Why fruits ripen more quickly in a paper bag?
Ethylene gas, which is emitted from damaged plant tissues, causes fruits and vegetable to ripen. Ethylene gas gets trapped in the paper bag thereby exposing the fruits or vegetables within causing them to ripen faster.
Does a brown bag help ripen avocados?

How do you get an avocado to ripen quickly?
You can speed up the avocado-ripening process with a piece of fruit. Put an avocado in a paper bag with a banana, an apple or a kiwi and fold to seal. These fruits produce ethylene gas, a plant hormone that aids ripening. The closed brown paper bag traps the gas inside to speed up the ripening time.

How do you ripen avocados in 10 minutes?

Why do some avocados never ripen?

Wrap it in tinfoil and place on a baking sheet. Pop it in the oven at 200°F for ten minutes, or until the avocado is soft (depending on how hard it is, it could take up to an hour to soften). As the avocado bakes in the tinfoil, ethylene gas surrounds it, putting the ripening process into hyperdrive.
How do you ripen an avocado without a brown paper bag?
If you do not have paper bags on hand, wrapping them in a newspaper will also do. This will accelerate the natural ripening process.
