Agricultural residues represent a valuable opportunity to develop circular bioeconomic systems centered on biomass. Characterizing this type of biomass can alleviate the pressure on current biomass sources (e.g., in forests and their biodiversity), enhance agricultural waste management, and reduce crop field emissions. Thus, this study aimed to evaluate the potential of agricultural plant-based residues as feedstock for thermochemical conversion processes, focusing on potato above-ground biomass to enhance herbaceous characterization. The gravimetric characterization of this type of biomass revealed a water content of 89 % for potato above-ground biomass with differences per plant section. Biomass abundance was also measured, showing that well-developed leaves and main stems were more plentiful. After 70 days after planting (DAP), maximum plant development was achieved, differing from heights development at 40 DAP. Hence, identifying specific times for residue recovery can help develop strategies for biomass recovery, thereby reducing pretreatment costs following the selection of suitable conversion technologies.

超越农业废弃物：基于马铃薯地上生物质的热化学转化原料表征


农业废弃物代表了发展以生物质为中心的循环生物经济系统的宝贵机会。表征这种类型的生物质可以减轻当前生物质来源（例如，森林及其生物多样性）的压力，加强农业废物管理，并减少农田排放。因此，本研究旨在评估农业植物残留物作为热化学转化过程原料的潜力，重点关注马铃薯地上生物质以增强草本特征。这种生物质的重量学表征显示，马铃薯地上生物质的含水量为 89%，每个植物部分的含水量不同。还测量了生物量丰度，表明发育良好的叶子和主茎更丰富。种植后 70 天 （DAP） 后，实现了最大的植物发育，与 40 DAP 的高度发育不同。因此，确定残留物回收的具体时间有助于制定生物质回收策略，从而在选择合适的转化技术后降低预处理成本。
