Despite improved recycling infrastructure and public awareness, the UK still sends a staggering 17 million tonnes of municipal solid waste into landfill every year. This leads to the build up of leachate, the liquid which drains from a landfill site. Leachate contains trace chemicals, which can have strong contaminating effects on the environment, and therefore effective treatment methods are required. More to the point, however, ambitions for waste management should go beyond protection of human health and the environment, with conservation of energy and recovery of natural resources high on the agenda.This translational project aims to demonstrate an integrated process for leachate treat went and resource recovery. It involves three innovations: a novel physical pre-treatment, enhanced treatment with adaptively evolved microbial consortia and resource recovery through efficient biomass harvesting, and hence, contributing to the UK circular economy. The outcomes cut across several NERC research priority themes e.g. 'sustainable use of natural resources' and 'environment, pollution and human health.'Leachate can vary considerably in composition, depending on the age and type of waste within the landfill, containing both dissolved and suspended organic and inorganic material. Viridor Waste Management Ltd is the third largest waste management organisation in the UK, owning over 40 sites. Approximately half the sites use foul sewers to carry contaminated wastewater to a sewage works for treatment, the rest is either transported using tankers or released to surface waters. The total annual leachate production is 1,056,716 m3 and the operational costs vary between £4-£10 per m3 (e.g. disposal costs, energy or chemicals used). The previous work includes isolation of natural microbial consortia from leachate, novel harvesting method development and estimation of potential resources recovered. The main translational activities in this project are to design and build a pilot scale photobioreactor that is fitted with all the innovations from previous NERC and non-NERC funded research. This will be installed by Varicon Solutions, TUOS Research Technician and staff at Viridor at a local landfill site (Erin). Pre-processed leachate will be fed into the photobioreactor and growth and operating parameters carefully monitored. The data will be used in a techno economic assessment for Viridor but also other end-users. An easy-to-use Resource Recovery calculator will also be created. The process will be filmed in time-lapse and used to make a video for marketing, knowledge exchange and educational purposes. Both the video and photobioreactor system will be demonstrated at a relevant Trade Show in late 2017/early 2018.The ultimate aim is to demonstrate the progress of the NERC funded research up technology readiness levels with industrial, societal and environmental impact, together with economic benefits for the project partner and wider waste management community.

尽管回收基础设施和公众意识有所改善，但英国每年仍有1700万吨城市固体废物进入垃圾填埋场。这导致了渗滤液的积累，即从垃圾填埋场排出的液体。渗滤液含有微量化学物质，对环境有很强的污染作用，因此需要有效的处理方法。然而，更重要的是，废物管理的目标应该超越保护人类健康和环境，节约能源和回收自然资源是议程上的优先事项。这个翻译项目旨在展示一个综合的过程，处理渗滤液和资源回收。它涉及三个创新：一种新的物理预处理，增强处理与适应性进化的微生物财团和资源回收，通过有效的生物质收获，因此，有助于英国循环经济。这些成果跨越了NERC的几个研究优先主题，例如“自然资源的可持续利用”和“环境，污染和人类健康”。“渗滤液的成分可能有很大的不同，取决于填埋场内废物的年龄和类型，其中含有溶解和悬浮的有机和无机物质。Viridor废物管理有限公司是英国第三大废物管理组织，拥有40多个场地。大约一半的地点使用污水管将受污染的废水运送到污水处理厂进行处理，其余的则用油轮运输或排放到地表沃茨。渗滤液年产量为1，056，716立方米，运营成本为每立方米4- 10英镑（例如处置成本、所用能源或化学品）。以往的工作包括从渗滤液中分离天然微生物菌群，开发新的收获方法和估计潜在的资源回收。该项目的主要转化活动是设计和建造一个中试规模的光生物反应器，该生物反应器配备了以前NERC和非NERC资助研究的所有创新。这将由Varicon Solutions、TUOS研究技术员和Viridor的工作人员在当地垃圾填埋场（Erin）安装。预处理的沥滤液将被送入光生物反应器，并仔细监测生长和操作参数。这些数据将用于Viridor以及其他最终用户的技术经济评估。还将创建一个易于使用的资源恢复计算器。这一过程将以延时方式拍摄，并用于制作视频，用于营销、知识交流和教育目的。视频和光生物反应器系统将在2017年底/2018年初的相关贸易展上展示。最终目的是展示NERC资助的研究进展，以及对工业，社会和环境的影响，以及项目合作伙伴和更广泛的废物管理社区的经济效益。
