    • Methods are provided for processing municipal human waste such that the processed material is greater than 99% free of pathogenic organisms. The processed material can be used as an organic fertilizer or a "Class A" organic fertilizer. The methods include reducing the moisture content of human sludge free of polymeric flocculant to less than about 30% moisture and processing the sludge through an extruder under conditions having a minimum temperature of about 140°C, a residence time of about 30 seconds, and an atmospheric pressure differential of about 40 atmospheres. The methods are economical and have numerous advantages including reduced use of fossil fuel, fast processing time, and production of an odor free organic fertilizer free of many land use restrictions.
    • 提供用于处理城市人类废物的方法,使得处理的物质大于99%,不含病原生物体。 经处理的材料可用作有机肥料或“A类”有机肥料。 所述方法包括将没有聚合物絮凝剂的人体污泥的水分含量降低至低于约30%的水分,并且在具有约140℃的最低温度,约30秒的停留时间和 大气压差约40个大气压。 这些方法是经济的并且具有许多优点,包括减少化石燃料的使用,加工时间快,并且生产没有许多土地使用限制的不含臭味的有机肥料。
