Here are a few companies contact information to start:

If you find any other gas station information not listed, please share. I just basically, asked why they are not recycling and suggested that the begin offering it as an option. These were not nasty letters/emails that I sent because I don't know that it should be the first option. Especially with these companies, who probably only hear negative feedback. If anyone feels like sharing their letters/emails, please do.
