Nutrients like nitrogen, phosphate, and potassium are abundant in agricultural waste, which includes crop wastes, animal dung, and by-products of food manufacturing. However, poor handling of these wastes frequently results in resource loss, degradation of the environment, and a greater need for artificial fertilizers. Eco-safe nutrient recovery technologies have become well known as sustainable ways to recycle important nutrients back into agricultural systems in response to these issues. These eco-friendly techniques for turning trash into nutrient-rich fertilizers, improving soil health, and lowering greenhouse gas emissions include composting, anaerobic digestion, biochar synthesis, vermicomposting, and microbial-based recovery. A comparison of these methods reveals their economic viability, environmental impact, and efficacy. Successful implementation and the advantages of implementing circular agriculture methods are illustrated through case studies and real-world applications. With an emphasis on the necessity of innovation and integrated approaches to sustainable nutrient management, the chapter ends with insights into the difficulties, policy issues, and hopes for nutrient recovery in the future. Agricultural systems can move toward a more resilient and circular model by putting eco-safe nutrient recovery technology into practice. This will reduce waste, enhance soil health, and lessen environmental concerns. This chapter examines several environmentally friendly nutrient recovery methods, emphasizing their workings, advantages, and uses in sustainable farming. Farmers may increase crop productivity, reduce their negative effects on the environment, and stop the nutrient loop by implementing these techniques. Furthermore, incorporating these technologies into agricultural systems promotes long-term food security, resource conservation, and climate change mitigation. Cost, scalability, and farmer adoption are still obstacles in the way of their potential. In order to ensure a sustainable and resilient agricultural future, this study highlights the necessity of policy assistance, education, and innovation to encourage the broad adoption of eco-safe nutrient recovery technology.
