Assuming unlimited energy you could just take CO2 from the atmosphere and react it with hydrogen from water to synthesize all the hydrocarbon precursors you need to then make plastics. The plastics could be burned and you start over again.
- mirimir 8y agoSure, we can burn plastics. But that can be problematic, because they often contain metals (either as filler, or in multiple layers) and are typically contaminated. In a closed system, where you're just cracking plastics, it's arguably easier to deal with contaminants. And I also suspect that you'd use less energy overall.
