The plastic wastes are partially recycled in or outside Portugal; nevertheless, the contaminated wastes are sent to landfill. It is crucial to consider new models for their valorization at a regional level and from a circular economy perspective. In the scope of the Placarv\u00f5es project, a study was elaborated, which included the types and quantities of plastics used in the irrigation area of the Alqueva Dam, in southern Portugal. The crops that use the most plastic are intensive olive groves, almonds, and table grapes, which represent more than 91% of total plastic waste. The production of activated carbons (ACs) is a solution to avoid plastics landfill. ACs were produced from plastic used on food packaging (PB-Samples) and sheeting film (PS-Samples) by activation with K2CO3. ACs presented well-developed textural properties (PB-K2CO3-1:1\u2013700 and PS-K2CO3-1:1\u2013700 exhibited a volume of 0.32 and 0.25 cm3 g\u22121 and an apparent surface area of 723 and 623 m2 g\u22121, respectively). Both ACs performed very well concerning four pesticide removals from the liquid phase. This solution is very promising, such these ACs could be applied in effluent treatments on a large scale.<\/jats:p>","DOI":"10.3390\/agronomy12010134","type":"journal-article","created":{"date-parts":[[2022,1,6]],"date-time":"2022-01-06T03:41:32Z","timestamp":1641440492000},"page":"134","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Dealing with Plastic Waste from Agriculture Activity"],"prefix":"10.3390","volume":"12","author":[{"given":"Teresa","family":"Batista","sequence":"first","affiliation":[{"name":"Instituto Mediterr\u00e2neo para a Agricultura, Ambiente e Desenvolvimento (MED), Universidade de \u00c9vora, P\u00f3lo da Mitra, Apartado 94, 7006-554 \u00c9vora, Portugal"},{"name":"Comunidade Intermunicipal do Alentejo Central, Rua 24 de Julho, n\u00ba1, 7000-673 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2085-9157","authenticated-orcid":false,"given":"Isabel Pestana da Paix\u00e3o","family":"Cansado","sequence":"additional","affiliation":[{"name":"LAQV-Requimte, Instituto Mediterr\u00e2neo para a Agricultura, Ambiente e Desenvolvimento (MED), Institute for Research and Advanced Training (IIFA), Universidade de \u00c9vora, Rua Rom\u00e3o Ramalho, n\u00ba59, 7005-671 \u00c9vora, Portugal"},{"name":"Instituto Mediterr\u00e2neo para a Agricultura, Ambiente e Desenvolvimento (MED), Institute for Research and Advanced Training (IIFA), Universidade de \u00c9vora, Rua Rom\u00e3o Ramalho, n\u00ba59, 7005-671 \u00c9vora, Portugal"}]},{"given":"Barbara","family":"Tita","sequence":"additional","affiliation":[{"name":"Empresa de Desenvolvimento e Infraestruturas de Alqueva (EDIA, SA), Departamento de Ambiente e Ordenamento do Territ\u00f3rio, Rua Zeca Afonso, n\u00ba2, 7800-522 Beja, Portugal"}]},{"given":"Ana","family":"Ilh\u00e9u","sequence":"additional","affiliation":[{"name":"Empresa de Desenvolvimento e Infraestruturas de Alqueva (EDIA, SA), Departamento de Ambiente e Ordenamento do Territ\u00f3rio, Rua Zeca Afonso, n\u00ba2, 7800-522 Beja, Portugal"}]},{"given":"Luis","family":"Metrogos","sequence":"additional","affiliation":[{"name":"Comunidade Intermunicipal do Alentejo Central, Rua 24 de Julho, n\u00ba1, 7000-673 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3634-2390","authenticated-orcid":false,"given":"Paulo Alexandre Mira","family":"Mour\u00e3o","sequence":"additional","affiliation":[{"name":"Instituto Mediterr\u00e2neo para a Agricultura, Ambiente e Desenvolvimento (MED), Institute for Research and Advanced Training (IIFA), Universidade de \u00c9vora, Rua Rom\u00e3o Ramalho, n\u00ba59, 7005-671 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9572-6346","authenticated-orcid":false,"given":"Jo\u00e3o Manuel Valente","family":"Nabais","sequence":"additional","affiliation":[{"name":"Comprehensive Health Research Center (CHRC), Departamento de Ci\u00eancias M\u00e9dicas e da Sa\u00fade, Escola da Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, Rua Rom\u00e3o Ramalho, 59, 7000-671 Evora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2990-6394","authenticated-orcid":false,"given":"Jos\u00e9 Eduardo","family":"Castanheiro","sequence":"additional","affiliation":[{"name":"Instituto Mediterr\u00e2neo para a Agricultura, Ambiente e Desenvolvimento (MED), Institute for Research and Advanced Training (IIFA), Universidade de \u00c9vora, Rua Rom\u00e3o Ramalho, n\u00ba59, 7005-671 \u00c9vora, Portugal"}]},{"given":"C\u00e1tia","family":"Borges","sequence":"additional","affiliation":[{"name":"Gesamb\u2013Gest\u00e3o Ambiental e de Res\u00edduos, EIM, Estrada das Alc\u00e1\u00e7ovas, EN 380, 7000-175 \u00c9vora, Portugal"}]},{"given":"Gilda","family":"Matos","sequence":"additional","affiliation":[{"name":"Gesamb\u2013Gest\u00e3o Ambiental e de Res\u00edduos, EIM, Estrada das Alc\u00e1\u00e7ovas, EN 380, 7000-175 \u00c9vora, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,6]]},"reference":[{"key":"ref_1","unstructured":"(2021, August 29).
