到2050年，全球人口预计将达到90亿，人类需要平衡对粮食、能源和自然资源日益增长的需求，同时可持续地管理生态系统及其提供的重要服务。农业的集约化，包括使用有限来源的肥料，导致了广泛的土壤退化，这增加了粮食生产成本和二氧化碳排放，威胁到粮食安全。生物能源部门在促进形成循环经济方面具有巨大潜力。本文介绍了利用生物质热转化（灰）和厌氧消化（消化）产生的营养废物流作为替代传统肥料的可持续土壤改良剂的科学、监管和社会经济障碍。有人认为，虽然将灰烬和消化物结合起来补救对生态系统的许多威胁，并提供一个市场来激励可再生生物能源计划的能力是有希望的，但需要逐步改变对“废物”的看法，从一个昂贵的问题转变为具有环境和经济价值的产品。这只能通过科学家、监管机构和最终用户之间充分知情的互动来实现，以提高该部门创新的传播和速度。
As the global population is expected to reach 9 billion by 2050, humanity needs to balance an ever increasing demand for food, energy and natural resources, with sustainable management of ecosystems and the vital services that they provide. The intensification of agriculture, including the use of fertilisers from finite sources, has resulted in extensive soil degradation, which has increased food production costs and CO2emissions, threatening food security. The Bioenergy sector has significant potential to contribute to the formation of a circular economy. This paper presents the scientific, regulatory and socioeconomic barriers to the use of the nutrient waste streams from biomass thermal conversion (ash) and anaerobic digestion (digestate) as sustainable soil amendments for use in place of traditional fertilisers. It is argued that whilst the ability of combined ash and digestate to remedy many threats to ecosystems and provide a market to incentivise the renewable bio-energy schemes is promising, a step-change is required to alter perceptions of ‘waste’, from an expensive problem, to a product with environmental and economic value. This can only be achieved by well-informed interactions between scientists, regulators and end users, to improve the spread and speed of innovation with this sector.
