WIEDEMANN GMBH

Their core work

Wiedemann GmbH is a German SME that specializes in materials processing and waste valorization, contributing technical expertise to EU research consortia focused on converting organic waste streams into useful products. Their project portfolio shows capabilities spanning from nanomaterial applications in construction and heritage conservation to biowaste conversion into biopolymers and biofertilizers. The company appears to operate at the intersection of materials science and circular bioeconomy, bringing practical industrial know-how to large research-driven consortia.

What they specialise in

How they've shifted over time

Wiedemann's trajectory shows a clear shift from advanced materials for the built environment toward circular bioeconomy applications. Their earliest project (NANO-CATHEDRAL, 2015) focused on nanomaterials for heritage building conservation — a niche manufacturing application. By 2016, with VOLATILE, they pivoted toward biowaste processing and bio-based chemicals, and their most recent project (RUSTICA, 2021) is squarely in circular agriculture, converting fruit and vegetable waste into biofertilizers. The common thread is materials transformation, but the application domain has moved decisively from construction to food-system circularity.

Wiedemann is moving toward circular bioeconomy and agricultural waste valorization, making them a relevant partner for future projects on organic waste reuse, bio-based fertilizers, and food-system sustainability.

How they like to work

Wiedemann operates exclusively as a consortium participant, never as coordinator, which is typical for a specialist SME contributing targeted technical capabilities to larger research efforts. With 54 unique partners across just 3 projects, they work in large consortia (averaging 18+ partners per project), indicating comfort with complex multi-partner environments. Their role pattern suggests they are brought in for specific industrial expertise rather than driving project strategy.

Despite only 3 projects, Wiedemann has built a broad network of 54 unique partners spanning 14 countries, reflecting the large-consortium nature of their Innovation Action and Research projects. Their reach is genuinely pan-European with no obvious geographic clustering.

What sets them apart

Wiedemann brings an unusual combination: industrial materials processing expertise applied to both traditional sectors (construction heritage) and emerging bioeconomy applications. For consortium builders, their value lies in being a hands-on SME capable of translating lab-scale bio-based processes into practical implementation, particularly in waste-to-product pathways. Their participation in both IA and RIA projects suggests they can contribute to both fundamental research and near-market demonstration.

Highlights from their portfolio

• VOLATILE
  Largest single grant (€208K) and a bridge project linking biowaste chemistry to biopolymer production — the pivot point in Wiedemann's shift toward bioeconomy.
• RUSTICA
  Most recent project (2021-2024) focused on demonstration-scale circular biofertilizers, signaling their current strategic direction in agricultural waste valorization.
• NANO-CATHEDRAL
  Earliest H2020 project showing their original materials science roots — nanomaterials applied to European architectural heritage conservation.
