The collection of Waste Cooking Oils (WCOs) has been growing in recent years due to the increase in society's awareness of environmental aspects since the uncontrolled disposal of WCOs has substantial adverse environmental impacts. WCOs are potential secondary raw materials for producing environmentally friendly biodiesel, which reduces pollution, promotes renewable energy use, and decreases waste. Nevertheless, the presence of several degradation products requires different pre-treatments before their conversion, significantly impacting the economic feasibility of the process. In addition, even pre-treated WCOs may have physical and chemical properties that do not guarantee the production of good-quality biodiesel. Therefore, it is essential to know the degradation reactions occurring during the oil frying and successive storage. Only WCOs that satisfy specific criteria would be used for high-quality biodiesel production. Then, a collection and storage method aimed at biodiesel production should be promoted. The current collection method does not provide for any special measures, storage containers, and temperatures. Instead, it is desirable to have proper collection and storage of WCOs to minimize degradation and have good WCOs before the conversion into biodiesel. Any business generating WCO should be provided with specialized, food grade, stainless steel, or plastic oil storage units that streamline the used cooking oil collection and are ready for scheduled collection. Managing household WCOs appears more complicated, but simple operations such as preliminary filtration and suitable containers can limit undesired reactions with air, light, and humidity, together with a more frequent collection of WCOs by waste disposal companies.

废弃食用油的特性、收集和储存对于生产高品质生物柴油的重要性 – 概述


近年来，由于社会对环境问题的认识不断提高，废弃食用油 (WCO) 的收集量不断增加，因为不受控制的废弃食用油 (WCO) 处置会对环境造成严重的不利影响。 WCO 是生产环保生物柴油的潜在二次原材料，可减少污染、促进可再生能源的使用并减少浪费。然而，多种降解产物的存在需要在转化前进行不同的预处理，从而显着影响该过程的经济可行性。此外，即使是经过预处理的 WCO 也可能具有无法保证生产优质生物柴油的物理和化学特性。因此，了解油在煎炸和连续储存过程中发生的降解反应非常重要。只有满足特定标准的 WCO 才会用于生产高质量的生物柴油。然后，应推广针对生物柴油生产的收集和储存方法。目前的收集方法没有规定任何特殊措施、储存容器和温度。相反，我们希望对 WCO 进行适当的收集和储存，以最大程度地减少降解，并在转化为生物柴油之前拥有良好的 WCO。任何产生 WCO 的企业都应配备专门的食品级不锈钢或塑料储油装置，以简化用过的食用油的收集并准备好按计划收集。管理家庭 WCO 似乎更复杂，但简单的操作（例如初步过滤和合适的容器）可以限制与空气、光线和湿度的不良反应，同时废物处理公司更频繁地收集 WCO。
