    • Animal waste such as fecal material from swine, chicken, turkey, and cattle is converted into useful forms such as fertilizer, other types of soil builders, and even nutrient feed additives. Devices, systems, and methods are provided that allow economical conversion and in many instances, alleviate the production and release of undesirable gases such as sulfide and ammonia. In one embodiment, undesirable anaerobic and facultative anaerobic bacteria are killed at a greater rate than desirable soil compatible aerobic bacteria. The use of low temperature killing diminishes off gassing commonly associated with other techniques, and the use of gas trapping additives such as zeolites provides enhanced soil building qualities such as slow release of nitrogen and slow release of moisture to soil. The methods allow convenient adjustment of composition, allowing conversion of waste into tailored designer fertilizer suited for particular soils. Other embodiments provide other soil building qualities as well as nutrient qualities for feedstock used in animal husbandry such as aquaculture.
    • 诸如猪,鸡,火鸡,牛等的粪便物质等动物废弃物被转化为有用的形式,例如肥料,其他类型的土壤助剂,甚至营养饲料添加剂。 提供了允许经济转换的装置,系统和方法,并且在许多情况下,减轻了不期望的气体如硫化物和氨的产生和释放。 在一个实施方案中,不期望的厌氧和兼性厌氧细菌以比所需的土壤相容性需氧细菌更大的速率被杀死。 使用低温杀死减少通常与其他技术相关的气体,并且使用气体捕获添加剂如沸石提供增强的土壤建筑质量,例如缓慢释放氮气并缓慢释放土壤。 这些方法可以方便地调整组合物,从而将废物转化为适合特定土壤的定制设计师肥料。 其他实施例提供其他土壤建筑质量以及用于畜牧业如水产养殖的原料的营养质量。
