The efficient use of biogenic residues can make a significant contribution to increase resource efficiency. Due to its high energy efficiency, hydrothermal carbonization (HTC) is being discussed as a potentially suitable technology for particularly wet and sludgy biogenic residues. In Germany, however, it has not yet been established at industrial continuous operation. Among others, this is due to missing solutions for the economic treatment of the high organic loads in the liquid by-product and insufficient knowledge on long-term processing. Nevertheless, it is still expected that HTC could be able to contribute in the future, especially for sewage sludge disposal. Whether and under what conditions this could be the case is the subject of this study. The competitiveness of modeled cases for industrial sewage sludge HTC, which address different future paths, compared to thermal sludge treatment is investigated by using a multi-criteria instrument. Results show that HTC can only compete with the reference technology if certain framework conditions are given. Particularly, an efficient phosphorus recycling should be integrated and the production costs of the solid product should be at least less than €325 per metric ton according to this case study. The treatment performance of the liquid phase should be as high as possible whereby costs for further treatment equipment should be minimized, so that mentioned productions costs are not exceeded.

德国用于污泥处置的水热碳化：2030 年工业规模情景的比较评估

生物残留物的有效利用可以为提高资源效率做出重大贡献。由于其高能效，水热碳化 (HTC) 正在被讨论为一种潜在适用于特别潮湿和泥泞的生物残留物的技术。然而，在德国，它尚未建立在工业连续操作上。其中，这是由于缺少对液体副产品中的高有机负荷进行经济处理的解决方案，以及对长期加工的了解不足。尽管如此，HTC仍有望在未来做出贡献，尤其是在污水污泥处理方面。是否以及在什么条件下会出现这种情况是本研究的主题。工业污水污泥HTC示范案例的竞争力，与热污泥处理相比，这些解决了不同的未来路径，通过使用多标准仪器进行了研究。结果表明，HTC 只能在给定特定框架条件的情况下与参考技术竞争。特别是，根据本案例研究，应整合有效的磷回收，固体产品的生产成本应至少低于每公吨 325 欧元。液相的处理性能应尽可能高，从而应将进一步处理设备的成本降至最低，从而不超过上述生产成本。这篇文章满足了金-金的要求 结果表明，HTC 只能在给定特定框架条件的情况下与参考技术竞争。特别是，根据本案例研究，应整合有效的磷回收，固体产品的生产成本应至少低于每公吨 325 欧元。液相的处理性能应尽可能高，从而应将进一步处理设备的成本降至最低，从而不超过上述生产成本。这篇文章满足了金-金的要求 结果表明，HTC 只能在给定特定框架条件的情况下与参考技术竞争。特别是，根据本案例研究，应整合有效的磷回收，固体产品的生产成本应至少低于每公吨 325 欧元。液相的处理性能应尽可能高，从而应将进一步处理设备的成本降至最低，从而不超过上述生产成本。这篇文章满足了金-金的要求 液相的处理性能应尽可能高，从而应将进一步处理设备的成本降至最低，从而不超过上述生产成本。这篇文章满足了金-金的要求 液相的处理性能应尽可能高，从而应将进一步处理设备的成本降至最低，从而不超过上述生产成本。这篇文章满足了金-金的要求http://jie.click/badges 中描述的JIE数据开放徽章。
