The Alps4GreenC project is focused on setting-the-scene for transnational utilization of biomass residues through investigation of biomass conversion opportunities in project partner countries and proposal of transnational biochar-based value chains. As such, we are tackling the challenges of the Alpine area pertaining to adverse effects of energy dependency and high energy prices, biodiversity losses and high vulnerability to climate change, while offering solutions for the use of greatly available biomass in the region. By proposing the necessary supportive measures through policy recommendations and practical testing and pilot production of green carbon to evaluate the potential of its utilisation for steel and agriculture industry, we will contribute towards creating the conditions for energy sufficiency and climate-protection of the region showcasing the innovation and resource potentials already present, but currently disconnected. The advantages of this transnational collaboration will be primarily experienced by those directly involved in the value chain (residue producers, tech providers and end users, hence large enterprises and SMEs), however other stakeholders in the ecosystem, such as national/regional public authorities, sectoral agencies and higher education and research organisations, will also benefit from comprehensive framework creation. The framework we propose includes mapping of stakeholders & resources, implementation of crowdsourcing campaign to collect biomass residues and raise awareness, testing and piloting of biochar and context & gap analysis of biomass conversion opportunities for green carbon supply. Without a transnational approach to this issue, appropriate technologies for biomass conversion will not be identified and upgraded, therefore the shift to green, post-carbon approaches might not be fully realised. It is the first time, transnational collaboration for the establishment of biochar production value chain is foreseen.
