A process for converting waste plastic into oil includes: subjecting the waste plastic to be in contact with a plurality of far-infrared ray heating rods in a reactor which contains an agitator configured to distribute the waste plastic; converting the waste plastic into a liquid form resultant decomposition by thermal decomposition and pyrolysis in the reactor; fractionating the resultant decomposition product to obtain gas, light oil, and crude diesel oil; obtaining a sludge from a bottom portion of the reactor and transferring the sludge to a blending tank; transferring the light oil to the blending tank; mixing the sludge and the light oil using a high-speed shearing machine to produce a sludge and light oil mixture; transferring the sludge and light oil mixture to a homogenizer; and blending the sludge and light oil mixture at the homogenizer to form a blended oil.

A process is hereby provided for permanently (>1000 years) reducing carbon dioxide in the atmosphere. The process involves the cultivation of tree and plant waste (biomass), the conversion of the biomass in a reactor to a carbon product, e.g., charcoal, and subsequent storage of the carbon product. The reactor used for conversion is run at a low temperature, e.g., 300-450? C. Thus, there is negligible cracking. The product is primarily a solid carbon product, which is safe and can be easily handled. The carbon product can also be safely stored. In one embodiment, the carbon product is buried in a location that is tested for limited oxygen at burial depths. The permanence of the CO.sub.2 reduction is therefore assured.
