Reusing Effluents from Agriculture to unLock the potential of Microalgae

REALM将通过在处理水和从空气中捕获二氧化碳的同时以较低的成本生产微藻，将无土农场富含营养的排水转化为有价值的水。这一概念将增加微藻生产和无土耕作的循环性和盈利能力。NordAqua和ALGACYCLE项目（分别是NordForsk和EEA）已经在芬兰和葡萄牙证明了这一概念的可行性，现在REALM的目标是在工业规模上证明它。因此，将在荷兰和芬兰设置两个验证设施，在葡萄牙和西班牙的无土温室附近设置两个示范设施。利用SABANA项目（H2020）的专业知识，这些设施将利用温室中富含营养的废水，在浊积机制（连续收获）下运行光生物反应器，以最大限度地提高生产率。种植和收获单元将由光伏能源供电，并由新型传感器自动管理，而基于人工智能的预测模型和基于云的监控系统将协助生产。微藻生物质将由当地下游加工单位加工，以乳制品行业供应链为工作模式。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，预计将使微藻生产成本降低50%，节省下来的成本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，以便整个欧盟的相关利益攸关方可以复制所演示的概念，同时实现《欧洲绿色协议》确立的若干目标，例如通过促进绿色工业与自然合作，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 aimsto demonstrate it at an industrialscale. 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 wastewaters 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 offersustainable 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.
