Frass to Future: How Nasekomo and Siemens Are Scaling Soil Regeneration with Black Soldier Fly Tech

In this interview recorded at Hannover Messe, Marc Bolard, co-founder and CEO of Nasekomo, and Rok Koren, Senior Digitalization Advisor at Siemens Slovenia, explain how black soldier fly bioconversion is being scaled with industrial technology to address soil degradation and food security. Nasekomo, a scale-up headquartered in Sofia, Bulgaria, uses black soldier flies to convert organic waste into frass — a biologically rich organic fertilizer that helps regenerate depleted soils and restore their ability to capture carbon. Marc outlines the core problem: decades of intensive agriculture have stripped soils of essential nutrients, measurably reducing the nutritional content of food crops and contributing to declining healthy life expectancy. Research cited in the conversation references a University of Texas at Austin study showing significant nutrient loss across 43 crops over 50 years. Frass to Future, Nasekomo's recently introduced platform, offers a circular-as-a-service model through which businesses can support soil regeneration via a monthly subscription. The approach enables frass production at scale while providing data-backed traceability on carbon and nutrient outputs for every tonne of food produced. Rok Koren describes how the collaboration with Nasekomo began four years ago and has since become an award-winning partnership — incorporating elements of the Siemens Xcelerator portfolio across Nasekomo's production processes. Digitalization, automation, and data accountability are central to the joint work, with AI identified as a future area of development. The conversation also addresses Nasekomo's projects in desert environments, including the Middle East, where organic fertilization is being used to restore soil fertility and support local food production. Marc highlights food sovereignty as a growing priority in regions where global supply chain disruptions have increased dependence on food imports. Both guests emphasize the importance of open, trust-based partnership as a foundation for developing sustainable industrial solutions at a meaningful scale.
