Food is a quarter of what goes into landfills and is linked to well over half the methane that escapes them. The reason is that a landfill is not a compost heap — it is the opposite of one.
Paper is one of recycling's genuine success stories — 68.2% recovery, the largest modelled share of MSW greenhouse-gas reduction. It is also finite at the fibre level. The loop is a cascade, not a circle.
The chemistry is real. The label is doing a lot of work. If the outputs are hydrogen gas and mineral carbonate, no plastic has been recycled — something else has happened.
