Sure it&amp;#x27;s easy to add programming to work around this condition, but is it easy to integrate and test?&lt;p&gt;Anyway, crude oil is very, very cheap, and very easy to integrate into a production process. Waste plastic in the recycling stream is dirty and heterogeneous in composition and size, which makes it hard to integrate into a production process. Not impossible, but more expensive, which means that no one will do it without outside compulsion (and maybe not even then).</text><parent_chain><item><author>generalizations</author><text>I remember nearly two decades ago a PopSci article about some guy who figured out how to use microwaves to convert plastic (any hydrocarbon) into oil and natural gas.
