> . I mean some gases get out and I guess some stuff gets eaten by birds, but mostly it's good organic matter locked away forever.

...essentially sequestered carbon.

I generally support recycling and climate action, but I actually wonder if the net benefit of throwing organic matter in landfills could be carbon negative if the gases are controlled. For organic matter, putting it in a landfill could potentially be a net positive versus recycling it or composting it (which also releases gases).

The landfills often tap the fill for methane generated by the contents. I happened to run into a guy the other day who worked at the power generation plant for one of these. The theory is that burning the methane to produce electric, and breaking it down to CO2 is generally preferable than the slow leak of it into the atmosphere where methane has a stronger greenhouse gas effect than CO2.

Edit: stronger not "strong"
