About this Research Topic
With the focus on circular economy comes development of new processes for nutrient recovery from wastes and hence new fertilizer products expected to substitute conventional mineral fertilizers. What will make farmers and growers adapt these new fertilizer products that everybody envisions in a circular economy future?
So far most researchers, clean-tech providers and operators assume that as long as we come with an innovative waste processing technology, an interesting new technique or a novel fertilizer product, then there will be a market for these – but that is not at all certain!
Therefore we need more research into what properties, barriers and advantages that farmers and growers would regard as key for them to embrace the circular economy and adapt recycled fertilizer products over conventional mineral counterparts.
This Research Topic welcomes surveys and more detailed research on preferences and priorities amongst primary end-users of these products (farmers and growers in various sectors), growing conditions and market environments, but also studies into the choices and decision-making of secondary end-users (food-processing companies, retailers and ultimately consumers).
Other sub-topics include aspects related to impacts of recycling, bio-based fertilizer products on yield, product quality and measures of mineral fertilizer replacement value, as well as short- and long-term impacts on soil fertility and quality, including soil organic matter, carbon sequestration etc.; or aspects related to recycling, bio-based fertilizer quality measures, and various frameworks for quality certification.
Keywords: circular economy, nutrient recovery, waste, fertilizer, farmers, growers, waste processing technology, recycled fertilizer products, bio-based fertilizer, soil fertility, organic matter, carbon sequestration, quality certification, mineral fertilizers
