In recent decades, ecosystems have suffered diverse environmental impacts caused by anthropogenic activities, including the dumping of plastic waste. This situation has prompted the European Union to introduce a new policy based on the circular economy. In this study, the present state and future perspectives on the generation and treatment of plastic waste in the intensive agriculture of Almeria (Spain) are analyzed. This activity generates 1503.6 kg·ha·year, on average, of plastic waste with an approximate treatment cost of 0.25 €/kg. The present study shows that the volume of plastic waste from intensive agriculture in Almeria is constantly increasing (48,948.2 tons in 2020/21) and it is suggested that the current management system does not meet the needs of the sector. Although it presents great opportunities for improvement under the framework of the circular economy. Furthermore, this work reports a direct relationship between the price of the raw materials needed for the production of plastic and the volume of recycled plastics. For this reason, it would be advisable for the administration to consider the implementation of a tax rebate system for the sector and specifically when the petroleum derivatives used to manufacture plastic are less expensive, and the recycling option is not so attractive.
近几十年来，由于人为活动造成的各种环境影响，包括塑料废物的倾倒，生态系统受到了损害。这种情况促使欧盟出台了一项基于循环经济的新政策。本研究分析了西班牙阿尔梅里亚集约农业中塑料废物的产生和处理现状和未来展望。该活动平均每年产生 1503.6 公斤/公顷的塑料废物，其处理费用约为 0.25 欧元/公斤。本研究表明，阿尔梅里亚集约农业的塑料废物量在不断增加（2020/21 年为 48948.2 吨），并且建议现行管理制度无法满足该行业的需求。尽管在循环经济框架下有很大的改进空间。此外，这项工作还报告了用于生产塑料的原材料价格与回收塑料量之间的直接关系。因此，管理部门考虑为该行业实施退税制度是明智的，特别是当用于制造塑料的石油衍生品价格较低且回收选择不那么有吸引力时。
