摘要

咖啡是世界上最受欢迎的饮料之一。超过50%的咖啡渣在使用后被丢弃，成为一个重要的废物来源，被称为废咖啡渣(SCG)。利用SCG作为生产沼气的原料具有巨大的潜力。在这项研究中，我们研究了SCG的生化组成及其作为绿色能源的潜力。我们证明，SCG可以产生0.1559 Nm3 CH4 / kg COD，而从底物中提取多酚可以使这一产量提高近100%。相比之下，使用HCl的酸处理对这种生物质的产气没有影响。

Can coffee grounds be considered as a potential for green energy production?

Coffee is one of the most popular beverages in the world. Over 50% of this mass is discarded after use, becoming a significant waste source known as spent coffee grounds (SCG). SCG usage as a raw material for biogas production emerges with great potential. In this study, we investigated the biochemical composition of SCG and its potential as a green energy source. We demonstrated that SCG can produce 0.1559 Nm3 CH4 / kg COD and that the extraction of polyphenols from the substrates can increase this production by almost 100%. In contrast, acid treatment using HCl showed no effect on gas production from this biomass.
