KOUTRETSOS KONSTANTINOS

Their core work

KOUTRETSOS KONSTANTINOS (trading as 3DHUB) is a Greek private company operating in the secondary raw materials and critical metals recovery space. Their project participation points to practical expertise in processing and recovering precious and platinum-group metals from end-of-life industrial products — specifically spent automotive catalysts, WEEE, photovoltaic panels, and printed circuit board assemblies. The "3DHUB" branding suggests a possible additive manufacturing or advanced fabrication capability that feeds into their recovery or prototyping work within circular economy consortia. They function as a specialist industrial contributor, bringing hands-on processing or technology know-how to large research and pilot-scale projects rather than leading them administratively.

What they specialise in

How they've shifted over time

KOUTRETSOS KONSTANTINOS entered H2020 participation through FENIX (2018-2021), a project concerned with business models and supply chain structures for industrial secondary resource recovery — a relatively broad, systems-level framing with no highly specific technical keywords attached to their contribution. By their second project, PEACOC (2021-2026), the focus had narrowed sharply to a defined materials class: precious and platinum-group metals from automotive catalysts, WEEE, photovoltaic panels, and circuit boards. This shift from broad resource recovery framing toward specific high-value critical raw materials is a clear progression, and it aligns with growing EU policy pressure around critical raw materials supply chains.

This organisation is moving deeper into critical raw materials recovery — specifically the platinum-group metals segment — which is one of the highest-priority areas in the EU's Critical Raw Materials Act and Green Deal industrial strategy, suggesting strong positioning for future calls in this space.

How they like to work

KOUTRETSOS KONSTANTINOS has participated exclusively as a consortium partner across both projects and has never held a coordinator role, indicating they are a technical or operational contributor rather than a project manager. Despite their small project footprint (2 projects), they have worked with 28 unique partners across 11 countries, which points to integration into broad, multi-stakeholder consortia rather than tight bilateral collaborations. This suggests they are valued for a specific, repeatable capability that consortium builders seek out.

Their network spans 28 unique partners across 11 European countries, built entirely through two large consortia projects in the manufacturing and environment sectors. The reach is genuinely European despite the small project count, suggesting their consortia were geographically diverse industry-led or multi-actor initiatives.

What sets them apart

KOUTRETSOS KONSTANTINOS occupies an unusual niche as a Greek private company with hands-on involvement in two consecutive EU-funded precious metals recovery projects — a domain dominated by large research institutes and smelting corporations. Their "3DHUB" identity hints at advanced fabrication or prototyping capabilities that may bridge material processing with digital manufacturing, a combination rare among pure recycling actors. For a consortium building around critical raw materials recovery pilots, they offer a private-sector, implementation-oriented perspective from a Southern European context that is often underrepresented in this sector.

Highlights from their portfolio

• FENIX
  Their entry project (2018-2021) with the largest single funding award (EUR 173,094), focused on business model innovation for secondary resources — showing early involvement in circular economy systems thinking, not just technical processing.
• PEACOC
  A pre-commercial pilot (2021-2026) targeting recovery of platinum-group metals from WEEE, automotive catalysts, and photovoltaic panels — one of the most commercially and strategically significant materials recovery domains in current EU industrial policy.
