Abstract

In this work, a brief assessment of using microalgae (Arthrospira platensis PCC 8005) for lowering carbon emissions during biotrickling filtration of volatile organic compounds (VOCs) from air is performed. In this regard, the removal efficiency of acetic acid vapors (used as model VOC in this study) and carbon dioxide production from this process are evaluated in the presence of: (1) classical microorganisms (e.g. from compost), (2) mixture of compost microorganisms and microalgae, (3) microalgae. A blank trial (microorganisms-free) was considered as reference. The obtained results indicate the contribution of both microorganism-s type (alone or in mixture) to the VOC removal. Remarkably, their mixture exhibited the lowest carbon emission and thus the highest environmental performance due not only VOC biodegradation, but also simultaneously carbon dioxide uptake by microalgae.
