In the face of finite sources of conventional phosphorus, and highly energy-intensive and price-sensitive nitrogen, agriculture is challenged to maintain or increase food production and simultaneously reduce its carbon impact. Fertiliser prices are strongly influenced by the crude oil price, reflecting the energy intensity of the manufacturing process. Finite nutrient sources are being depleted, whilst nutrients are lost from the land through crop harvest. It is therefore necessary to identify alternative sources of nutrients which can be safely applied to crops to sustain food production which can be produced with lower carbon impacts, and less environmental damage. The proliferation of the renewable energy sector, as a means of reducing carbon emissions, has resulted in the growth of biomass to energy schemes. Agricultural land is the "expected" sink for digestate in the UK according to government policy since these waste sources are nutrient-rich. However, a number of limitations restrict the use digestate: highly variable composition (both spatially and temporally); undesirable compounds and contaminants presence (excessive metals; plastics residues); lower nutrient content than in manufactured fertilisers (higher volumes applied); logistical constraints (spatial dispersion from source); temporal constraints (application limited to certain periods, thus need for interim storage); uncertainties of crop responses. These undesirable factors have resulted in it being a disposal cost to the AD operator (average £3.73/t in 2013). Ash is similarly plagued by inconsistent composition and other undesirable characteristics and so significant quantities are being disposed of in landfill. For both digestate and ash, their disposal means that nutrients are lost from the cycle, incurring high costs to the renewable energy industry. These limitations present a clear need for development of an alternative product or process which can present an attractive solution to both the bio-energy and agricultural sectors alike.The overarching objective is to develop commercially viable, high quality, consistent, sustainable fertilisers from bioenergy residues. Four main considerations are central to understanding the behaviour of the feedstocks in making a product: nutrient retention, form, and stability of the nutrient during processing; and whether the nutrient will be supplemented by other sources to meet a specification. Considering the aforementioned statements, the overall aim will be achieved through the following:(i) Physico-chemical characterisation of individual waste streams (ash and digestate) and putative fertiliser products, including the identification of other suitable wastes(ii) Assessment of the effects of reaction conditions on nutrient availability and potentially toxic elements presence on the fertiliser product, especially to understand in detail nitrogen retention, Phosphorus speciation and availability and long term stability controlling factors. (iii) Quantification of the impact of ash and digestate mixtures on plant growth and comparison against traditional inorganic fertilisers.(iv) Identification of legislative requirements and commercial considerations of the putative fertiliser products for use in agriculture as factual alternatives to conventional fertiliser applicationsExtensive testing on selected treatments and reaction conditions in the laboratory and plant growth in glasshouse trials will represent and step towards the applicability, commercialisation and viability of the formulated product in an agricultural setting. Benefits of such scenario are reduction in the dependence on phosphorus and nitrogen finite fertiliser resources, contribution to food security and compliance with waste hierarchy and resource recovery.

面对传统磷的有限来源以及高能量和价格敏感的氮，农业面临着维持或增加粮食产量的挑战，只是减少了碳的影响。肥料价格受原油价格的强烈影响，反映了制造过程的能量强度。有限的养分来源正在耗尽，而养分则通过收成从土地上丢失。因此，有必要确定可以安全地应用于农作物的替代养分来源，以维持粮食生产，而粮食产量可以降低碳的影响，而环境损失则较小。作为减少碳排放的一种手段，可再生能源部门的扩散导致了生物量对能量方案的生长。根据政府政策，农业用地是英国消化厂的“预期”下沉，因为这些废物来源是养分丰富的。但是，许多局限性限制了使用摘要：高度可变组成（无论是空间还是临时）；作物反应的不确定性。这些作物反应的不确定性。因素导致它是广告运营商的处置成本（2013年平均3.73/t）。同样，灰分也受到不一致的成分和其他不可避免的特征的困扰，因此在垃圾填埋场中处置了大量数量。对于消化和灰烬而言，它们的处置意味着营养物质因周期而损失，这给可再生能源行业带来了高昂的成本。这些局限性明显地需要开发替代产品或过程，该产品可以为生物能源和农业领域提供有吸引力的解决方案。总体目标是从生物能量保留中开发出商业上可行，高质量，一致，可持续的肥料。四个主要考虑因素是了解原料在生产产品中的行为：养分在加工过程中的养分，形式和稳定性；以及其他来源是否会补充养分，以达到近似陈述，将通过以下各个方面实现总体目的：（i）物理化学表征：物理化学表征（灰烬和消化）和推定的化肥产品和推定的化肥产品以及其他合适的废物（ii）对材料的效果的识别（ii）鉴定的效果（ii）在效果上鉴定出良好的效果，并在营养效果上进行效果，并在营养方面的影响效果。氮保留，磷规范和可用性以及长期稳定性控制因素。 （iii）量化灰分和消化酸盐对植物生长的影响和与传统无机肥料的比较。（iv）确定对推定的肥料产品的立法要求和商业考虑，以便在一致性中用作一致性的事实替代方案，作为常规肥料的替代方案，在常规肥料中施加了对实验室和工厂在实验室中的依赖性和植物的影响，这些依赖于实验室的依赖性和植物的依赖性，这些依赖的依赖是在实验室审判中造成的，这些依赖的依据是造成实验室试验的效果磷和氮有限的肥料资源，对粮食安全的贡献以及对废物层次结构和资源回收的遵守。
