Interested in making your own oil? If you had the right equipment you might be able to whip up a batch of oil from any carbon-based waste you gathered. This means you could go around collecting used tires, animal carcasses, or a variety of plastics and implement the technique known as thermal depolymerization to convert them into light crude oil.
The process reduces the organic materials into oil by mimicking and speeding up the processes that often lead to the creation of fossil fuels. This demands intense heat and pressure and the presence of hydrogen, carbon, and oxygen to complete, but can yield impressive results.
