Porelio, a Germany-based deeptech company specializing in advanced materials for industrial separation and water treatment, has secured €2.4 million in a pre-seed funding round. The oversubscribed round was led by Faber, with participation from Polytechnique Ventures, Grupo Tecnológica, and better ventures.
The startup has developed a proprietary continuous-flow manufacturing process for Functionalized Ordered Mesoporous Silicas (FOMS), materials designed to capture industrial pollutants and recover valuable resources more effectively than conventional methods. The technology addresses two critical industrial challenges: the removal of persistent organic pollutants like PFAS from water supplies and the recovery of precious metals from manufacturing waste streams.
Scaling Laboratory Success to Industrial Applications
Porelio was founded in 2025 with the explicit mission of bringing materials science innovation from the laboratory to practical industrial scale. According to the company’s co-founder Dr Rhea Machado, the underlying chemistry represents decades of academic research that remained largely unrealized at meaningful production volumes.
“This chemistry has sat on laboratory benches for thirty years. Everyone could see its potential; no one had made it at the scale that matters,” Machado stated. “A material that works by the gram cannot clean a contaminated water supply nor recover the metal lost in an industrial stream. We solved the scale, so it can finally do that work.”
This perspective captures a common challenge in the deeptech sector: the gap between theoretical advances and commercially viable production. Porelio’s approach targets this specific bottleneck through its manufacturing innovation rather than fundamental material discovery.
Funding to Drive Production Expansion
The newly raised capital will support three primary objectives. First, the company plans to accelerate its technology development efforts. Second, the funding will finance the scaling of FOMS material production from pilot-scale facilities to industrial-capacity manufacturing. Third, Porelio intends to convert existing collaborations with industrial partners into formal commercial agreements and revenue-generating contracts.
The presence of Faber as lead investor reflects growing institutional confidence in materials science solutions to environmental and industrial challenges. The inclusion of Polytechnique Ventures, the venture arm of one of France’s leading engineering schools, suggests academic validation of the underlying technology.
European Cleantech Momentum
Porelio’s funding round arrives amid increasing European investment in industrial decarbonization and environmental remediation technologies. Water treatment and resource recovery represent priority areas across European regulatory frameworks, particularly following heightened scrutiny of PFAS contamination and industrial metal waste management. The startup’s emergence from Germany positions it within Europe’s established strength in chemical engineering and industrial process innovation.
As water quality regulations tighten and industrial sectors face mounting pressure to adopt circular economy practices, companies offering scalable, efficient separation technologies occupy an advantageous market position. Porelio’s pre-seed success suggests that investors increasingly view materials engineering solutions to industrial environmental challenges as viable venture investments rather than purely academic pursuits.
