A book I read as a kid was set in a future where they were out of oil and couldn't make new plastic. Plastic became very expensive and things like plastic bowls were used as signs of wealth. The plot involved kids who were taken and forced to mine plastic from old landfills. https://en.wikipedia.org/wiki/The_Ear,_the_Eye_and_the_Arm https://en.wikipedia.org/wiki/The_Ear,_the_Eye_and_the_Arm
