The Pyrolysis Reddit
Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen. It involves the simultaneous change of chemical composition and physical phase, and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".
Pyrolysis is a type of thermolysis, and is most commonly observed in organic materials exposed to high temperatures. It is one of the processes involved in charring wood, starting at 200–300 °C (390–570 °F). It also occurs in fires where solid fuels are burning or when vegetation comes into contact with lava in volcanic eruptions. In general, pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content, char. Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization.
The process is used heavily in the chemical industry, for example, to produce charcoal, activated carbon, methanol, and other chemicals from wood, to convert ethylene dichloride into vinyl chloride to make PVC, to produce coke from coal, to convert biomass into syngas and biochar, to turn waste into safely disposable substances, and for transforming medium-weight hydrocarbons from oil into lighter ones like gasoline. These specialized uses of pyrolysis may be called various names, such as dry distillation, destructive distillation, or cracking.

By incorporated Fresnel magnifying lenses with solar tracking for 2 axis control and an adjustable aperture you could use the thermal solar energy provided by the sun to supply the majority of the thermal energy required to break down the plastics making this a highly efficient and scalable pyrolysis reactor. Using microwaves as a way to supplement fluctuations in the solar energy provided allows for easier thermal control. Imagine 95~99% of the thermal energy gets supplied using an array of overpowered magnifying lens with an adjustable aperture to reduce the solar energy allowing you to toggle your microwaves on and off to supply that extra 1-5% of the required ideal reaction temperature. This would not only reduce the power input required drastically but would also accelerate the rate of polymer conversion reducing the total energy added to the reaction while simultaneously reducing the total heat lost to the environment over time. With enough aperture control and insulation the right design it could easily be 100% solar powered. Since this could be scaled up arbitrarily you could easily process tons of plastic in short periods of time allowing for transient operation cycles.
Plastic waste is a growing global crisis, with millions of tons of plastic ending up in landfills and oceans every year. This environmental challenge calls for innovative solutions that not only manage waste effectively but also contribute to energy security and economic growth. One promising approach is the conversion of plastic waste into oil through a process known as pyrolysis.
