The broader impact/commercial potential of this I-Corps project is to promote a liquid organic fertilizer (LOF) produced through a novel patented technology which uses anaerobic accelerated bio-leaching of green plant material or green plant waste. The synthetic free liquid organic fertilizer is a complex solution that contains macro nutrients, micro nutrient as well as organic matter in soluble form. The benefits of the proposed product include: (1) improvement of soil biological activities by providing the soil with soluble organic matter; (2) feeding the plants with soluble macro and micro nutrients; (3) ease of transportation; (4) ease of storage; (5) easy adjustment of the nutrient content through dilution; (6) easy application through irrigation systems and; (7) environmental benefit of carbon sequestration. Since no synthetic chemical is used for LOF production, it has the potential to be used as an economic alternative for currently used organic fertilizers such as fish emulsion and composts by the rapidly growing organic farming industry.This I-Corps project enables the extraction of plants macro and micro nutrients and organic matter from the body of green organic waste such as landscape grass clippings. The proposed novel technology consists of two simultaneous processes of anaerobic digestion and accelerated bio-leaching of organic waste to produce liquid organic fertilizer (LOF). Historically, the use of organic waste for production of organic fertilizer has been through composting. Research has shown that the proposed technology will require less time, lower energy consumption and easily available nutrients when compared to composting. In addition, LOF returns the plant organic carbon back to the soil and contributes to carbon sequestration. Previous studies have also shown that the use of LOF could lead to higher yield in vegetables when compared to synthetic fertilizer.

这个I-Corps项目的更广泛影响/商业潜力是推广一种液体有机肥料，这种肥料是通过一种新颖的专利技术生产的，该技术使用绿色植物材料或绿色植物废物的厌氧加速生物沥滤。合成游离液体有机肥是一种含有大量养分、微量养分和可溶性有机质的复合溶液。拟议产品的好处包括：（1）通过为土壤提供可溶性有机质来改善土壤生物活性;（2）为植物提供可溶性大量和微量营养素;（3）便于运输;（4）便于储存;（5）易于通过稀释调节营养素含量;（6）易于通过灌溉系统施用;（7）碳汇的环境效益。由于LOF生产中不使用合成化学品，因此它有可能被快速发展的有机农业用作目前使用的有机肥料（如鱼乳液和堆肥）的经济替代品。I-Corps项目可以从景观草等绿色有机废物中提取植物宏量和微量营养素以及有机物质。提出的新技术包括两个同时进行的厌氧消化和加速生物沥滤有机废物生产液体有机肥（LOF）的过程。从历史上看，使用有机废物生产有机肥料一直是通过堆肥。研究表明，与堆肥相比，拟议的技术将需要更少的时间，更低的能源消耗和更容易获得的养分。此外，LOF将植物有机碳返回土壤，有助于固碳。以前的研究也表明，与合成肥料相比，LOF的使用可能导致蔬菜产量更高。
