Large quantities of vegetable biowaste are generated at marketplaces, usually in highly populated locations. On the other hand, nearby markets, hotels, and street shops generate much cooking oil waste and dispose of them in the sewage. Environmental remediation is mandatory at these places. Hence, this experimental work concentrated on preparing biodiesel using green plant wastes and cooking oil. Biowaste catalysts were produced from vegetable wastes and biofuel generated from waste cooking oil using biowaste catalysts to support diesel demand and Environmental remediation. Other organic plant wastes such as bagasse, papaya stem, banana peduncle and moringa oleifera are used as heterogeneous catalysts of this research work. Initially, the plant wastes are independently considered for the catalyst for biodiesel production; secondary, all plant wastes are mixed to form a single catalyst and used to prepare the biodiesel. In the maximum biodiesel yield analysis, the calcination temperature, reaction temperature, methanol/oil ratio, catalyst loading and mixing speed were considered to control the biodiesel production. The results reveal that the catalyst loading of 4.5 wt% with mixed plant waste catalyst offered a maximum biodiesel yield of 95%.
大量的蔬菜生物废物在市场上产生，通常在人口密集的地方。另一方面，附近的市场、酒店和街边商店产生了大量的食用油废物，并将其排放到污水中。这些地方必须进行环境修复。因此，这项实验工作集中在使用绿色植物废物和食用油来制备生物柴油。生物废物催化剂是由蔬菜废物和废食用油在生物废物催化剂的作用下产生的生物燃料制成的，以支持柴油需求和环境修复。其他有机植物废物，如甘蔗渣、木瓜茎、香蕉花梗和辣木，被用作这项研究工作的多相催化剂。最初，植物废物被单独考虑用于生产生物柴油的催化剂；其次，所有的植物废物都混合在一起形成单一的催化剂，并用于制备生物柴油。在最大生物柴油产率分析中，考虑了煅烧温度、反应温度、甲醇/油比、催化剂负载量和混合速度来控制生物柴油的生产。结果表明，在催化剂负载量为 4.5wt%的情况下，采用混合植物废料催化剂可获得最大 95%的生物柴油产率。
