We want to protect the Earth's smile forever... We, Zenyu, will help you.
Zenyu Co., Ltd. was founded at the end of the 1960s, when efforts to address environmental issues became active in reflection of the pollution problems during the period of rapid economic growth. Since then, alongside the deepening commitment of the industrial sector to environmental issues, we have been assisting our customers in reducing energy costs and addressing environmental challenges through the development, manufacturing, and distribution of high-quality recycled oil. Our recycling business, which we engage in daily, goes beyond simply providing excellent products. At Zenyu, we have been quick to adopt "24-hour factory operation and 24-hour delivery," and we are expanding our bases to achieve speedy delivery, enhancing services to make recycled fuel more convenient for our customers. At the same time, we are committed to the proper disposal of waste in accordance with laws and regulations, and we operate our business in harmony with the local community, ensuring that our customers can use our products with confidence. Furthermore, we are proactively working on efficiency and reducing environmental impact during the manufacturing and delivery stages of Zenyu products, so that using our products directly contributes to our customers' environmental management efforts.
