global warming after carbon dioxide, it is imperative that ways and means are developed to capture as much of the anthropogenic methane as possible. There is a major associated advantage of methane capture: its use as a source of energy which is comparable in 'cleanness' to natural gas. The present review dwells upon the traditional ways of methane capture used in India, China, and other developing countries for providing energy to the rural poor. It then reviews the present status of methane capture from livestock manure in developed countries and touches upon the prevalent trends.
据估计,牲畜粪便向大气排放了约 2.4 亿吨二氧化碳当量的甲烷,是人为甲烷排放的最大来源之一。考虑到甲烷是仅次于二氧化碳的第二大温室气体排放源,因此必须开发尽可能多地捕获人为甲烷的方法和手段。甲烷捕集具有一个主要的相关优势:将其用作能源,其清洁度可与天然气相媲美。本综述探讨了印度、中国和其他发展中国家用传统方法从牲畜粪便中获取能源,以向农村贫困人口提供能源。然后,它回顾了发达国家从牲畜粪便中捕获甲烷的现状,并探讨了当前的趋势。
