Constructed wetlands (CWs) constitute a promising sustainable solution for proper in situ domestic wastewater treatment. This literature review elucidates the status of CWs implementation in the hospitality industry to help foster the exchange of experiences in the field and deliver examples of approaches in different contexts to support future applications of this technology. Most of the studies reported in the literature were conducted in Europe, but studies emanating from Asia and South America are also available. The design of CWs, the horizontal and vertical subsurface flow CWs (HSFCW, VSFCW), and hybrid systems have been reported. The average removal efficiencies of the systems ranged from 83 to 95% for biochemical oxygen demand, 74 to 94% for chemical oxygen demand, 78 to 96% for total suspended solids, 75 to 85% for ammonium, 44 to 85% for ammonia, 50 to 73% for nitrate, 57 to 88% for total Kjeldahl nitrogen, 51 to 58% total nitrogen, and 66 to 99% for total phosphorus. The majority of the systems were implemented as decentralized treatment solutions using HSFCWs, with the second most common design being the hybrid CW systems in order to reduce area requirements, increase treatment efficiency, and prevent clogging. Overall, CWs are a promising sustainable solution which may support access to adequate sanitation worldwide as well as safe wastewater recycling and reuse, leading to more sustainable tourist destinations.<\/jats:p>","DOI":"10.3390\/hydrology10070153","type":"journal-article","created":{"date-parts":[[2023,7,20]],"date-time":"2023-07-20T04:27:13Z","timestamp":1689827233000},"page":"153","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Constructed Wetlands as Nature-Based Solutions for Wastewater Treatment in the Hospitality Industry: A Review"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4405-0184","authenticated-orcid":false,"given":"Sara","family":"Justino","sequence":"first","affiliation":[{"name":"Institute of Science and Environment (ISE), University of Saint Joseph, Macau SAR, China"},{"name":"Interdisciplinary Centre of Marine and Environmental Research (CIIMAR\/CIMAR), University of Porto, Novo Edif\u00edcio do Terminal de Cruzeiros do Porto de Leix\u00f5es, Avenida General Norton de Matos, S\/N, 4450-208 Matosinhos, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3159-3497","authenticated-orcid":false,"given":"Cristina","family":"Calheiros","sequence":"additional","affiliation":[{"name":"Institute of Science and Environment (ISE), University of Saint Joseph, Macau SAR, China"},{"name":"Interdisciplinary Centre of Marine and Environmental Research (CIIMAR\/CIMAR), University of Porto, Novo Edif\u00edcio do Terminal de Cruzeiros do Porto de Leix\u00f5es, Avenida General Norton de Matos, S\/N, 4450-208 Matosinhos, Portugal"}]},{"given":"Paula","family":"Castro","sequence":"additional","affiliation":[{"name":"CBQF\u2014Centro de Biotecnologia e Qu\u00edmica Fina\u2014Laborat\u00f3rio Associado, Universidade Cat\u00f3lica Portuguesa, Escola Superior de Biotecnologia, Rua Diogo Botelho 1327, 4169-005 Porto, Portugal"}]},{"given":"David","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Institute of Science and Environment (ISE), University of Saint Joseph, Macau SAR, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,20]]},"reference":[{"key":"ref_1","unstructured":"Pisano, U., Endl, A., Berger, G., and The Rio+20 Conference 2012: Objectives, Processes and Outcomes (2023, April 09).
