Stichting Innovatie Glastuinbouw Nederland

What Stichting Innovatie Glastuinbouw Nederland does

Stichting Innovatie Glastuinbouw Nederland (SIGN) is an independent Dutch foundation (Stichting) established in 1997-1998 by prominent greenhouse growers to drive strategic innovation in the Dutch greenhouse horticulture sector. The organization operates Living Lab Bleiswijk, a physical facility where entrepreneurs, researchers, students, and designers collaborate on pilots and demonstrations covering circular horticulture, organic substrates, water purification using plants, air purification, biocircular packaging, biobased materials, and sustainable housing for seasonal workers. SIGN executes multi-year innovation programs — notably the completed Innovatieprogramma Circulaire Glastuinbouw 2020-2026 and the new 'drievoudige waardecreatie' (triple value creation) program launched in 2026 — funded through co-financing from the Dutch Ministry of LVVN (formerly LNV) and partnerships with Glastuinbouw Nederland, VBN, and regional Greenports.

SIGN has approximately 6 employees and generates no commercial revenue; its economic model is a public-private sector innovation intermediary, distributing knowledge, validated research findings (e.g., TNO-validated air purification, 38-week tomato substrate trials matching rock wool performance), and practical toolkits such as the Tuinbouw Experience Draaiboek to growers, policymakers, and the broader public. Its go-to-market is community-led rather than commercial, relying on Living Lab convening, publications, and events such as the Biomass Heroes conference to disseminate outcomes. Technology partnerships with research institutions (Vertify, Hogeschool Inholland, TNO) and industrial suppliers (Van der Knaap, Vivent Biosignals) provide the technical execution layer beneath SIGN's programmatic mandate.

It operates in the same Dutch regional context as SIGN and supports similar innovation ecosystems, including greenhouse horticulture clusters, making it a peer in regional innovation facilitation.
• BioBoost Platform: BioBoost is a Dutch platform coordinating biobased innovation initiatives. SIGN explicitly references BioBoost as a hub for ongoing circular horticulture initiatives, making it a closely adjacent peer in the Dutch biobased and circular economy ecosystem.

Direct peers

• Foodvalley NL: Foodvalley NL is a Dutch innovation network focused on sustainable food systems. Like SIGN, it convenes entrepreneurs, researchers, and government to drive innovation in food and agriculture. Both act as ecosystem orchestrators rather than product companies, with overlapping geographic focus on the Netherlands and shared sustainability themes.

Broad incumbents

• Wageningen University & Research: Wageningen University & Research is the leading Dutch agricultural research institution and a key knowledge partner for SIGN. While SIGN focuses on practical Living Lab pilots with entrepreneurs, Wageningen conducts the underlying scientific research. Both address circular horticulture and sustainable cultivation, making Wageningen a strategic upstream peer.

Others

• Holland Bio: Holland Bio is the Dutch biotech industry association. While SIGN focuses on agriculture/horticulture rather than biotech specifically, both serve as Dutch sectoral intermediation organizations convening public and private stakeholders around life-science innovation, making Holland Bio a thematic peer.
• Groen Kennisnet / Wiki Circulaire Tuinbouw: Groen Kennisnet is the Dutch knowledge platform for the green sector and hosts SIGN's WIKI Circulaire Tuinbouw. It serves as a complementary knowledge-distribution layer for SIGN's research outputs, making it an adjacent ecosystem participant rather than a direct peer.
