中药渣在主要经济畜禽生产中的应用

中草药药用价值显著,中草药利用后产生的中药渣也有巨大的利用价值。近年来,关于中药渣利用的研究与报道不穷,如将中药渣用于蔬菜栽培等,这些研究均有一定的实践与理论依据。基于此,立足实际,就中药渣在主要经济畜禽生产上的应用做一番研究,以供参考。

Small-Scale Household Biogas Digesters as a Viable Option for Energy Recovery and Global Warming Mitigation--Vietnam Case Study

Biogas from livestock waste is considered as clean and renewable energy in Vietnam. In the last 20 years, in rural and remote areas of Vietnam, there has been a significant increase of small-scale household biogas digesters. Biogas digesters create the benefits of replacing energy and mitigation of climate change caused by greenhouse gas （GHG） emission and deforestation for firewood and charcoal. Livestock waste produces approximately 85 million tonnes every year and continues to increase, meaning there are huge feedstocks for biogas digesters to meet the energy demands in households. However, there are also many constraints on the development programme for small-scale household biogas digester. In Vietnam, the socio-economic situation and the lack of a sustainable energy policy for biogas from livestock sector are hindering the growth of the biogas digester industry. Government subsidies are needed to encourage farmers to participate. This paper will be helpful not only for the sustainable development of household biogas in Vietnam, but also for the developing program of biogas generation in developing countries with similar agricultural economies to Vietnam.
