This Catalyst proposal aims to assess the feasibility of using bioenergy crops (i.e. crops grown for energy production, rather than food) for the recovery and decontamination of polluted water. Bioenergy crops could be a valuable way forward for improving water quality, as they can undertake or assist in several ecosystem processes such as: 1) removal of toxic chemicals from contaminated water (and soil); 2) using up the nutrient present in waste waters; 3) stabilising wastes and improving the look of derelict land; 4) providing a place for wildlife; 5) generating a low carbon footprint, through the provision of fuel. Our proposal to direct research to assess the potential role for biomass crop in waste effluent management is driven by the fact that climate change and population shifts are increasing pressure on the world water resources. This means that in the future we will need to reconsider how we deal with domestic and industrial waste waters. In particular, we will need to think of these effluents as a resource, rather than just seeing them as a problem due to the excess nutrients, pharmaceuticals, 'trace' metals, nanoparticles, microorganisms they can contain. During this initial phase, we will bring together a partnership that will examine the suitability of using bioenergy crops as a mechanism for: 1) harvesting nutrients; 2) breaking down pollutants; 3) lowering the abundance of antibiotics resistance genes; and 4) decrease the number of human pathogens in waste water effluents. The selection of bioenergy crops will be based not only on the need to maximise biomass production, but also their potential suitability for water quality improvement and also the additional ecosystem service they can provide. We will work with experts from academia, industry, NGOs and government to comprehensively review issues relevant to the development of the technology. We will organise two workshops to discuss the proposal aims in detail. The first of these will include a range of organisations from different fields with a stakeholder or beneficiary interest in the area. The workshop participants will be asked to consider two potentially contrasting strategies for tackling the resource recovery challenge: 1) a pragmatic approach that will focus on how innovation can complement existing technology; and 2) a visionary approach that would aim to more radically change the way we deal with waste effluents. Comprehensive reviews of the extensive literature on phytoremediation will be conducted that will help to identify the most feasible may forward (e.g. choice of species, growing conditions, effectiveness of pollutant and pathogen removal). These results will be published in a review article on the evidence base for using bioenergy crops for the recovery and remediation of waste water originating from farms, households and industry (e.g., shale gas fracking fluid). A second workshop will be attended by a subset of the initial workshop attendees with the remit to produce a solutions-oriented Research Grant application to NERC.

该催化剂提案旨在评估使用生物能源作物（即种植用于能源生产而不是食物的农作物）来恢复和污染污染水的可行性。生物能源作物可能是改善水质的宝贵途径，因为它们可以进行或协助几个生态系统过程，例如：1）从受污染的水（和土壤）中取出有毒化学物质； 2）用废水中的营养素使用； 3）稳定废物并改善废弃土地的外观； 4）为野生动植物提供一个地方； 5）通过提供燃料，产生低碳足迹。我们指导研究以评估生物质作物在废物废水管理中的潜在作用的建议，这是由于气候变化和人口变化正在增加对世界水资源的压力。这意味着将来我们将需要重新考虑如何处理国内和工业废水。特别是，我们需要将这些废水视为一种资源，而不仅仅是由于多余的营养，药品，“痕量”金属，纳米颗粒，微生物，它们可以包含的微生物。在此初始阶段，我们将汇总一个合作伙伴关系，该伙伴关系将研究使用生物能源作物作为一种机制的适用性：1）收集营养； 2）分解污染物； 3）降低抗生素耐药性基因的丰度； 4）减少废水废水中人类病原体的数量。生物能源作物的选择不仅基于最大化生物量生产的需求，而且还基于其潜在的水质改善适合性以及他们可以提供的其他生态系统服务。我们将与学术界，工业，非政府组织和政府的专家合作，全面审查与技术开发相关的问题。我们将组织两个研讨会，以详细讨论该提案的目的。其中的第一个将包括来自不同领域的一系列组织。研讨会的参与者将被要求考虑应对资源恢复挑战的两种潜在对比的策略：1）一种实用方法，将重点介绍创新如何补充现有技术； 2）一种有远见的方法，旨在更加根本地改变我们处理废物废水的方式。将对有关植物修复的广泛文献进行全面评论，这些文献将有助于确定最可行的可能的可能（例如，物种的选择，生长条件，污染物的有效性和去除病原体的有效性）。这些结果将发表在有关使用生物能源作物以恢复和修复农场，家庭和工业的废水（例如页岩气水压裂液）中的证据基础的评论文章中发表。最初的研讨会参与者的一部分将参加第二次研讨会，并向NERC提供面向解决方案的研究赠款申请。
