Progress on Carbon-and Nitrogen-transformation and Greenhouse Gas Emission in Composting

Agriculture and animal husbandry have a direct impact on people′s livelihood.Waste recycling is seen as aprudent measure to ensure an economical, as well as environmentally friendly, operation.In practice, composting can not only fulfill such mission, but also prevent pollution and improve safety.It has been an effective means in handling organic solid wastes worldwide for ages.By reviewing published literature and analyzing available data, this paper summarizes the dynamic fate and effects of the greenhouse gas emission, the rules of carbon-and nitrogen-transformation, as well as the microbial interactions during composting.Suggestions for future research are presented.
