No. The numbered triangle used as a resin identification code identifies the plastic material. It does not guarantee that an item belongs in your local recycling collection.
ASTM's published description of the coding standard says these are not recycling codes and do not establish that collection or processing systems exist. The US Environmental Protection Agency independently explains that a resin code does not guarantee recyclability in a particular area.
Material identification and local acceptance answer different questions. The code also does not establish that an item contains recycled material. For disposal, use the instructions from your local recycling provider rather than treating the number alone as permission to put an item in the bin.
A resin code identifies material, not a guaranteed recycling route. Local collection instructions determine whether the item is accepted.

Yes. The companies announced trials to assess contrail avoidance in real flight operations. The announcement does not establish fleet-wide climate benefits.
No. The study reports about 7.4 extra days per decade—not in total—equivalent to roughly a month over 1979–2024.
They can slow melting beneath small covered areas, but early results do not show they can stop glacier retreat at a meaningful scale.
