Synergy of eco-innovation with on-farm practices enhances circularity beyond conventional nutrient recovery framework.

• Nutrient recovery shifts to the 3Rs (reduce, reuse, recycle) from a linear model. • 3Rs highlight significant loss efficiency in current nutrient recovery models. • On-farm circularity is pivotal to address nutrient loss in recovery frameworks. • Eco-innovations accentuate low-carbon footprints in on-farm circularity. • Eco-innovation‒on-farm practices synergy redefines nutrient recovery sustainably. The escalating challenges of resource scarcity and environmental degradation in agroecosystems necessitate innovative strategies for sustainable nutrient management. This review explores the integration of circular economy principles into nutrient recovery frameworks, emphasizing eco-innovative technologies that promote sustainability and resilience in agricultural practices. By examining various on-farm circularity practices and their efficacy in nutrient recovery, we highlight the potential of nature-inspired solutions such as constructed wetlands and algae-based systems to reduce environmental impacts and enhance nutrient use efficiency. The findings advocate for a paradigm shift towards advanced nutrient management strategies that leverage eco-innovation to reduce greenhouse gas emissions, optimize resource use, and align with global sustainability goals. The adoption of these strategies can significantly contribute to the sustainable transformation of the agricultural sector. [Display omitted] [ABSTRACT FROM AUTHOR]
