Investigations into the viability of converting waste from anaerobic digester biogas plants into value-added customizable fertilizers

厌氧消化是一种利用微生物将生物质转化为甲烷气体并结合富含营养物质的废物的过程-这种产品被称为消化物。这种转化产生的消化液可用于给植物材料施肥，从而减少无机合成肥料的使用。与无机肥料相比，有机肥的使用，例如由厌氧消化产生的有机肥，不太容易浸出和燃烧目标植物。此外，有机肥的使用可以通过改善土壤结构和增加微生物活性来帮助改善土壤健康，并为植物提供更持久的营养，因为大多数有效氮是随着时间而不是一次全部释放出来的。然而，尚不清楚消化产生的废物是否会对植物产生不利影响。此外，产品的理想形式和应用率目前尚不清楚。

Anaerobic digestion is a process that utilizes microorganisms to convert biomass into methane gas combined with a nutrient rich waste product - this product is known as digestate. The digestate from this conversion can be used to fertilize plant material and, as a result, reduce the use of inorganic, synthetically produced fertilizers. The use of organic fertilizers, such as those produced from anaerobic digestion, are less prone to leaching and burning of the target plants as opposed to inorganic fertilizers. Additionally, the use of organic fertilizers may help improve soil health by improving soil structure and increasing microbial activity, and provides longer lasting nutrition for the plants as most of the available nitrogen is released over time rather than all at once. However, it is unknown if there are any adverse effects of the waste products produced by digestion on the plants. Additionally, the ideal form of the product and rates of application are unknown at this time.
