A systematic review using the PRISMA protocol searched for literature on food-waste based hydroponic fertilisers (FWBHF), identifying 6,840 papers with search terms combining "food-waste," "hydroponic," "fertiliser" and "organic," narrowing to 308 papers by title and abstract relevance and ultimately including 37 papers in the final review. The review sought to identify major challenges limiting yield outcomes in food-waste based hydroponic systems, explore conventional and non-conventional improvements, and propose a standardized reporting framework for future research, framed against a backdrop of an estimated 931 million tonnes of food wasted globally in 2018.
