“…However, when epigeous plant parts were removed, the reduction increased. From this observation, it could be concluded that a large part of the reduction of VOCs can be allotted to an increased diffusion in the soil microcosm and not to adsorption on the plant surface. A follow-up study demonstrated changes in the soil microcosm due to the exposure of gasoline VOCs .…”

Common ivy (CI) or Hedera Helix L., is a clinging evergreen vine that can be cultivated on any vertical surface (walls, fences, tree trunks, etc.). In Europe, CI has been recommended by governments to plant in urban areas because it lowers urban heat island effects and improves urban air quality. Regular trimmings of these vertical greenery systems would be necessary, which would yield a potentially interesting novel biomass resource for urban biorefinery concepts. Furthermore, CI extracts contain pharmaceutically active compounds (e.g., hederacoside C and α-hederin), which constitute the active components of commercially available cough syrups. Moreover, research on their suitability to treat (lung) inflammations and suppress cancer tumor growth is ongoing and shows promise. CI extracts also have demonstrated potential for their application in the agricultural industry to serve as antifungal agents. Recently, postextracted residues of CI have shown to be a promising feedstock for green fertilizer production via slow pyrolysis. Moreover, a provisional sustainability assessment indicated that the proposed process would be both carbon-and energy-negative. Therefore, a novel circular biorefinery approach is proposed, which entails the lifecycle of CI, from cultivation in vertical ecosystems via refinery into bioproduct(s) and valuable nutrients, and then back into soil.

“…The root zone's capacity for VOC removal is largely determined by the structure of its microbial populations (90%); however, only a very small fraction (10%) of VOC removal can be attributed to adsorption by the growing medium. The soil microflora plays a considerable role in the removal of gasoline VOCs (Cruz et al 2019). This microbe-assisted VOC removal is indirectly assisted by plants by nourishing the root zone-associated microbial population (Wood et al, 2002b;Kang and Freeman 2007;Torphy et al 2013;Kim et al 2021).…”

“…The role of green plants in improving indoor air pollution has been well established (Wood et al 2006;Weyens et al 2015;Han et al 2020;Liu et al 2022). Various species of ornamental plants have been found efficient in pollutant elimination for indoor air (Yang et al 2009;Cruz et al 2019;Wang et al, 2020b). The type and selection of plants also have a great influence on the VOC removal rate (Kim and Paulos, 2010).…”

“…A NASA (National Aeronautics and Space Administration) study in space shuttles in 1980 successfully demonstrated the role of plants in airborne pollutants removal (Wolverton et al 1989;Chen et al 2005). Several other recent investigations revealed that long-term exposure of pollutants to plants under both indoor and control chamber experiments led to the removal of maximum percent of pollutants from the indoor air (Cruz et al 2014).…”

“…Various studies have shown that indoor potted plants have the potential to reduce VOCs concentrations in the indoor environment(Wolverton et al 1989;Orwell et al 2006;Irga et al 2013;Cruz et al 2019;Moya et al 2021).VOCs removal by plants is not solely dependent on the aerial parts of plants; other factors, such as the quality and quantity of microflora in the soil, the microflora associated with the roots of the potted plant, and the type of plant-growing medium, all play role in VOCs removal. The present review focuses on the role of plants in VOC removal by different pathways.…”

Environmental pollution, especially indoor air pollution, has become a global issue and affects nearly all domains of life. Being both natural and anthropogenic substances, indoor air pollutants lead to the deterioration of the ecosystem and have a negative impact on human health. Cost-effective plant-based approaches can help to improve indoor air quality (IAQ), regulate temperature, and protect humans from potential health risks. Thus, in this review, we have highlighted the common indoor air pollutants and their mitigation through plant-based approaches. Potted plants, green walls, and their combination with bio-filtration are such emerging approaches that can efficiently purify the indoor air. Moreover, we have discussed the pathways or mechanisms of phytoremediation, which involve the aerial parts of the plants (phyllosphere), growth media, and roots along with their associated microorganisms (rhizosphere). In conclusion, plants and their associated microbial communities can be key solutions for reducing indoor air pollution. However, there is a dire need to explore advanced omics technologies to get in-depth knowledge of the molecular mechanisms associated with plant-based reduction of indoor air pollutants.
