Please remind me why landfills are so bad again.
It seems common to falsely believe that burying plastic in landfills has less greenhouse gas emissions than recycling it, so I'll assume that's what you are referring to.
> The existing literature on LCA of plastic waste management is vast and the results reported are generally consistent, showing that recycling generates the lowest GWP and TEU environmental impacts.
LCA: lifecycle analysis
GWP: global warming potential
TEU: Total Energy Use
