Fritsche F, Brunori G, Chiaramonti D, Galanakis C, Matthews R, Panoutsou Cet al., 2021, Future transitions for the Bioeconomy towards Sustainable Development and a Climate-Neutral Economy - Bioeconomy opportunities for a green recovery and enhanced system resilience., Publisher: European Union

The COVID-19 pandemic is causing an unprecedented global health crisis and socio-economic upheaval and led to severe consequences well beyond previous crises of the last decades which mostly were related to financial issues. COVID-19 caused sudden economic, psychological, and partly physical shocks to markets, societal sub-systems (e.g., education, food, health), and people.As a direct consequence, today, food security and resilience are at stake. The effects on bio-based products and bioenergy (in particular: biofuels) vary and their role in the recovery (with possible changes in customer’s behaviour) could differ as well.The linkages of the bioeconomy to post-pandemic recovery with regard to impacts and possible responses are currently being discussed by many institutions and initiatives, even though there is currently limited data on the impact of the pandemic on the bioeconomy. This report presents preliminary results based on initial analysis from the authors on knowledge synthesis on the EU bioeconomy system, trends, and perspectives of the future development towards 2030 and 2050.

Fritsche U, Brunori G, Chiaramonti D, Galanakis C, Matthews R, Panoutsou Cet al., 2021, Future transitions for the Bioeconomy towards Sustainable Development and a Climate-Neutral Economy - Foresight Scenarios for the EU bioeconomy in 2050., Publisher: Publications Office of the European Union

The 2018 EU Bioeconomy Strategy aims to develop a circular, sustainable bioeconomy for Europe, strengthening the connection between economy, society, and environment. It addresses global challenges such as meeting the Sustainable Development Goals (SDGs) set by the United Nations and the climate objectives of the Paris Agreement. A circular, sustainable bioeconomy can be a core instrument for the Green Deal in the post-COVID-19 era, making the EU more sustainable and competitive. In this context, the EC (Joint Research Centre in collaboration with DG Research and Inno-vation) created an ad-hoc external Network of Experts (NoE) through individual contracts to contribute to the EC’s Knowledge Centre for Bioeconomy with forward-looking analysis needed for exploring possible scenarios towards a sustainable, clean, and resource-efficient bioeconomy, with a focus on climate-neutrality and sustainable development. The first work package concerned knowledge synthesis and foresight. This report presents the results of a collaborative foresight process which elaborated four scenarios for the future EU bioeconomy until 2050: Scenario 1: Do it for us - proactive policy, Paris target nearly achieved (2 °C global temperature increase by 2100), no societal change (Business As Usual trend for consumption) Scenario 2: Do it together – integrative policy, Paris target fully achieved (1.5 °C global temp. increase by 2100), fundamental societal change (towards sustainable consumption) Scenario 3: Do it ourselves - societal action, Paris target missed (global temperature increase 2.5 °C by 2100), fundamental societal change (towards sustainable consumption) Scenario 4: Do what is unavoidable - reactive policy, Paris target clearly missed (3.5 °C global temperature increase by 2100), no societal change (Business As Usual trend for consumption) Finally, this report presents initial reflections on transition pathways gained from these scenarios in 2050, and insi

Panoutsou C, Germer S, Karka P, Papadokostantakis S, Kroyan Y, Wojcieszyk M, Maniatis K, Marchand P, Ingvar Let al., 2021, Advanced biofuels to decarbonise European transport by 2030: markets, challenges, and policies that impact their successful market uptake, Energy Strategy Reviews, Vol: 34, ISSN: 2211-467X

Advanced biofuels are among the available options to decarbonise transport in the short to medium term especially for aviation, marine and heavy-duty vehicles that lack immediate alternatives. Their production and market uptake, however, is still very low due to several challenges arising across their value chain. So far policy has established targets and monitoring frameworks for low carbon fuels and improved engine performance but has not yet been sufficient to facilitate their effective market uptake. Their market roll-out must be immediate if the 2030 targets are to be met. Analysis in this paper reiterates that the future deployment of these fuels, in market shares that can lead to the desired decarbonisation levels, still depends largely on the integration of tailored policy interventions that can overcome challenges and improve upstream and downstream performance. The work presented aims to i) inform on policy relevant challenges that restrict the flexible, reliable and cost-efficient market uptake of sustainable advanced biofuels for transport, and ii) highlight policy interventions that, have strong potential to overcome the challenges and are relevant to current policy, Green Deal and the Sustainable Development Goals (SDGs).

This paper gives an overview of development of the EU-bioeconomy, 2014-2020. The Vision of the new Circular Bio-based Economy, CBE is presented: Unlocking the full potential of all types of sustainably sourced biomass, crop residues, industrial side-streams, and wastes by transforming it into value-added products. The resulting product portfolio consists of a wide spectrum of value-added products, addressing societal and consumer needs. Food and feed, bio-based chemicals, materials, health-promoting products; and bio-based fuels. The pillars of CBE are described, including biotechnology, microbial production, enzyme technology, green chemistry, integrated physical/chemical processing, policies, conducive framework conditions and public private partnerships. Drivers of CBE are analyzed: Biomass supply, biorefineries, value chain clusters, rural development, farmers, foresters and mariners; urgent need for climate change mitigation and adaptation, and stopping biodiversity loss. Improved framework conditions can be drivers but also obstacles if not updated to the era of circularity. Key figures, across the entire BBI-JU project portfolio (2014–2020) are provided, including expansion into biomass feedstocks, terrestrial and aquatic, and an impressive broadening of bio-based product portfolio, including higher-value, health-promoting products for man, animal, plants and soil. Parallel to this, diversification of industrial segments and types of funding instruments developed, reflecting industrial needs and academic research involvement. Impact assessment is highlighted. A number of specific recommendations are given; e.g., including international win/win CBE-collaborations, as e.g., expanding African EU collaboration into CBE. In contrast to fossil resources biological resources are found worldwide. In its outset, circular bio-based economy, can be implemented all over, in a just manner, not the least stimulating rural development.

Singh A, Christensen T, Panoutsou C, 2021, Policy review for biomass value chains in the European bioeconomy, Global Transitions, Vol: 3, Pages: 13-42, ISSN: 2589-7918

The main aim of this paper is to review existing European policies relevant to the biomass value chains and examine how their main objectives support or align with the five core objectives (pillars) identified under the 2018 Bioeconomy Strategy. The paper also discusses key challenges that restrict the compliance of the policies to the Strategy, identifies policy gaps and provides recommendations for future policy formation.A structured review was conducted of over ninety policies relevant to the biomass, bioprocessing and biobased products. The value chain approach was used as a tool to harmonise these sectors under a common bioeconomy framework and provides an understanding of how key activities and challenges are being addressed. Several gaps were identified in relation to these challenges in each stage, at land use stage a lack of European-wide harmonised characterisation of marginal land and integration among sectoral policies targeting soil quality and financial measures incentivising the uptake of sustainable soil improvers. At the biomass production stage, inadequate policy support was found for waste mobilisation and valorisation. Furthermore, there is a lack of policy provisions and financial support improving collaborations among value chain actors to overcome the complexity associated with harmonising biomass logistics and conversion processes. Finally, regarding the end use stage, policy interventions targeting the distribution and standardisation of the wide, available range of biobased products and services remain limited. Based on this gap analysis, a set of recommendations was produced outlining ways in which policy measures can be updated through introducing either financial, regulatory or information provisions, or formulating novel policies altogether. These recommendations were made following the value chain analysis approach, which addresses specific challenges in relation to the five core objectives of the Bioeconomy Strategy, with the aim of

Singh A, Christensen T, Panoutsou C, 2020, Policy review, gaps and recommendations for value chain challenges in the EU Bioeconomy, Global Transitions, ISSN: 2589-7918

Aim of this paper is to review existing European policies relevant to the bioeconomy and examine how their main objectives support or align with the five core objectives under the 2018 Bioeconomy Strategy as well as key challenges in biomass value chain stages to identify policy gaps and produce set of recommendations. A structured review of over ninety policies relevant to the bioeconomy was conducted by value chain stage and provided an understanding of how key activities and challenges within biomass value chains are being addressed. Several gaps were identified in relation to these challenges in each stage, including a lack of European-wide harmonised characterisation of marginal land, integration among sectoral policies targeting soil quality and financial measures incentivising the uptake of sustainable soil improvers. At the biomass production stage, inadequate policy support was found for waste mobilisation and valorisation. Furthermore, there is a lack of policy provisions and financial support improving collaborations among value chain actors to overcome the complexity associated with harmonising biomass logistics and conversion processes. Finally, regarding the end use stage, policy interventions targeting the distribution and standardisation of the wide range of biobased products and services remain limited. Based on gap analysis, recommendations were produced outlining ways in which policy measures can be updated through introducing additional provisions, or formulating novel policies altogether. Recommendations were made following the value chain analysis approach, which addresses specific challenges in relation to the five core objectives with the aim of increasing the level of coherence among sectoral policies.

Panoutsou C, Singh A, 2020, A value chain approach to improve biomass policy formation, GCB Bioenergy, Vol: 12, Pages: 464-475, ISSN: 1757-1693

Biomass value chains for energy, fuels and bio‐based products involve complex, cross sector interactions between their upstream and downstream stages. Overarching policymaking to date has included the use of biomass to deliver sector specific aims (e.g. climate change, energy, etc.) however, this is mostly planned without adjusting support across the most challenging stages of biomass value chains and exploiting specific advantages related to their geographic settings (e.g. domestic feedstocks, local markets, etc.). Policies to date have, therefore, resulted in fragmented, suboptimal biomass use and debates for sustainability and resource efficiency. This opinion paper arose from the project Strategic Initiative for Resource Efficient Biomass Policies Funded by the EU Commission. It discusses the development of a dedicated Biomass Policy Framework which applies the principles of value chain analysis in policy design to enable the market uptake of sustainable, domestic, resource efficient biomass solutions. Firstly, it explains how to provide context by identifying value chains which can offer competitive advantages for biomass mobilization, market infrastructures, rural and economic development within their geographic setting. Then the work builds on the context and prioritized value chains and further rationalizes policy needs and aims within individual value chain stages. This is done by identifying policy‐related challenges and gaps that constrain sustainable and resource efficient deployment of the selected value chains. Also, it suggests policy interventions that will overcome challenges, resolve gaps and as a result mobilize local biomass and improve market uptake. Finally, it discusses the contrasting paradigms for biomass policy formation within single sector target setting and the value chain approach of the Biomass Policy Framework and uses the case of low carbon biomass heat to illustrate the strengths of the suggested approach. The paper concludes with r

Panoutsou C, Chiaramonti D, 2020, Socio-economic opportunities from Miscanthus cultivation in marginal land for bioenergy, Energies, Vol: 13, ISSN: 1996-1073

Substantial areas of agricultural land in south European countries are becoming increasingly marginal and being abandoned due to arid climate with prolonged summers and low rainfall. Perennial, lignocellulosic crops, such as Miscanthus, offer an outlet that couples agriculture with energy, creates employment, and increases profits from feedstock production in rural areas. This research paper follows an Input Output methodology and uses an econometric model to investigate the impact of crop yielding performance and marginal land to jobs and profit from the cultivation and supply of Miscanthus in low quality, marginal land in Italy and Greece. Two value chain cases are analysed: small scale Combined Heat and Power (CHP) and Fast Pyrolysis Bio Oil (FPBO). The cultivation of Miscanthus in both reference value chains exhibits good employment prospects, with smaller scale value chains creating more labour-intensive logistics operations. The activities can also generate substantial financial profit especially with higher crop yields. Results show a pronounced relationship between profitability and crop yield for both reference value chains - cultivation and supply operations become more profitable with increasing yield. It is, therefore, important to achieve higher yields through good cropping practices, while maintaining high levels of environmental sustainability.

Panoutsou C, Singh A, Christensen T, 2020, Competitive priorities to address optimisation in biomass value chains: the case of biomass CHP, Managing Global Transitions: International Research Journal, Vol: 2, Pages: 60-75, ISSN: 2589-7918

Policy and industry decision makers place high priority on the contribution of biomass to the emerging low carbon, circular economy. Optimisation of performance, from the perspectives of environmental, social and economic sustainability and resource efficiency, is essential to successful development and operation of biomass value chains. The complexity of value chains, which comprise interrelated stages from land use to conversion and multiple end products, presents challenges.To date, decision makers have approached from the viewpoints of single market sectors or issues, such as market shares of bioeconomy and reduction of carbon emissions to mitigate climate change. This approach does not achieve a full understanding of value chains and their competitive priorities, limits consumer awareness, and poses risks of sub-optimal performance and under-development of potential local capacity.This paper presents a conceptual framework that combines value chain analysis and competitive priority theory with indicators suitable to measure, monitor and interpret sustainability and resource efficiency at value chain level. The case of biomass Combined Heat and Power (CHP) is used to illustrate how optimisation strategies can be focused to address challenges in value chain stages which will lead to better performance and uptake of sustainably sourced, widely accepted biomass options.

Panoutsou C, Alexopoulou E, 2020, Costs and profitability of crops for bioeconomy in the EU, Energies MDPI, Vol: 13, Pages: 1-27, ISSN: 1996-1073

The bioeconomy is the cornerstone of the EU’s policy for shifting economic and societal trends towards circularity and low carbon arrangements. Europe has several crops that can be used as raw materials for this purpose, however pressure on land which might displace other activities and industrial competition for cost efficient raw materials remains a challenge. Hence, ensuring good yielding capacity and examining the likelihood to produce more by exploiting low quality, unused land can present significant opportunities to increase sustainable, locally sourced supply and at the same time offer profitable solutions to both industry and the farmers. This paper estimates the production costs of fourteen crops (oil, sugar, starch and lignocellulosic) and analyses how their profitability can be influenced by yield increases and cultivation in low quality land. Results show that there are profitable options for all crops under current market prices and land types except for cases in countries where crop productivity is rather low to sustain farm incomes. The analysis confirms that Europe has plenty crop options as raw materials for bioeconomy. Decision makers however must ensure future research and policy support are oriented towards sustainable yield increases and accelerate rehabilitation of land that is unused and of low quality.

Chiaramonti D, Panoutsou C, 2019, Policy measures for sustainable sunflower cropping in EU-MED marginal lands amended by biochar: case study in Tuscany, Italy, Biomass and Bioenergy, Vol: 126, Pages: 199-210, ISSN: 0961-9534

The aim of this study is to evaluate economic support measures based on current EU policies affecting the profitability of large-scale deployment of biochar for sunflower cultivation in dry marginal lands in Italy, paving the way to large scale carbon sequestration in the EU Mediterranean region. Two cases were considered: i) straight biochar use and ii) biochar in combination with compost (COMBI: 20% biochar and 80% compost mass fraction), at application rates of 5 and 10 Mg ha−1 respectively. Based on realistic estimations of achievable crop-yield performances by biochar and COMBI addition to dry soils, the effect of current policies on the economic viability of biochar deployment and farmers’ income has been investigated. Using a cost-model we identified the required levels of support, in the form of (i) area subsidies for crop cultivation, (ii) tradable carbon certificates (credits), and (iii) REDII-compliant biofuel support for Aviation and Maritime, so to make biochar and sunflower cultivation in EU MED dry marginal lands competitive for sustainable crop-based biofuels. Results show that, by employing existing policy instruments, sufficient income can be generated for famers to recover marginal land, sequester large amount of carbon by BECCS at costs (∼82 € Mg−1 of CO2) falling at or below the typical range of CCS measures, as well as offer additional environmental and socio-economic positive benefits. The combination of currently operational economic mechanisms from the Common Agricultural Policy, the Climate Policy, and the Renewable Energy Directive II can: i) maintain domestic farming activities, ii) support the implementation of biochar projects at local level, iii) contribute to achieve EU and national biofuel targets without generating ILUC impacts and iv) achieve unprecedent potential for carbon sequestration. However, prior to large-scale deployment, targeted on-site R&D actions aimed at validating biochar effects under

Modelling and Optimisation of Biomass Supply Chains provides scientific evidence for assessing biomass supply and logistics, placing emphasis on the methods, modelling capacities and large data collection, processing, storage and update. The information presented builds on recent relevant research work from the Biomass Futures, Biomass Policies and S2Biom projects. In addition to technical issues, it covers economic, social, and environmental aspects with direct implications on biomass availability.Its chapters offer an overview of methodologies for assessing and modelling supply, biomass quality and requirements for different conversion processes, logistics and demand for biobased sectors. Case studies from the projects that inspire the book present practical examples of the implementation of these methodologies. The authors also compare methodologies for different regions, like Europe and the US. Biomass feedstock-specific chapters address the relevant elements for forest, agriculture, biowastes, post-consumer wood and non-food crops. Engineers in the bioenergy sector, as well as researchers and graduate students will find in this book a very useful resource when working on optimization and modelling of biomass supply chains. For energy policy makers, analysts and consultants, the book provides consistent and technically sound projections for policy and market development decisions.

Panoutsou C, 2016, The role of sustainable biomass in the heat market sector for EU27, Wiley Interdisciplinary Reviews Energy and Environment, Vol: 5, Pages: 430-450, ISSN: 2041-8396

This paper provides evidence-based information for biomass heat as a low-carbon option to meet the renewable energy targets in the European Union by employing both qualitative and quantitative frameworks in order to (1) characterize market segments within the heat, district heating, and combined heat and power (CHP) sectors in EU27; (2) define a set of key factors affecting future penetration of biomass in them; (3) evaluate the market segments across all the key factors and define which are the most promising for biomass uptake by 2020; and (4) assess the quantitative role that biomass can play in the various market segments for 2020. The demand analysis is combined with detailed cost supply information for a range of scenarios, from individual National Renewable Energy Action Plans (NREAPs) country information to explicit, consistent, and harmonized datasets for all EU Member States which also comply with two sets of sustainability criteria, one reflecting the Renewable Energy Directive (RED) and the other applying very strict mitigation factors to the biomass value chains and also expanding the RED criteria to all bioenergy carriers (liquid, solid, and gaseous).

The paper provides a high level scene setting analysis to understand the policy and legislative framework in which the diffusion of bioenergy takes place in Greece and local level analysis of the perceptions of the key stakeholders within the local community of Rodopi, in the northern part of the country. It is divided into six sections. Firstly the framework conditions for biomass heat and electricity generation in Greece are presented. In the second section the policy context is set in order to identify the key support mechanisms for bioenergy in the country. The third section presents an outline of the diffusion of bioenergy in terms of key groups involved as well as key factors affecting the planning and implementation of a bioenergy scheme at local/ regional and national levels. The fourth section reviews the perception of key stakeholders towards bioenergy/biofuels schemes at national level based on national networks. The fifth section focuses on a case study region (Rodopi, northern Greece) and provides an in- depth analysis for the perception of the main local actors (farmers and end users) based on structured questionnaire interviews. The final section provides the main conclusions from the surveys and draws a set of recommendations for the integration of bioenergy schemes into the Greek energy system.

Switchgrass has been proposed as a perennial plant suitable for biofuel production. Cultivar selection has a major impact on the ultimate productivity, persistence and profitability of the crop. The purpose of this work was to evaluate 16 switchgrass varieties (upland and lowland ones) for 5 years in Greece and Italy. One single winter harvest was carried out every year when the moisture content was less than 20% and biomass yields were determined. At the end of each growing season, the stem height and the number of tillers per square meter were measured. It was found that all varieties performed high yields in both sites except for the varieties 9005439 (upland) and 9005438 (lowland), which produced only 5.6 and 6.9 t ha−1, respectively. All varieties produced their best yields in the third growing season, 17.9 t ha−1 in Greece and 12.3 t ha−1 in Italy. Significantly higher mean yields were recorded in the Greek trial, apart from the lowland variety SL 93-3 that produced 20.8 t ha−1 in Italy and 18.1 t ha−1 in Greece. The lowland varieties (Cathage, Kanlow, SL 93-2 and SL 93-3) were found to be more productive compared to the upland varieties, averaged over the sites and the years. The best performing variety on every site (mean 1999–2002) was a lowland variety, Kanlow (17.1 t ha−1) in Greece and SL 93-3 (20 t ha−1) in Italy.

How large is the potential demand for bio-heat in the UK? Whilst most research has focused on the supply of biomass for energy production, an understanding of the potential demand is crucial to the uptake of heat from bioenergy. We have designed a systematic framework utilising market segmentation techniques to assess the potential demand for biomass heat in the UK. First, the heat market is divided into relevant segments, characterised in terms of their final energy consumption, technological and fuel supply options. Second, the key technical, economic and organisational factors that affect the uptake of bioenergy in each heat segment are identified, classified and then analysed to reveal which could be strong barriers, which could be surmounted easily, and for which bioenergy heat represents an improvement compared to alternatives. The defined framework is applied to the UK residential sector. We identify provisionally the most promising market segments for bioenergy heat, and their current levels of energy demand. We find that, depending on the assumptions, the present potential demand for bio-heat in the UK residential sector ranges between 3% (conservative estimate) and 31% (optimistic estimate) of the total energy consumed in the heat market.
