Converting Waste Oil into Diesel Fuel With VTA Technology
At WANRONG, Waste Oil is what we do. With the advanced technology. we offer, used oil is converted into high quality diesel fuel in a sustainable way to preserve environment as a source of energy.
An Eco-Friendly Approach to Dealing with Waste Oil
The conversion of waste oil into diesel fuel is not only beneficial for the environment, it is also beneficial in that a valuable product can be produced. Through the recasting of waste oil, we can reduce our reliance on new mineral resources and respond to increased demands for diesel fuel in an economical and environmentally friendly manner.

New Diesel Synthesis with Waste Oil Directly-produced Technology
We have a state of the art plant to derive good quality diesel fuel from reconstituted oil in an exacting and controlled process. With advanced facilities and production technologies, we can guarantee the quality of diesel fuel we produce is as good as virgin diesel oil, and that's why WANRONG is a trusted alternative to purchasing diesel from recycled oil.
