Pitch to Us: Industrial Side-Streams to High-Value Materials

​Are you turning industrial waste streams into high-value materials? We'd like to hear about it.

​On May 21st, Marvelous is opening the floor to founders working on industrial side-stream valorization — for a focused, 30-minute pitch session in front of our General Partners and a room of LPs and corporate innovation executives from Europe's leading deep tech companies.

​This is a curated, invite-only session, and we want to hear from you. We invest at Pre-Seed and Seed in science-based, hardware-driven startups with patentable IP. If your technology is redefining what industrial waste means for heavy industry or the built environment — let's talk!

​♻️ What we're looking for:

​→ Technologies that convert industrial side-streams into materials, chemicals, or energy — with novel chemistry, biology, or process engineering

​→ Science-based approaches with defensible IP — not business models or software

​→ Founders building for industrial scale (TRL 3–8) with an identifiable industrial offtaker

​→ In-scope:

​CO₂ / flue gas valorization

​· steel slag, fly ash & mine tailings

​· battery, PV & wind blade recycling

​· chemical plastics recycling

​· industrial wastewater recovery

​· C&D waste to low-carbon materials

​🎙️ In the room: Marvelous General Partners + LPs and innovation executives from Deep Tech Momentum

​📍 Wilhelm Studios Berlin | Catalyst Lab Room

​🗓️ 21 May 2026 | 15:45 – 16:15 CEST

​Spots are extremely limited.
