From Space Tech to Sustainable Farms: How German Startups are Reinventing Fertilizer
As farmers prepare for the spreading season, a critical challenge remains: balancing the need for effective fertilization with the environmental impact of traditional manure application. Gülle – or slurry – while rich in essential nutrients, similarly releases harmful greenhouse gases like ammonia and methane. But a novel wave of innovation, spearheaded by German startups like Nunos GmbH, is promising a solution: turning waste into a valuable, eco-friendly resource.
The Problem with Traditional Manure
The agricultural sector is a significant contributor to greenhouse gas emissions. According to figures from the German Federal Environment Agency, approximately two-thirds of Germany’s agricultural emissions stem from livestock farming – representing 5.3% of the country’s total greenhouse gas output. Much of What we have is linked to the release of methane and ammonia from manure. These emissions not only contribute to climate change but also negatively impact air and water quality.
Nunos: A Space-Age Solution for a Down-to-Earth Problem
Nunos, a startup originating from the German Aerospace Center (DLR), has developed a process to transform manure into a more efficient, odorless fertilizer. The technology, initially conceived for cultivating plants in space – specifically, recycling human urine for use in space station greenhouses – has found a powerful application on Earth.
The Nunos system utilizes a purely biological process, employing microorganisms within a 24-hour cycle to convert manure into a fertilizer with enhanced nutrient utilization and significantly reduced greenhouse gas emissions. This results in both a liquid fertilizer solution, rich in readily available nutrients, and a solid fertilizer with a high organic substance content.
How Does it Work?
The key lies in optimizing nutrient availability. The new fertilizer formulation ensures that nutrients reach plants more quickly and efficiently than with conventional manure spreading, minimizing losses through leaching into the soil. Early plant trials suggest potential yield increases of up to 20%, a figure Nunos plans to validate through field trials on two farms in 2026.
DBU Funding and the Future of Circular Agriculture
The Deutsche Bundesstiftung Umwelt (DBU) is supporting Nunos with €125,000 in funding, recognizing the company’s innovative approach to sustainable agriculture. This funding will enable Nunos to conduct more comprehensive environmental impact assessments and further refine its technology. The DBU supports founders developing innovative and economically viable solutions for the environment, ecology, and sustainability.
Beyond the Farm: Fertilizer for Home Gardeners
Nunos isn’t just targeting large-scale agricultural operations. The company also produces smaller quantities of its fertilizer for home use, marketing it as a “multivitamin drink” for plants, suitable for tomatoes and houseplants. This direct-to-consumer approach, facilitated through online sales, expands the reach of this sustainable technology.
Patent Protection and Expansion Plans
The manure conversion process is patented through the DLR and exclusively licensed to Nunos, securing its competitive advantage. Currently, the company focuses on processing cattle manure and digestate from biogas plants. The DBU funding will allow for more extensive testing of the environmental impacts and further optimization of the process.
