During the TRIS project IFKA identified the green public procurement (GPP) as a relevant tool to promote industrial symbiosis and circular economy business models.

Sustainable and strategic use of public procurement is also increasingly in the focus of European Union policies to achieve the Europe 2020 objectives of smart, sustainable and inclusive growth.

Therefore, IFKA participated in a Horizon 2020 financed project to get know more about the European and also the Hungarian GPP situation.

The main output was a Design Option Paper (DOP). The document:

- details the importance of GPP and its variants based on the information available in publications;
- highlights the links between Smart Specialization Strategy (S3) and the green public procurements for innovation 
- includes the analysis of good practices identified during the project; 
- summarises the findings that comes from the meetings with local working groups (LWG) and key stakeholders 
- presents common challenges and lessons learned from previous projects – like TRIS 
- makes recommendations. 

IFKA reviewed many policies, methodologies, good practices – even the ones learned within TRIS - and experiences to collect relevant information and summarized them in the document. In addition, 3 LWG meetings were organized continuing and monitoring the work done during TRIS project in this respect: involving policy makers, public authorities responsible for the development, preparation and management of public procurement, purchasers and stakeholders involved in supporting the green economy and innovation for SMEs.

The aim was to gain more knowledge from the experts and identify the main challenges, problems and opportunities to progress in the future.
