Constructed wetland: multi-functional benefits of an ecological engineered system
Ojediran, Adetunji; Pereira, Sofia Almeida; Rosa-Santos, Paulo; Rodrigues, Ana Cristina; Calheiros, CristinaIntroduction: Constructed wetlands (CWs) are engineered systems that are inspired by natural wetlands [1]. They are often applied for decentralized wastewater treatment, but while their performance in pollutant removal is well established, other potential ecosystem services are often underappreciated. This study aims to bring attention to the broader multifunctional benefits of CWs —beyond treatment —by explori...
Microbial fuel cells’ integration in constructed wetlands: a mini-review
Ojediran, Adetunji A.; Pereira, Sofia I. A.; Rosa-Santos, Paulo; Rodrigues, Ana C.; Calheiros, Cristina S. C.Background & Aims: Constructed wetlands (CW) are widely recognized as an e?ective nature-based solution for wastewater treatment with benefits that include low energy consumption, ecological enhancement, aesthetics, and carbon sequestration potential (Calheiros et al., 2015; Vymazal, 2011). As stated by Justino et al. (2023) and Vymazal (2011) CW’s performance could be enhanced through hybrid configurations, co...
Advanced treatment in constructed wetlands: the role of photocatalytic modules ...
Ojediran, Adetunji A.; Pereira, Sofia I. A.; Rosa-Santos, Paulo; Arenas, Francisco; Dolbeth, Marina; Ntougias, Spyros; Calheiros, Cristina S. C.Background & Aim: Constructed wetlands (CWs) have emerged as a leading nature-based solution (NBS) for wastewater treatment, offering multiple benefits such as low maintenance costs, high pollutant removal efficiency, carbon sequestration, biodiversity enhancement, and aesthetic value (Justino et al., 2023; Kadlec, 2008). However, in tourism facilities, two major challenges affect wastewater management: seasona...
Soluções baseadas na natureza para a resiliência do território
Calheiros, Cristina S. C.; Ojediran, Adetunji; Mesquita, Ana; Costa, Isabella; Magalhães, João; Carrillo, Valentina; Antão-Geraldes, Ana M.Introdução: As Soluções Baseadas na Natureza (SbN) têm vindo a destacar-se como abordagens eficazes para responder aos desafios societais da atualidade, promovendo territórios mais sustentáveis, circulares e resilientes. Quando integradas em infraestruturas verdes, redes de áreas naturais e seminaturais, contribuem significativamente para a conservação da biodiversidade, o sequestro de carbono, a gestão sustent...
Infraestruturas verdes e prestação de serviços ecossistémicos
Calheiros, Cristina S. C.; Ojediran, Adetunji; Mesquita, Ana; Costa, Isabella; Magalhães, João; Carrillo, Valentina; Antão-Geraldes, Ana M.Enquadramento: As infraestruturas verdes correspondem a uma rede de áreas naturais e seminaturais que oferecem múltiplos benefícios, tais como a conservação da natureza, o sequestro de carbono, a gestão sustentável da água e a melhoria da qualidade de vida, entre outros serviços ecossistémicos. Estas infraestruturas verdes podem integrar soluções baseadas na natureza (SbN), contribuindo para a sustentabilidade ...
Microbial fuel cells’ integration in constructed wetlands: a mini-review
Ojediran, Adetunji; Pereira, Sofia; Rosa-Santos, Paulo; Rodrigues, Ana; Calheiros, Cristina S. C.Introduction: Constructed wetlands (CWs) are sustainable wastewater treatment systems leveraging natural processes to remove pollutants. Microbial fuel cells (MFCs) enhance CWs by converting organic matter into bioelectricity via electroactive bacteria [1]. Integrating MFCs with CWs creates hybrid systems that improve treatment efficiency and generate renewable energy. The CW-MFC’s performance factors include d...
Constructed wetland: multi-functional benefits of an ecological engineered system
Ojediran, Adetunji; Pereira, Sofia; Rosa-Santos, Paulo; Rodrigues, Ana; Calheiros, Cristina S. C.Introduction and aim: Constructed wetlands (CWs) are engineered systems inspired by natural wetlands and commonly used for decentralized wastewater treatment. Although their efficiency in pollutant removal is well recognized, other ecosystem services they provide are often overlooked. This work highlights these broader multifunctional benefits through a real-scale horizontal subsurface flow CW (HSSF-CW) operati...
Carbon sequestration potential in constructed weatlands: a mini-review
Ojediran, Adetunji; Pereira, Sofia; Rosa-Santos, Paulo; Calheiros, Cristina S. C.Background: Wetlands are “high-carbon ecosystems,” covering only 5–8% of the Earth’s land surface yet storing 20–30% of terrestrial carbon. Constructed wetlands (CWs), originally designed for wastewater treatment, also provide carbon sequestration alongside biodiversity support, flood regulation, and landscape enhancement. Studies show high carbon sequestration rates (CSR) during the first 0–15?years of CWs, fo...
