Novaleum raises €1M seed for grease-waste-to-biofuel NovaBOX

What's the deal? Lyon-based startup NovaleumDealroom has a profile for this one. Try Dealroom → has closed a €1M funding round to develop its NovaBOX — a modular unit that transforms grease waste into new resources, including biofuel. The company was co-founded by Ulrich Darbost, Bastien Mettra, Isabelle Bonnamour, and Yann Gillard.

Why now? The push toward circular economy solutions and sustainable fuel alternatives is intensifying across Europe. Waste-to-energy technologies are attracting growing interest as regulators tighten rules on industrial waste disposal and fossil fuel use.

What could go wrong? Modular waste-processing technology must clear significant regulatory and technical hurdles before commercial deployment. Scaling from prototype to reliable industrial product is notoriously difficult for hardware startups, and €1M is a modest war chest for that journey.

The signal: Novaleum's €1M raise, while modest, marks an early growth-stage bet on a niche that European waste regulations are rapidly expanding. With grease waste management still largely handled by conventional disposal methods, a modular, on-site conversion unit could appeal to industrial operators facing rising compliance costs — provided the startup can bridge the gap from prototype to proven product.
