This paper addresses the challenges of the transition from a fossil fuel-dependent to a bio-based economy and implications related to the production of food, feed, bioenergy and other bio-based materials. The objective is to provide a comprehensive review of global biomass and biomass-based energy supplies and demand, with particular attention to the EU. Furthermore, factors related to setting priorities in the use of non-food biomass are discussed, as food security will remain the top priority. Finally, the changes in the bioenergy balance indicators in the Member States of the EU and new plant breeding technologies are analyzed. Overall, this study describes the complexity of the bio-based value chains in making decisions on how best to use biomass. The article presents a comprehensive review on global biomass and biomass based energy supplies and demand, discusses the European chemical industry perspective, analyzes the changes in the biomass based energy balance indicators in the Member States of the EU, and considers the challenges of the new plant breeding technologies.

生物经济：生物质和基于生物质的能源供需

本文讨论了从依赖化石燃料向生物基经济转变的挑战，以及与食品、饲料、生物能源和其他生物基材料生产相关的影响。目标是全面审查全球生物质和基于生物质的能源供应和需求，特别关注欧盟。此外，还讨论了与确定非食用生物质使用优先顺序相关的因素，因为粮食安全仍将是重中之重。最后，分析了欧盟成员国生物能源平衡指标的变化和新的植物育种技术。总的来说，这项研究描述了生物价值链在决定如何最好地利用生物质时的复杂性。
