Abstract. With the increasing challenge to shift our economic system from carbon to renewable energy carriers the demand for biogenic resources is growing. Biogenic municipal waste, agricultural by-products and industrial residues are under-utilised but are increasingly gaining in value. To date, there is no continuous database for these resources in the EU-27 countries. Existing datasets that estimate resource potentials in a single time step often lack validation. A reliable and continuous database is thus needed to support the growing bioeconomy. Spatial and temporal high-resolution data of biogenic residues serve as an invaluable resource for identifying areas with significant theoretical biomass potential and allows an in-depth understanding of dynamic patterns over time. This study elucidates the theoretical biomass potentials of 13 distinct biomasses from municipal waste, agricultural by-products and industrial residues quantified annually from 2010–2020. The spatial scope of the research covers the EU-27 Member States incorporating all entities represented at various levels within the Nomenclature of Territorial Units for Statistics (NUTS) as delineated by Eurostat, where possible. The regionalised data are subsequently validated against national statistics. The findings demonstrate the feasibility of creating a time series of theoretical biomass potentials for the 13 selected waste types, by-products, and residues, and underscore the critical role of data validation when regionalising national or sub-national data to smaller NUTS entities. It could be shown that the values of small regions (NUTS 3) correlated well on average. When looking at individual regions in detail, regional characteristics such as the location of cultivation, waste management or reporting methods could lead to over- or underestimates of up to 100 %. Therefore, data at the regional level provide only limited information. In the case of industrial residues regionalisation gave good results localising preference regions of high theoretical biomass potential but more data on industrial production are needed to estimate also residual quantities at subnational and local levels. Biomass potentials modelled in this study are published in an open access database, which is designed as an extensible tool, enabling the understanding of national and regional trends of theoretical biomass potentials in the European Union and of the reliability of the regionalised data.

整个欧盟的理论生物量潜力的时间和空间映射

摘要。随着将我们的经济系统从碳转移到可再生能源载体的挑战越来越大，对生物资源的需求也在增长。生物来源的城市垃圾、农业副产品和工业残留物未得到充分利用，但价值越来越高。迄今为止，欧盟 27 国还没有这些资源的连续数据库。在单个时间步内估计资源潜力的现有数据集通常缺乏验证。因此，需要一个可靠且连续的数据库来支持不断增长的生物经济。生物残留物的时空高分辨率数据是识别具有显着理论生物量潜力的区域的宝贵资源，并且可以深入了解随时间变化的动态模式。本研究阐明了从 2010 年到 2020 年每年量化的来自城市垃圾、农业副产品和工业残留物的 13 种不同生物质的理论生物质潜力。研究的空间范围涵盖了欧盟 27 个成员国，并在可能的情况下将所有实体纳入欧盟统计局划定的统计领土单位命名法 (NUTS) 中的各个级别。随后根据国家统计数据验证区域化数据。研究结果证明了为 13 种选定的废物类型、副产品和残留物创建理论生物质潜力的时间序列的可行性，并强调了在将国家或地方数据区域化到较小的 NUTS 实体时数据验证的关键作用。可以看出，小区域（NUTS 3）的值平均相关性很好。在详细考察各个地区时，种植地点、废物管理或报告方法等地区特征可能导致高达 100% 的高估或低估。因此，区域层面的数据只能提供有限的信息。在工业残留物的情况下，区域化在定位具有高理论生物量潜力的偏好区域方面取得了良好的效果，但还需要更多关于工业生产的数据来估计国家以下和地方层面的残留量。本研究中模拟的生物质潜力发布在一个开放存取数据库中，该数据库被设计为一个可扩展的工具，有助于了解欧盟理论生物量潜力的国家和区域趋势以及区域化数据的可靠性。估计的理论潜力数据集可从以下网址免费下载：https://doi.org/10.48480/g53t-ks72（Günther 等人，2023 年）。
