Topic 4: Bioeconomy Sustainability, Impacts and Policies
(Please refer to https://www.eubce.com/conference-topics.html for a full list of sub-Topics within Topic 4)
Two visual/poster sessions start the week for Topic 4. The first is a joint session (4AV.1) for Topic 4.1, “Sustainability and Socio-economic Impacts”, Topic 4.4, “Biomass Strategies and Policies towards a Bioeconomy”, and Topic 4.5, “Resource Efficient Bioeconomy and Social Opportunities”, on the subject of “Biomass Strategies and Sustainability Implementation Towards a Bioeconomy” and starting at 14:00. This visual session covers different methodologies to assess sustainability, including certification, for different regions and pathways. The session also deals with strategies and policies for bioeconomy in many different countries and regions of the world, for example Thailand’s Path towards Sustainable Development, a guideline to create regional bioeconomy hubs in Germany, and includes a wide range of biomass substrates, and their conversion to diverse bioproducts, for example sugarcane for renewable electricity in Brazil. In addition, resource efficiency in value chains for energy, fuels and biobased products for the bioeconomy are addressed, for example grasses and rural agri-food value chains, vertical farming and BECCS, wood ash fertilisers and social dimensions of the bioeconomy.
Starting at 15:10 for Topic 4.2, “Environmental Impacts”, and for Topic 4.3, “Climate Impacts and GHG Performance” is session 4AV.2 on “Environmental and Climate Impacts of Biomass Systems”. This session deals with land and soil interactions associated with biomass production systems from an ecosystem perspective, and includes for example soil quality & GHG emissions from periodically wet soils for different cropping systems, emissions from residential wood burning, yield estimation and water use efficiency for sugarcane production, and life cycle assessment of algal biofuel cultivated in bioreactors. This session also deals with a range of processes for reducing GHG emissions, including the life cycle effects of sugarcane straw removal, carbon capture, retrofitting bioenergy plants with carbon dioxide capture equipment, C-efficiency in energy systems (including transport), a new index to track the performance of biofuel production, and the impacts of biomass crops on soils in different regions of the world.
There are two oral sessions for Topic 4.
Starting at 15:10, for Topic 4.4 “Biomass Strategies and Policies towards a Bioeconomy”, the oral session 4BO.12, “Strategy Guidance for Local and Regional Bioenergy Projects”, illustrates approaches as to how local and regional projects for non-food biomass projects for bioenergy and the wider bioeconomy can be fostered. Examples are given of non-food crops providing feedstocks for bio-based products and materials as part of the growing EU circular economy, and the prospect of reviving perennial energy crop cultivation to support energy decarbonisation in the UK.
The second oral session is for Topic 4.5, “Resource Efficient Bioeconomy and Social Opportunities”, starting at 16:20. Session 4BO.15 on “Resource Efficient Bioeconomy” addresses resource efficiency in industrial and policy related circular economy strategies. Included are examples of impacts of increased pellet production in SE USA, the role of the circular economy in climate change mitigation, and a European programme for climate, competitiveness and employment.
There are three oral sessions for Topic 4 on Wednesday. Starting at 09:00 for Topic 4.1, “Sustainability and Socio-economic Impacts”, is 4CO.4 entitled “Fostering Sustainability in Bioeconomy” and giving examples of applied sustainability in different supply chains and regions around the world, for example food security in global supply chains, food waste as valuable resource in the European waste management system, sustainability and safety assessment of DME production from biomass and landscape governance in a sustainable bioeconomy.
Commencing at 14:00 is the oral session for Topic 4.2, “Environmental Impacts”. Session 4CO.6 is entitled “Environmental Assessments of Biomass Systems” and evaluates the environmental impacts of different biomass, bioenergy and biorefinery systems, ranging from rice straw to grass and residues. Examples include, LCA for upgraded agricultural residues in a biorefinery setting, LCA for biogas from different feedstocks and dynamic sustainability analysis of green biorefineries.
The third oral session is for Topic 4.3, “Climate impacts and GHG performance” and starts at 15:10. Session 4CO.10 on “Environmental Impacts of Biomass Systems” covers different conversion routes and their contribution to climate mitigation. The approaches are diverse in relation to conversion technologies addressed, methodologies applied, and policy perspectives taken. Examples are given of the environmental impact of the EU using solid biomass for its 2030 renewable energy target, identification of barriers to the development of multi-output biorefineries imposed by implementation of the EU RED II and the impacts on soils of a shift from straw incorporation to the use of straw for biofuels as part of the debate on biofuels and climate change mitigation.
The day starts with the second oral session for Topic 4.3, “Climate impacts and GHG performance”, at 09:00. Session 4DO.2 on “GHG Performance of Bioenergy Including Carbon Capture” covers different strategies for climate mitigation, including BECCS, BECCUS and anaerobic digestion of wastewater.
Starting at 10:10 is the second of two oral sessions for Topic 4.4, “Biomass Strategies and Policies towards a Bioeconomy”. This session 4DO.5, entitled “International Strategies and Governance Systems for Bioenergy and the Bioeconomy”, addresses a variety of strategies and governance mechanisms to steer bioenergy and the bioeconomy in different regions of the world, including development of optimised biomass strategies in a bioeconomy through use of value chain indicators, governance in the transition to a circular and climate neutral society, and the potential of biofuels in international shipping decarbonization.
