In the context of climate change and the circular economy, biochar has recently found many applications in various sectors as a versatile and recycled material. Here, we review application of biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, and energy storage. The ultimate storage reservoirs for biochar are soils, civil infrastructure, and landfills. Biochar-based fertilisers, which combine traditional fertilisers with biochar as a nutrient carrier, are promising in agronomy. The use of biochar as a feed additive for animals shows benefits in terms of animal growth, gut microbiota, reduced enteric methane production, egg yield, and endo-toxicant mitigation. Biochar enhances anaerobic digestion operations, primarily for biogas generation and upgrading, performance and sustainability, and the mitigation of inhibitory impurities. In composts, biochar controls the release of greenhouse gases and enhances microbial activity. Co-composted biochar improves soil properties and enhances crop productivity. Pristine and engineered biochar can also be employed for water and soil remediation to remove pollutants. In construction, biochar can be added to cement or asphalt, thus conferring structural and functional advantages. Incorporating biochar in biocomposites improves insulation, electromagnetic radiation protection and moisture control. Finally, synthesising biochar-based materials for energy storage applications requires additional functionalisation.

用于农学、畜牧业、厌氧消化、堆肥、水处理、土壤修复、建筑、能源储存和碳封存的生物炭:综述

在气候变化和循环经济的背景下,生物炭最近在各个领域发现了许多应用,作为一种多功能和可回收材料。在这里,我们回顾了基于生物炭的碳汇应用,涵盖农学、畜牧业、厌氧消化、堆肥、环境修复、建筑和储能。生物炭的最终储存库是土壤、民用基础设施和垃圾填埋场。以生物炭为基础的肥料,将传统肥料与生物炭作为营养载体相结合,在农学上很有前景。使用生物炭作为动物饲料添加剂在动物生长、肠道微生物群、减少肠道甲烷产生、产蛋量和减少内毒素方面显示出益处。Biochar 增强厌氧消化操作,主要用于沼气的产生和升级,性能和可持续性,以及抑制性杂质的减少。在堆肥中,生物炭控制温室气体的释放并增强微生物活性。共同堆肥 biochar 改善土壤性质并提高作物生产力。原始和工程生物炭也可用于水和土壤修复以去除污染物。在建筑中,生物炭可以添加到水泥或沥青中,从而赋予结构和功能优势。在生物复合材料中加入生物炭可改善绝缘、电磁辐射防护和湿度控制。最后,为储能应用合成基于生物炭的材料需要额外的功能化。biochar 控制温室气体的释放并增强微生物活性。共同堆肥 biochar 改善土壤性质并提高作物生产力。原始和工程生物炭也可用于水和土壤修复以去除污染物。在建筑中,生物炭可以添加到水泥或沥青中,从而赋予结构和功能优势。在生物复合材料中加入生物炭可改善绝缘、电磁辐射防护和湿度控制。最后,为储能应用合成基于生物炭的材料需要额外的功能化。biochar 控制温室气体的释放并增强微生物活性。共同堆肥 biochar 改善土壤性质并提高作物生产力。原始和工程生物炭也可用于水和土壤修复以去除污染物。在建筑中,生物炭可以添加到水泥或沥青中,从而赋予结构和功能优势。在生物复合材料中加入生物炭可改善绝缘、电磁辐射防护和湿度控制。最后,为储能应用合成基于生物炭的材料需要额外的功能化。生物炭可以添加到水泥或沥青中,从而赋予结构和功能优势。在生物复合材料中加入生物炭可改善绝缘、电磁辐射防护和湿度控制。最后,为储能应用合成基于生物炭的材料需要额外的功能化。生物炭可以添加到水泥或沥青中,从而赋予结构和功能优势。在生物复合材料中加入生物炭可改善绝缘、电磁辐射防护和湿度控制。最后,为储能应用合成基于生物炭的材料需要额外的功能化。
