  Biochar pilots

  Type of output:Download

  The CSC (A1.1) collected the interests of 22 companies from SI, AT, and IT, A methodology for residue selection, analyses, lab tests, pilot tests, and biochar analyses was developed. Based on the criteria, 10 residues were selected and lab-tested via gasification or pyrolysis, and 2 were pilot-tested. Transnational cooperation facilitated the transfer of know-how on optimal operating conditions, resulting in a comprehensive analysis of 12 biochar samples, indicating potential use in agriculture and the steel industry. Certificates of analysis were prepared for residue providers, detailing biomass residue analysis, conversion technology, biochar analysis results, and application potential. The CSC demonstrated that numerous biomass residues are suitable for biochar valorization via pyrolysis or gasification. Project results showed that different residues and their biochars suit various applications. The performance of produced green carbon is presented in a library of 12 samples available on an open platform repository, extending the European mapping of lignocellulosic residues. This repository provides analytical results for all 10 residues and 12 biochars. Certificates for the ten CSC participants and D1.3.1 are available. In A1.2, an interactive Alps4GreenC map was developed, to categorize economic activities related to biomass residue supply chains across Europe. Using a comprehensive methodology, Eurostat data was utilized to identify and prioritize relevant companies and economic activities. Stakeholders within the supply chain were considered, aiding the categorization of economic activities at national and regional levels.

  Alps4GreenC Policy recommendations

  Type of output:Download

  Biochar and green carbon from biomass residues can reduce the energy dependency of the Alpine region, improve climate resilience and protect biodiversity. Understanding regulatory and policy framework is essential for participation in the green carbon supply chain. IT, SI and AT are leading the way in their efforts, characterised by their unique political, financial and environmental landscape. The Alps4GreenC policy recommendations are the result of collaboration between the partners and focus on the opportunities for biomass conversion for green carbon supply. Based on data from two structured questionnaires and supported by biochar experts from SI and DE, highlight legal, socio-cultural, political, economic and geographical factors that influence biomass conversion initiatives and serve as a catalyst for informed decision-making. The success of biomass conversion depends on strategic planning and support. Understanding geographical, climatic and logistical factors combined with proactive policies and financial incentives is critical to the growth and integration of biomass solutions in IT, SI and AT. By addressing knowledge gaps, creating incentives and advocating for supportive policies, these countries aim to promote biochar technologies that contribute to sustainable practises, environmental protection and benefits such as improved soil health and carbon sequestration. Best practises in biochar production across the Alpine region demonstrate innovative and sustainable solutions, such as Sonnenerde’s garden applications, Nawaro Energie’s biomass plant, Humus+’s soil improvement project, Vulkanland’s biomass heating and Energiwerk Ilg’s sustainable road surfacing. CORC’s co-operation model, AquaGreen’s conversion of wet sewage sludge and various projects in SWE and DE show the versatility of biochar. LOIs were signed to support the implementation of recommendations to promote the use of biochar and encourage sustainability in the Interreg Alpine Space region.
