A multi-KET (key enabling technologies) approach is most beneficiary for SME in regard to increase in productivitiy, efficiency and market shares. To enable a Pan-European Access for SME on technology services for clean production, a network of premier KET Technology Centres with facilitated one stop shop access, offering SME multi-ket infrastructures and services across borders on pan-european level is generated, involving innovation consultants from the Enterprise Europe Network (EEN) being local = at the doorstep of EU`s manufacturing SMEs. Due to the disparity of KET TC in EU28, KET4CleanProduction (KET4CP) enables also a discourse with policy makers on RIS3 and the potential of cross-border collaboration to cover specific SME needs for clean production technologies. KET4CP starts with 12-premier KET TC and 7 EEN as an open innovation ecosystem, with a one stop shop access. KET facilitators support the SME in identifying their specific technology challenge for clean production, propose services and technologies based on innovation potential + need analysis. The fast, flexible services focus on the SME´s business case. After a pilot phase with 20 SME innovation projects/micro grants, the network is scaled up adding 17 KET TC and 21 EEN members, to reach a critical mass of CP technology deployment in SME. Targeted actions stimulate initial requests of >120 SME from > 10 EU MS and a total of 70 SME micro grant projects with min. 140 KET TC. 2 MEUR third party financing go to SME in total. 50 % are targeted for low to modest innovator regions. KET4CP delivers standard procedures / tools for KET TC transnational collaboration and joint service/shared infrastructure, based on business model scenarios stimulating KET TC to collaborate and share clients. KET4CP creates a sustainable platform, a win-win situation for all stakeholders with a high potential for scale up. The aim for 2022 is to have 100 KET TC and 180 EEN members with 1000 SME inquiries p.a.
