Literally this is not the case, and should be evidenced by the quotes I highlighted. It's more an intellectual deep dive on an interesting concept. It's not advocating that people ought to do this. To quote TFA:
> Carbon emissions are not the only worry. Because of the chemicals added to plastic, burning it to make fuel creates a lot of nasty air pollution. Nobody in their right mind would propose a switch to cars fuelled by plastic waste. However, it is instructive to examine the motives behind this unanimous conclusion.
Low-Tech Magazine's niche is low tech self-sufficiency, which is the main talking point of the article. Here from the first paragraph:
> During the Second World War, many motorized vehicles in continental Europe were converted to drive on firewood. 1 That happened as a consequence of the rationing of fossil fuels. Wood gas vehicles were a not-so-elegant alternative to their petrol cousins, but their range was comparable to today’s electric vehicles. In Germany alone, around 500,000 wood gas cars, buses, and trucks were operated by the end of WWII. An even more cumbersome alternative was the gas bag vehicle.
