Abstract: The increase in agricultural production and food quality has forced the growing useof plastics in various activities. 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 fortheir valorization at a regional level and from a circular economy perspective. In the scope of the Placarv õ es 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 wereproduced from plastic used on food packaging (PB-Samples) and sheeting film (PS-Samples) byactivation with K 2 CO 3 . ACs presented well-developed textural properties (PB-K 2 CO 3 -1:1–700 andPS-K 2 CO 3 -1:1–700 exhibited a volume of 0.32 and 0.25 cm 3 g − 1 and an apparent surface area of 723 and 623 m 2 g − 1 , 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.
