Agriculture solid wastes are main pollutants in rural area now.There were nearly 17.3×108t animal manures and more than7×108t crop straws produced in China every year.But most of animal wastes went into environment without any correct treatment.And nearly 10-15% crop straws were burned in the field.There have a lot of environmental problems if agricultural organic solid wastes go into environment just like the way which they going now.Such as damaging soil ability; polluting air quality; influencing transportation and squandering the fertilizer resources when we ignited crop straws in the open air.
