In what way?

Most municipalities collect recycling and then just landfill it: https://www.earthday.org/plastic-recycling-is-a-lie/.

I find it very difficult to imagine that composting is actually legit.

You can't just label a program like this "a scam" on the basis of ... your feelings? Intuition? Biases? In other contexts, that's libel.

It looks legit to me, based on a few minutes of web searching: https://www.nyc.gov/site/dsny/what-we-do/programs/compost-gi...

It's an inference from the evidence showing that municipal recycling programs are a scam: https://www.reddit.com/r/Documentaries/comments/qjbzxi/recyc...
