Abstract

In most current academic thinking, the prevailing consensus underscores the potential of algae as a promising biochar feedstock. Nevertheless, a significant gap exists in the literature, as most assertions conducted outside tropical and subtropical regions lack substantiation through comprehensive analyses on a comparison of the economic benefits and the costs associated with the application of algae biochar is mostly missing. This study reports a meticulous breakdown of production costs for algae biochar derived from 6 various cultivation systems via 2 harvesting techniques under the conditions characteristic of central Europe. The findings revealed that the production costs of the algae biochars always greater than 110 €.kg−1that is much higher than the selling prices of the most common biochars on the market including the most expensive biochars made of hard woods. To achieve social acceptability, it is recommended to prefer higher value-added applications for algae and to implement biochar production as the final stage of the refining process.

成本明细显示,在中欧利用微藻生产生物炭需要创新的培养程序
在当前大多数学术思想中,普遍共识强调藻类作为一种有前途的生物炭原料的潜力。然而,文献中还存在着巨大的空白,因为热带和亚热带地区以外的大多数论断都缺乏对应用藻类生物炭的经济效益和相关成本进行比较的全面分析。本研究报告详细分析了在中欧特有的条件下,通过 2 种收获技术从 6 种不同的栽培系统中提取的海藻生物炭的生产成本。研究结果表明,海藻生物炭的生产成本始终高于 110 欧元/千克-1,远远高于市场上最常见的生物炭(包括最昂贵的硬木生物炭)的销售价格。为实现社会可接受性,建议优先考虑海藻的高附加值应用,并将生物炭生产作为精炼过程的最后阶段。
