Explainers, teardowns, and myth-busting on waste management systems and green engineering.
Certified compostable packaging is engineered to break down in a hot industrial windrow. Put it in a garden bin, a recycling bin or a landfill and it behaves like ordinary plastic — because in those conditions, it is.
Bags, wraps and mailers are plastic, carry resin codes, and look recyclable. They are also one of the most reliable ways to shut down a sorting line.
Metals and glass survive remelting largely intact. Polymers do not. Every mechanical loop shortens chains, and the recycling symbol says nothing about how many loops a package will realistically get.
The chasing arrows around a 1, 2 or 5 identify the resin. They say nothing about whether your hauler collects it, whether the sorter can capture it, or whether anyone will buy it.
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.
