Fertilizer is one of the most significant on-farm input cost (~25%) for modern agriculture. Price instability due to a substantial increase in world demand for fertilizers, limited recourses (P and K) and costs associated with production has put financial pressure on farmers in Australia. On the flip side, there is substantial amount of nutrients (nitrogen, phosphorus and potassium) in agro-industrial waste streams in Australia, if recovered fully could significantly reduce reliance on expensive manufactured fertilizers. There is a need to assess nutrient resources from the Australian agro-industrial waste streams and their potential for processing into mineral fertiliser products. The key objectives of the project are to demonstrate nutrient recovery technologies at pilot scale, develop novel nutrient recovery technologies, and agronomic testing of the recovered product.
