Reusing Effluents from Agriculture to unLock the potential of Microalgae

REALM将通过以较低的成本生产微藻，同时处理水和从空气中捕获二氧化碳，将无土农场富含营养的排水沃茨转化为价值。这一概念将提高微藻生产和无土农业的循环性和盈利能力。NordAqua和ALGACYCLE项目（分别为NordForsk和EEA）已经证明了这一概念在芬兰和葡萄牙的可行性，现在REALM的目标是在工业规模上进行演示。因此，将在荷兰和芬兰安装两个验证设施，并在葡萄牙和西班牙的无土温室附近部署两个示范设施。利用SABANA项目（H2020）的专业知识，这些设施将利用温室中营养丰富的废水沃茨，在恒定浊度条件下（连续收获）运行光生物反应器，以实现最大生产力。生长和收获单元将由光伏能源供电，并由新型传感器自动管理，而A.I.基于云的预测模型和基于云的监控系统将有助于生产。微藻生物质将由当地下游加工单位以乳制品行业供应链为工作模式进行加工。这一概念将通过关闭营养循环为农民提供可持续的废水处理技术，预计将微藻生产成本降低50%以上，其节省的资金将用于提高拟议的微藻产品（即农用化学品和水产饲料）的竞争力。将开发一种商业模式，建议在无土温室旁边安装多个微藻生产设施，并连接到一个集中处理设施。REALM产生的结果将得到传播，以便欧盟所有相关利益攸关方都能复制所展示的概念，同时针对欧洲绿色交易所确立的若干目标，例如与自然合作，通过促进更绿色的产业来改善人类健康。

REALM will transform nutrient-rich drain waters from soilless farms into value, by producing microalgae at reduced costs while treating water and capturing CO2 from the air. This concept will increase the circularity and profitability of microalgal production and soilless farming. The NordAqua and ALGACYCLE projects (NordForsk and EEA, respectively) have shown the feasibility of this concept in Finland and Portugal, and now REALM aims to demonstrate it at an industrial scale. Accordingly, two validation facilities will be installed in the Netherlands and Finland, and two demonstration facilities will be deployed in Portugal and Spain near soilless greenhouses. With know-how from the SABANA project (H2020), these facilities will operate photobioreactors under a turbidostatic regime (continuous harvest) for maximum productivity, using nutrient-rich waste waters from the greenhouses. Growth and harvesting units will be powered by photovoltaic energy and automatically managed by novel sensors, while A.I.-based predictive models and a cloud-based monitoring system will assist production. Microalgal biomass will be processed by local downstream processing units using dairy industry supply chain as a working model. This concept will offer sustainable wastewater treatment technology to farmers by closing the nutrient loop and is expected to reduce microalgae production costs by >50%, whose savings will be used to increase the competitiveness of the proposed microalgae-based products, namely agrochemicals and aquafeed. A business model will be developed to propose the installation of multiple microalgae production facilities, next to soilless greenhouses, and connected to a centralised processing facility. The results generated by REALM will be disseminated so the demonstrated concept can be replicated by relevant stakeholders in all EU, while targeting several objectives established by the European Green Deal, such as working with nature to improve human health by promoting a greener industry.
